NAD+
Recharge your system — and feel like yourself again

Yes — your body makes its own NAD+ naturally, and in fact, it’s been doing that all your life. But like a lot of things, production tends to slow down as you get older. On top of that, everyday stress, poor sleep, certain medications, and even a bad diet can all chip away at your NAD+ levels faster than your body can replace them.

That gradual decline doesn’t always show up overnight, but over time, it can leave you feeling more drained, foggy, or sluggish than usual — even if you’re technically “healthy.” That’s where NAD+ therapy comes in: not to replace something foreign, but to give your body more of what it’s already built to use.

NAD+ plays a big role in how your body makes and uses energy — but that’s just the start. It helps convert the food you eat into fuel your cells can actually use, which is key for everything from thinking clearly to moving your muscles. It also helps repair damaged DNA, supports your metabolism, and keeps your cells functioning the way they’re supposed to.

Another big job of NAD+ is helping your cells respond to stress and stay resilient over time. That includes protecting your brain, maintaining healthy sleep cycles, and slowing down some of the changes we associate with aging. So when NAD+ levels start to dip, it’s not just about having less energy — it can affect how sharp you feel, how well you recover, and even how well your body defends itself from long-term wear and tear.

Low NAD+ levels can sneak up on you, and the symptoms often look like things we chalk up to “getting older” — even though they’re not always inevitable. You might notice your energy fading faster than it used to, or that your workouts leave you more wiped out than before. Brain fog, trouble concentrating, or feeling mentally sluggish can also show up when NAD+ is running low.

Other signs might include poor sleep, mood dips, or just feeling like your body’s recovery time is dragging — whether that’s after exercise, illness, or even a stressful day. While none of these symptoms on their own prove your NAD+ levels are low, they can be a clue that your cells aren’t firing on all cylinders anymore.

NAD+ levels naturally decline as you get older — and the drop can start earlier than you might expect. Research shows that by the time you hit middle age, your NAD+ levels may already be half of what they were in your 20s. That steady decrease doesn’t just affect your energy; it can also play a role in how quickly you recover from illness or injury, how well your brain functions, and how fast signs of aging start to show up.

Several things can speed up the decline too, like chronic stress, poor sleep, inflammation, or even certain medications. The result? Your body doesn’t work quite as efficiently behind the scenes, which can leave you feeling foggy, worn out, or just not like yourself.

When your NAD+ levels dip too low, it can throw off the way your cells create energy and repair themselves — and over time, that can affect how you feel and function day to day. You might notice your energy isn’t as steady, your thinking feels slower or fuzzier, or it takes longer to bounce back from workouts, stress, or illness.

Low NAD+ is also linked to signs of faster aging, like trouble sleeping, slower metabolism, and more visible wear and tear on the body. In more severe cases, depleted NAD+ levels have been associated with chronic conditions tied to aging and inflammation. Your body still tries to keep up, but with less NAD+ to work with, things just don’t run as smoothly.

NAD+ plays a key role in how your body ages — not just on the outside, but at the cellular level. It helps support DNA repair, reduce oxidative stress, and regulate the health of your mitochondria (which are like tiny power plants inside your cells). All of those processes are tied to how well your body holds up over time.

As NAD+ levels decline with age, your cells can’t maintain themselves as efficiently. That’s when you start to see signs of aging creep in — things like slower recovery, less energy, memory issues, or increased inflammation. Some researchers believe that by keeping NAD+ levels higher, you may be able to slow some of that decline and support better aging from the inside out.

Yes — and it’s a big one. Your brain uses a ton of energy, and NAD+ helps keep that energy flowing by supporting the processes that power your cells. But it doesn’t stop there. NAD+ also plays a role in protecting brain cells from damage, supporting repair pathways, and helping regulate inflammation — all of which matter when it comes to long-term brain health.

When NAD+ levels drop, it can show up as brain fog, forgetfulness, mental fatigue, or slower thinking. That’s why some people turn to NAD+ therapy to support sharper focus, better memory, or clearer thinking — especially if they’ve noticed a decline with age, stress, or illness.

Your lifestyle can have a surprisingly big impact on your NAD+ levels — and not in a good way. Chronic stress, poor sleep, lack of physical activity, and even a diet high in processed foods can all drain your body’s NAD+ stores faster than it can replenish them. That’s because your body burns through NAD+ when it’s under pressure, whether from mental strain, physical illness, or just not getting enough rest.

Over time, those habits can leave you running on empty — which might show up as low energy, slower recovery, brain fog, or other signs of burnout. The good news? Supporting your NAD+ levels through better sleep, stress management, and targeted treatments can help reverse some of that wear and tear and get you feeling more like yourself again.

Technically, yes — but it’s not something most doctors test for in routine labs. Measuring NAD+ levels accurately requires specialized testing, and even then, it can be tricky. NAD+ exists inside your cells, not just floating around in your bloodstream, so standard blood work won’t give you a clear picture of what’s going on.

Because of that, most providers don’t rely on NAD+ lab levels to make decisions about treatment. Instead, they look at your symptoms, medical history, and overall health picture to decide whether NAD+ therapy might be helpful. If you’re dealing with things like low energy, poor focus, slow recovery, or signs of aging that don’t seem to match your lifestyle, it might be worth exploring — even without a blood test to “prove” your levels are low.

If you feel like your energy, focus, or recovery just isn’t what it used to be — even if your lifestyle hasn’t changed much — NAD+ therapy might be worth looking into. As NAD+ levels drop with age, your body gets less efficient at creating energy, repairing cells, and handling stress. That can show up in all kinds of ways, from mental fog and poor sleep to sluggish metabolism and slower recovery from workouts or illness.

NAD+ therapy is designed to help replenish those levels so your cells can function the way they’re supposed to. Some people turn to it for help with aging-related changes, while others use it to bounce back from burnout, support brain health, or just feel sharper and more resilient day to day. It’s not a cure-all, but for the right person, it can be a powerful tool to support how you feel and function.

That’s one of the main reasons people try it — and often one of the first things they notice improving.

NAD+ plays a key role in how your body makes and uses energy. When your levels drop, your cells can’t keep up with the demand, and you’re more likely to feel drained, sluggish, or like you’re constantly running on empty. Boosting NAD+ helps recharge your system at the cellular level, which can translate to steadier energy, better stamina, and fewer of those midday crashes. It’s not like a jolt of caffeine — more like flipping the switch back on for how your body’s supposed to work.

It can — especially if low NAD+ levels are part of what’s throwing things off in the first place.

NAD+ isn’t just about physical energy; it also supports healthy brain function and plays a role in how your body responds to stress. When levels are low, you might feel mentally flat, less motivated, or more easily overwhelmed by things that wouldn’t normally bother you. Bringing those levels back up can help restore some of that emotional balance. You may find that your mood lifts, your motivation improves, and you bounce back from stress more easily. It’s not a cure-all for mental health, but it’s one piece of the puzzle that can help you feel more like yourself again.

It often does — especially if brain fog or trouble concentrating has crept in over time.

Your brain uses a huge amount of energy, and NAD+ is a big part of how that energy gets made and managed. When NAD+ levels drop, your mental sharpness can take a hit. You might notice that it’s harder to focus, stay organized, or think clearly. For many people, restoring NAD+ helps clear away some of that fog. It won’t turn you into a genius overnight, but it can help your brain feel more switched on and capable again — like the lights are finally back on upstairs.

It can — especially if you’ve been feeling like your body just doesn’t bounce back the way it used to.

NAD+ plays a key role in how your cells repair themselves, manage inflammation, and produce energy. When your levels are low, recovery can feel slower and harder, whether you’re dealing with sore muscles after a workout or fatigue after getting over a cold. By supporting cellular repair and energy production, NAD+ therapy may help you feel more resilient — less wiped out after exertion, and better equipped to handle physical stress. It’s not a miracle cure, but for some people, it makes a noticeable difference in how quickly they bounce back.

There’s growing evidence that NAD+ plays an important role in how your immune system functions. Your body uses it to power the cells that defend against infection and manage inflammation — which means when your NAD+ levels are low, your immune response might not be as strong or efficient.

NAD+ therapy isn’t a substitute for sleep, nutrition, or other healthy habits, but it may help support your body’s ability to respond to stress and illness. Some people notice they feel less run down, bounce back faster when they do get sick, or just seem to stay healthier overall. It’s subtle, but for those with low NAD+, a steady boost can make a meaningful difference.

It can be — especially if your energy, focus, or motivation just isn’t what it used to be. When you’re dealing with chronic stress, long hours, or mental fatigue, your body burns through NAD+ faster than usual. That drop can leave you feeling drained, foggy, or stuck in low gear.

NAD+ therapy helps replenish what your body’s used up, so you’ve got more of the raw material you need to power through physically and mentally. It won’t magically erase stress, but a lot of people say they feel more clear-headed, steady, and resilient — like they’ve finally got a little more gas in the tank again.

There’s growing research suggesting that NAD+ plays a big role in how we age — not just on the outside, but deep at the cellular level. Your body needs NAD+ to repair DNA, support healthy cells, and keep inflammation in check. As NAD+ levels drop with age, that repair work slows down, and signs of aging tend to show up more quickly.

NAD+ therapy doesn’t stop aging (nothing does), but it may help support the systems that keep you feeling and functioning younger for longer. Think of it like giving your cells the resources they need to stay sharp, recover faster, and hold the line a little better as time marches on.

It might. NAD+ plays a key role in how your body turns food into energy — and how efficiently your metabolism runs overall. When NAD+ levels are low, your cells can’t do that job as well, which may leave you feeling sluggish, storing more fat, and burning fewer calories throughout the day.

By helping your body use fuel more efficiently, NAD+ therapy may support a healthier metabolism. It’s not a fat-burning miracle, but it could give your body the edge it needs to respond better to things like diet, exercise, and other efforts to lose weight or maintain a healthy one.

There’s growing evidence that NAD+ plays a role in your body’s internal clock — the system that helps regulate when you feel awake and when you feel sleepy. This system, known as the circadian rhythm, relies on a complex network of signals, and NAD+ helps keep that network running smoothly.

When NAD+ levels drop, it can throw off those rhythms, potentially leading to restless nights or trouble falling asleep. Some people who try NAD+ therapy report deeper, more restful sleep and an easier time waking up feeling refreshed. It’s not a sleep aid in the traditional sense, but if low NAD+ is part of what’s messing with your rest, restoring it could make a noticeable difference.

It really depends on the person — and what you’re hoping to feel. Some people notice subtle improvements within the first week or two, like steadier energy or clearer thinking. Others may take longer, especially if NAD+ levels have been low for a while or if other health factors are involved.

Because NAD+ supports so many different systems in your body, the changes it brings can be gradual and build over time. You might not wake up one day feeling like a new person, but many people describe it as a quiet shift — more stamina, less brain fog, better recovery, or an overall sense of feeling more like themselves. Most people who stick with therapy for a few months tend to notice the biggest changes.

Yes — while NAD+ is considered safe for most people, there are a few health conditions that could make it a poor fit. If you have uncontrolled high blood pressure, serious heart issues, or a history of certain cancers, NAD+ therapy might not be recommended. The same goes for anyone with active liver or kidney problems, or those with unexplained symptoms that haven’t yet been evaluated by a provider.

When you sign up for NAD+ treatment through Claya, you’ll fill out a detailed health questionnaire that helps us flag any of these issues early. If something in your history suggests NAD+ might not be safe or effective for you, a provider will review your responses and let you know if we recommend holding off or exploring other options first.

It’s also important to keep your care team in the loop. If you’re being treated for any ongoing health concerns, you’ll want to talk to your doctor before starting NAD+ — just to make sure it fits safely into your bigger picture

Yes — for most people, NAD+ is considered safe to use over the long haul, especially when it’s used at the right dose and checked in on now and then. Your body already makes it on its own, so you’re not introducing something foreign. You’re just giving your system more of a key resource it already knows how to use.

We don’t have decades of long-term research yet, but current studies — and clinical experience — suggest that ongoing use is both safe and well-tolerated. The most common side effects are pretty mild and tend to go away quickly if they show up at all.

As with anything, the key is to make sure it’s a good fit for you. If you’re using NAD+ through Claya, your provider will keep tabs on how you’re doing and make sure your treatment stays aligned with your goals.

In most cases, yes — NAD+ is generally safe to take alongside other medications. It’s not a drug in the traditional sense; it’s a molecule your body already uses every day to run essential processes. That said, it’s still important to be cautious.

Some medications might affect how your body uses NAD+, or vice versa. That’s why your provider will always review your medical history and current prescriptions before signing off on treatment. If there’s anything that looks iffy, they’ll either adjust your dose or let you know it’s not the right time to start.

So while NAD+ usually plays well with others, you’ll want to be upfront about anything you’re taking — including supplements and over-the-counter meds — so your provider can make the safest call for you.

Nope — NAD+ therapy isn’t approved for use during pregnancy or while breastfeeding. Even though your body naturally makes NAD+ on its own, there’s not enough research yet to know how supplementing it might affect a developing baby or show up in breast milk.

If you’re pregnant or nursing, you’ll need to hold off for now. Your provider can walk you through safer options until the timing’s right.

In many cases, yes — but it depends on your specific situation. NAD+ therapy isn’t off-limits just because you have a chronic condition like diabetes, hypertension, or heart disease. In fact, some early research suggests NAD+ might even offer support for metabolic health, energy regulation, and cellular repair in people with those issues.

That said, it’s not a one-size-fits-all deal. Your provider will review your medical history and current medications to make sure NAD+ is safe and makes sense for you. If anything in your health record raises a red flag, they’ll either adjust your dose or let you know if NAD+ isn’t the right fit.

In most cases, NAD+ doesn’t conflict with everyday supplements or over-the-counter products. It’s generally well tolerated and doesn’t rely on the same pathways that many medications or herbs do. But that doesn’t mean interactions are impossible.

Even natural products can have real effects, and certain combinations might not be ideal. If you’re taking anything regularly — including vitamins, herbal blends, or workout enhancers — it’s important to mention it during your intake. Your provider will look everything over to make sure there aren’t any red flags, and will reach out if anything needs a closer look.

Usually not. NAD+ works in a different way than most medications or supplements, so it’s not likely to clash with what you’re already taking. But that doesn’t mean you should skip the details.

Just because something’s sold over the counter doesn’t mean it can’t have an effect — or cause problems when combined with something else. So if you’re using anything regularly, even if it seems minor, be sure to include it when you fill out your intake. Your provider will go through the full list and make sure everything looks safe together.

Nope — you won’t need to do any lab work before getting started. NAD+ therapy is prescribed based on your symptoms, goals, and medical history, which you’ll go over in a detailed intake form.

That said, if you’ve had recent labs done for another reason, or if there’s something specific you’re concerned about, you can always bring that up during your consultation. But for most people, the process is straightforward, and you can start without needing blood tests first.

Yes — in fact, people over 60 may have even more to gain from NAD+ therapy. As we get older, our natural NAD+ levels tend to drop, which can show up as slower recovery, lower energy, brain fog, or just a general sense of feeling “off.” Supporting those levels with therapy can help your cells function more like they used to, which may make a noticeable difference in how you feel day to day.

As with any treatment, it’s still important to review your health history before starting — especially if you have chronic conditions or take other medications — but age alone isn’t a reason to hold back.

Side effects from NAD+ therapy are usually pretty mild, if they show up at all — things like flushing, slight nausea, or a headache early on. These often go away as your body gets used to the supplement. That said, if something feels off or you’re not sure whether what you’re experiencing is normal, don’t try to tough it out.

Reach out to your provider so they can take a look and, if needed, adjust your dose or make sure there’s not something else going on. It’s always better to check in than to second-guess or stop on your own.

Yes — NAD+ therapy is flexible. If you need to pause for travel, budget, or just to see how you feel without it, that’s totally fine. There’s no hard reset or long ramp-up period when you come back to it.

Some people take it consistently, while others cycle on and off depending on how they’re feeling or what’s going on in their lives. If you’re unsure about timing or how to ease back in, your provider can help you figure out the best approach.

It depends on what you’re looking for — but NAD+ works differently than most energy supplements or brain boosters. Instead of giving you a quick spike like caffeine or some nootropics do, NAD+ goes deeper, supporting the actual processes that make energy in your cells and keep your brain sharp over time.

Most energy supplements work by stimulating your nervous system. That might help in the short term, but it can also lead to crashes or burnout. NAD+ helps restore what your body may be running low on — giving you more stable energy, better focus, and resilience without the highs and lows.

If you’re after a quick buzz, a stimulant might do the trick. But if you’re looking to feel better, think clearer, and function at a higher level all day (and all week), NAD+ offers a foundation that other supplements usually don’t touch.

Usually, yes — and sometimes it actually works better that way. NAD+ helps recharge the systems that keep your brain running smoothly, while nootropics tend to act more like targeted boosts. So if you’re using something to sharpen focus, improve memory, or just stay more alert, NAD+ might help give those tools a stronger foundation to work from.

That said, it’s still worth being thoughtful about what you’re mixing. If you’re already taking supplements that affect your sleep, heart rate, or mood, adding more on top could throw things off. It’s a good idea to run your full stack by your provider to make sure everything plays nice together — and that you’re not overdoing it in ways that could backfire.

Sure — things like exercise, sleep, and diet can help your body make and use NAD+ more efficiently. But here’s the thing: those habits work slowly, and they only get you so far. If your NAD+ levels have already taken a hit (from stress, aging, illness, or just life), lifestyle changes might not be enough to bring them back up to where you actually feel a difference.

That’s where NAD+ therapy comes in. It gives your system the direct support it needs to refill the tank and start running more smoothly again. Think of it as a way to accelerate the progress you’re hoping to see from your healthy habits — not replace them, but help them work better and faster.

For a lot of people, yes — it can be. Caffeine and stimulants give you that quick jolt, but it usually comes with a crash, and the more you rely on them, the less effective they feel over time. NAD+ works differently. It doesn’t just hype you up — it helps your cells actually make more energy and use it more efficiently.

The result isn’t a spike — it’s a steadier, more sustainable kind of energy that doesn’t leave you feeling wired, jittery, or wiped out later. If you’re tired of chasing that next cup of coffee just to get through the day, NAD+ therapy might be the reset your system’s been waiting for.

They’re different tools for different jobs — but they can complement each other, depending on what your body needs.

Hormone treatments like TRT or thyroid support are designed to correct specific hormonal imbalances. If your testosterone or thyroid levels are low, bringing them back into range can have a big impact on your energy, mood, and metabolism. NAD+ works a bit more broadly. It’s not a hormone — it’s a molecule your cells use to make energy, repair damage, and keep your systems running smoothly.

Some people find that NAD+ gives them the boost they were hoping hormone therapy would deliver, especially if their labs didn’t show a clear deficiency. Others use NAD+ alongside hormone therapy to help amplify the benefits. If your hormones are in a decent place but you still feel foggy, tired, or just not quite yourself, NAD+ could be worth a look.

IV therapy can be effective — but it’s not always convenient, and it’s not always necessary.

With NAD+ injections or nasal spray, you can get many of the same benefits as IV therapy without needing to block off time for an appointment, sit through an infusion, or pay extra for clinic overhead. You’re still getting real, prescription-strength support — just in a way that fits into your life more easily.

Most people also find that consistent use over time gives them better results than the occasional IV drip. It’s less about the big “hit” and more about giving your body what it needs to work better day in and day out.

Both forms can be effective — but they don’t always feel the same, and they don’t always work the same way for everyone.

Injectable NAD+ is the more established option and tends to deliver the strongest, most noticeable results. Because it goes straight into your system, it’s often better absorbed and used more efficiently by your cells. Most people who start with injections report improvements in energy, focus, recovery, and overall resilience within a few weeks — sometimes sooner.

Nasal NAD+ is newer and more convenient, but it may be milder. It’s a good option for people who don’t love needles or want something quick and portable. Some folks use it on its own; others pair it with injections for a more flexible routine.

The right option for you depends on your goals, lifestyle, and how your body responds — and your provider can help you figure out which one makes the most sense.

Most people don’t feel “wired” on NAD+ — it’s not a stimulant like caffeine or Adderall. That said, because NAD+ supports energy production at the cellular level, some people do notice a boost in alertness or mental clarity not long after taking it. For that reason, it’s usually best to take it earlier in the day so it doesn’t interfere with your wind-down routine at night.

In some cases, people actually find that NAD+ improves their sleep over time. Once your energy is more balanced during the day, your body may find it easier to rest and recover at night.

It’s possible, especially when you’re just starting out or if the dose is too high for your body to handle right away. Some people report mild headaches, nausea, or a general feeling of being off — usually when their body’s adjusting to the increased NAD+ levels. These effects are typically short-lived and tend to fade as your system adapts.

If you do feel uncomfortable, it might help to lower the dose temporarily or take it with food. And if symptoms persist or feel like more than just a rough patch, it’s always a good idea to check in with your provider to make sure everything’s on track.

Allergic reactions to NAD+ are pretty rare, but they can happen. Most people tolerate it well, especially since it’s something your body naturally makes. That said, any injectable or nasal treatment carries at least a small chance of irritation, redness, or sensitivity at the application site.

If you notice symptoms like itching, swelling, trouble breathing, or a rash — especially shortly after taking it — stop using it and contact a medical provider right away. That kind of reaction is unusual, but it’s not something to ignore. If you’ve had allergic reactions to medications in the past, it’s worth mentioning before you get started.

As of now, NAD+ therapy looks pretty safe for long-term use — especially when you’re following a medical plan and using doses that make sense for your body. Since NAD+ is something your body already makes and uses every day, most people tolerate it well, even over time.

That said, long-term research is still ongoing. We don’t yet have decades of data like we do with some older medications, so it’s smart to keep checking in with your provider and tracking how you’re feeling. If anything changes or new concerns come up, you’ll want to talk about it and adjust your treatment if needed.

If you start feeling worse after taking NAD+, don’t just push through it — check in with your provider. Most people tolerate NAD+ without any issues, but sometimes the dose might be too high, or your body might just need a little time to adjust. In rare cases, it could be a sign that something else is going on.

The good news is that NAD+ dosing is flexible, and small changes can make a big difference. Whether you’re dealing with headaches, queasiness, jitteriness, or just not feeling right, your provider can help figure out what’s behind it and make a plan to get you back on track.

Not quite — at least not for most people. Oral supplements like NMN (nicotinamide mononucleotide) or NR (nicotinamide riboside) are precursors, which means your body has to convert them into NAD+ before they can do any good. And while some of that conversion does happen, it’s not especially efficient. You’re relying on your digestive system, your metabolism, and a bunch of individual factors to turn those precursors into something useful.

NAD+ therapy skips the middleman. It gives your body the actual molecule it needs, in a form it can use right away — no conversion required. That makes a big difference in how much your cells can absorb and how fast you feel it working.

For people trying to address serious fatigue, burnout, or brain fog, the direct approach tends to be more effective. Precursors and pills might help a little, but they’re not always strong enough to move the needle in a meaningful way.

With NAD+ therapy, the shift can be surprisingly noticeable. You might not wake up feeling like a brand new person after a single dose, but over the first few weeks it’s common to feel your energy stretch further, for that foggy, sluggish feeling to lift. You recover faster from stress, whether it’s mental or physical. You feel steadier, sharper, and just… more like yourself.

Some people notice they’re sleeping better, handling pressure more easily, or finding it easier to stay focused without having to reach for caffeine all day. Others feel like they’ve finally broken out of a low-energy rut they couldn’t shake with supplements, diet, or willpower alone.

The results build gradually — but for many, it’s enough to feel like your body and mind are finally working with you, instead of against you.

Not exactly. Caffeine gives you a quick, artificial spike — a jolt that wears off fast and can leave you feeling more drained afterward. NAD+ works differently. It doesn’t stimulate your nervous system; instead, it supports the processes your cells use to make energy in the first place.

The result is a more stable, lasting kind of energy. It won’t feel like a buzz or a rush — more like your tank just doesn’t hit “empty” as quickly. Most people notice they’re getting more done, thinking more clearly, and not dragging by late afternoon, all without needing to rely on coffee or energy drinks to push through.

It definitely could — especially if you’re looking for an edge in energy, focus, or recovery. Even if you’re in good shape, your NAD+ levels still decline with age, stress, poor sleep, and intense physical or mental demands. That drop can chip away at your resilience in ways you might not even notice until they start stacking up.

For some people, NAD+ therapy helps sharpen the edges — giving them steadier energy throughout the day, faster bounce-back after workouts, or better mental clarity under pressure. It’s not about fixing something that’s broken; it’s about supporting the systems that keep you feeling your best, even when life gets busy or stressful.

It’s not a magic bullet — but it can absolutely help. Burnout and chronic fatigue often have layered causes: stress, poor sleep, nutrient depletion, hormonal shifts, and a system that’s just plain worn out. NAD+ plays a role in how your body handles all of those things.

By replenishing your cellular energy stores and supporting how your body repairs itself, NAD+ can help lift the fog and ease the drag that comes with long-term exhaustion. People often say they feel more stable, more clear-headed, and more like themselves again after a few weeks of treatment. It’s not about masking symptoms — it’s about giving your system what it needs to recharge at a deeper level.

Yes — and honestly, that’s where the real magic happens. NAD+ can help recharge your system, but your daily habits shape how well your body holds onto those gains. Eating nutrient-rich foods, getting solid sleep, and managing stress all support your body’s natural ability to make and use NAD+ effectively.

Think of it like fueling and tuning up a car. NAD+ gives you the high-quality fuel, but your habits keep the engine running smoothly. The more you support your body with good sleep, less sugar, steady movement, and real meals (not just snacks and caffeine), the better your results are likely to be.

It definitely can. NAD+ plays a key role in how your cells produce energy and repair themselves, which matters a lot when you’re pushing your body. Whether you’re lifting heavy, doing cardio, or just trying to stay active as you age, higher NAD+ levels can help your muscles work more efficiently — and bounce back faster afterward.

Many people notice they don’t hit that wall as quickly during workouts, and they recover with less soreness or downtime between sessions. It’s not a magic pre-workout that gives you a sudden burst of energy, but over time, it helps your body perform better and handle stress — both physical and mental — more effectively.

Yes — though maybe not in the flashy, overhyped way you’ve seen on wellness blogs. NAD+ supports your body’s natural detox systems by helping fuel the enzymes that break down and clear out cellular waste. It also plays a role in DNA repair and reducing oxidative stress, which is closely tied to inflammation and how your body responds to illness or injury.

There’s also growing evidence that healthy NAD+ levels support immune function by helping your immune cells respond efficiently without going into overdrive. That means your body may be better equipped to deal with everyday stressors — and potentially bounce back faster when something throws you off.

Yes. Jet lag and shift work both throw off your body’s internal clock, leaving you feeling groggy, foggy, and off-kilter. Since NAD+ plays a role in regulating circadian rhythms and cellular energy, keeping your levels supported may help your body adjust more smoothly.

While it’s not a magic fix, some people find that NAD+ helps them feel more alert during the day, sleep more soundly at night, and bounce back faster after long flights or schedule changes. It’s especially helpful when paired with good sleep habits, light exposure, and a little planning ahead.

Because NAD+ supports cellular repair, energy production, and reduced oxidative stress, it plays a role in how your body handles aging at a deeper level. That means healthier skin cells, better collagen production, and improved circulation — all things that can contribute to a fresher, healthier look.

Some people notice their skin looks more hydrated or clear, or that their hair feels stronger or grows more easily. That said, NAD+ isn’t a beauty treatment in the traditional sense. It works from the inside out, helping your body rebuild and restore at the cellular level — which can absolutely show up in the mirror, but gradually, not overnight.

Most people don’t feel a sudden jolt or dramatic shift — it’s more of a steady change that sneaks up on you in a good way. You might notice your energy lasts longer through the day, or that you’re thinking more clearly without having to push so hard. Some people say their mood feels lighter, their workouts feel easier, or they’re finally sleeping through the night without tossing and turning.

You might also notice you’re recovering faster from stress, travel, or illness — the kind of stuff that used to knock you down for longer than it should. The best way to tell if it’s working? Look at how you feel overall, day to day. If things are starting to feel smoother, steadier, and easier to handle, it’s a good sign NAD+ is doing its job.

Routine lab work isn’t required while using NAD+ therapy. It’s considered safe enough at standard doses that ongoing blood testing usually isn’t necessary, especially if you’re generally healthy and not taking other medications that might interact.

That said, if you have a complicated medical history, or if you’re curious about how NAD+ might be affecting things like inflammation, metabolic health, or energy production on a deeper level, you can talk with your provider about optional testing. But for the average person, there’s no mandatory lab schedule built into the plan.

Not all at once, but yes — over time, many of the benefits will start to fade if you stop NAD+ therapy completely. Think of it like keeping your tank topped up. NAD+ helps support how your cells function, so when you’re consistently giving your body more of it, things tend to run more smoothly. When you stop, your levels will eventually drift back down, especially if you’re older or under a lot of stress.

That doesn’t mean you’ll crash or feel terrible the next day — it’s more of a gradual shift. You might notice your energy dipping a little faster, your focus not feeling quite as sharp, or that post-workout recovery takes longer than it used to. If that happens, you can always restart therapy and get back on track.

The main difference comes down to how the NAD+ gets into your system — and how much of it your body can actually use.

Injectable NAD+ goes under the skin and gets absorbed directly into your bloodstream, which tends to give you a steadier and more noticeable effect. It’s great if you’re dealing with low energy, brain fog, burnout, or if you just want the strongest results possible.

Nasal NAD+ is less intense but super convenient. It’s absorbed through the lining of your nose, and while the amount that gets into your system is a bit lower than with injections, it still gives your NAD+ levels a solid boost. A lot of people like it because it’s fast, easy, and doesn’t involve needles.

Some people stick with just one form; others use both together — like doing injections a couple of times a week and using nasal spray on the in-between days. Your provider can help you figure out what’s right for your goals and routine.

Yes, you can. Some people start with injections and later switch to the nasal spray for convenience, or the other way around if they want a stronger or more consistent effect. Your provider can help you figure out which option fits your goals, schedule, and preferences best — and switching isn’t a big deal if your needs change down the road. In some cases, both forms can even be used together, depending on what you’re trying to achieve.

That depends a bit on your goals and how your body responds, but most people start with a few doses each week. In Claya’s program, that usually looks like 2 to 3 injections per week, or daily use if you’re using the nasal spray.

If you’re just getting started, your provider will likely begin with a lower dose to see how you respond, then gradually increase it over the first few weeks. From there, the dose and schedule can be fine-tuned based on how you’re feeling and what kind of results you’re seeing.

Some people do best with a consistent weekly routine; others take breaks or taper down once they’re feeling steady. You don’t have to figure that out alone — we’ll help you find the rhythm that works for you.

NAD+ dosing is usually gradual — you start low and build up as your body adjusts. In Claya’s program, most people begin with a lower dose (like 50 mg injected three times a week) for the first month. That gives your system time to adapt and helps minimize any mild side effects some folks notice early on.

In month two, the dose typically increases to 100 mg three times a week. By the third month, most people are at 200 mg, either twice or three times a week, depending on how they’re responding and what their goals are. From there, your provider can fine-tune things — if you’re doing great at a certain dose, you might stay there. If you need more support, they can adjust your dose or dosing frequency.

It’s flexible, and we’ll walk you through each step so you’re not left guessing.

Yes — your dosage isn’t set in stone. If you’re not getting the results you’re hoping for, your provider can review how you’re responding and adjust your dose if needed. Most people start low and increase gradually, especially with injectables. That helps your body ease in without overdoing it.

It’s also normal for your needs to shift over time. Stress, sleep, activity levels, and even seasonal changes can affect how your body responds. If anything feels off or underwhelming, it’s worth checking in — sometimes a small tweak makes a big difference.

You don’t have to eat beforehand, but it’s usually a good idea — especially when you’re just getting started. Some people feel a little lightheaded, queasy, or just “off” when they take NAD+ on an empty stomach, and having something in your system can help smooth that out. A small snack or a light meal beforehand can make the experience more comfortable, especially with the injectable form.

That said, once your body’s used to it, you might find you can take it either way without any trouble. But if you’re feeling weird after your dose, try timing it with food and see if that helps.

Nope, don’t double up. If you miss a dose, just skip it and pick back up with your next scheduled one. NAD+ works best when it’s used consistently over time, but taking extra all at once won’t “catch you up” — and could leave you feeling wired, nauseous, or just off.

One missed dose isn’t going to wreck your progress, so don’t stress about it. Just get back on track and keep going.

Yes — like anything else, more isn’t always better. Your body needs NAD+ to function well, but flooding your system with too much can throw things off. Most people do best on a steady, moderate dose that matches their goals and how their body responds over time.

Taking more than you need might lead to side effects like nausea, dizziness, or an upset stomach. It could also end up being a waste — your body can only use so much at once, and the rest just gets flushed out. If you’re not sure whether your dose is right, it’s always better to ask than to guess.

If you take a little more than your usual dose once in a while, chances are you’ll be fine — but you might feel it. Some people report mild nausea, flushing, dizziness, or an upset stomach when they overshoot their dose. It’s not usually dangerous, but it’s not exactly pleasant either.

That said, regularly taking more than you’re supposed to isn’t a great idea. Your body can only use so much NAD+ at a time, and pushing past that doesn’t mean better results — it just increases the odds of side effects and wastes product. If you ever feel off after a dose, or if you’re not sure what to do, reach out to your provider for guidance.

Not exactly. NAD+ isn’t like caffeine or certain medications where your body adjusts and stops responding. Your cells use NAD+ to carry out essential tasks — so giving your body more of it doesn’t create a “tolerance” in the traditional sense. That said, the effects may feel less dramatic over time, especially once your levels have stabilized and your baseline improves.

Think of it like exercise: at first, you notice big changes, but as your body adapts, progress becomes more about maintenance and fine-tuning. If you ever feel like NAD+ isn’t doing as much as it used to, it might be time to check in with your provider and reassess your dose or routine.

Most people don’t need to cycle off NAD+, especially if they’re using it at standard doses. Since your body naturally uses and breaks down NAD+ every day, ongoing support can help keep levels steady, especially if you’re older or dealing with chronic fatigue, stress, or other demands on your system.

That said, your needs might change over time. Some people choose to take breaks once they’re feeling better, or use NAD+ in phases depending on what’s going on in their life. There’s no one-size-fits-all rule here, and your provider can help you decide what makes the most sense for your body and goals.

Yes. Weekly use is generally considered safe, especially at standard doses. In fact, many people take NAD+ two or three times a week as part of their regular routine. That frequency tends to strike a nice balance between keeping your levels up and giving your body time to use it effectively.

Of course, everyone’s a little different. If you’re noticing side effects or just not feeling quite right, it’s worth checking in. But for most folks, weekly or even more frequent use isn’t too much — it’s part of how NAD+ therapy is designed to work.

You’ll feel it — not always right away, but your body’s usually pretty good at sending signals when something’s off. If your dose is too low, you might not notice much of anything. Maybe a slight bump in energy or focus, but not enough to feel like it’s really helping. That’s usually a sign the dose needs to be bumped up or taken more consistently.

If your dose is too high, your body might feel overstimulated — not jittery like with caffeine, exactly, but more like your system is running a little too fast. Some people feel restless, have trouble sleeping, or get a weird wired-but-tired sensation. That’s your cue to back off a bit and let your provider know so they can help you adjust.

The goal isn’t to crank things up as high as they’ll go. It’s to find that sweet spot where you feel clear, steady, and more like yourself — without overdoing it.

There’s no strict “do not” list, but there are a few things worth keeping an eye on while you’re using NAD+ therapy. First, avoid taking it too late in the day — especially if you’re sensitive to energy shifts — since some people find it perks them up a little too much to sleep well. Morning or midday is usually your best bet.

Heavy alcohol use, smoking, and chronic stress can all interfere with how your body uses NAD+, so cutting back on those can help you get better results. And while NAD+ is generally safe alongside most medications and supplements, it’s smart to double-check with your provider if you’re taking anything new — especially stimulants or anything that affects your nervous system.

Other than that, just listen to your body. If something starts to feel off, bring it up during your next check-in.

It’s simple and streamlined. First, you’ll complete a detailed online questionnaire about your health history, current symptoms, medications, and goals. A licensed provider will review your answers to make sure NAD+ is safe and appropriate for you. If you’re a good fit, they’ll write your prescription and set up your treatment plan. You’ll get your first month’s supply, and if you decide to keep going, follow-up consults will help fine-tune your dose over time.

Your first consultation with Claya is all done online — no phone calls, no waiting rooms. You’ll fill out a detailed intake questionnaire that covers your symptoms, medical history, lifestyle, and any medications or supplements you’re taking. From there, one of our licensed providers reviews everything to make sure NAD+ is a safe, appropriate option for you.

If you’re a good fit, you’ll get a prescription that starts with a lower dose, so your body has time to adjust. You’ll also get clear instructions on how to take it and what to expect in the first few weeks. No lab work is required to get started, and you’ll have access to follow-up check-ins to help fine-tune your treatment over time.

The whole thing usually takes less than 10 minutes. Since it’s asynchronous, you don’t need to set aside time for a live appointment — just fill out the intake form at your own pace, and your answers will be reviewed by a licensed provider shortly after. Most people hear back with next steps within a day or two. It’s quick, convenient, and designed to fit easily into your schedule.

Your first refill happens after about a month, so you’ll do a short follow-up check-in then. After that, follow-ups shift to a quarterly rhythm — roughly every three months — unless something in your health or symptoms changes and you need an adjustment sooner. These check-ins are asynchronous too, so there’s no need to schedule a video call or visit. Just fill out the follow-up form when it’s time, and your provider will review everything to make sure you’re still on track.

When it’s time for a refill, you’ll get a reminder to complete a quick follow-up form. That lets your provider know how you’re doing, whether you’ve had any side effects, and if you’re still seeing benefits. As long as everything looks good, your next refill will be sent in — no need to book an appointment or jump through hoops. Just check your inbox when it’s time, fill out the form, and you’re all set.

Not at all. You don’t need to sign up for a long-term plan just to give it a shot. Claya’s program starts with a single month of treatment, so you can see how it feels and whether it’s something you want to continue. Some people notice a difference right away, while others take a few weeks to feel the full effects — but there’s no pressure to keep going unless it’s genuinely helping you feel better.

There’s no official approval or cure here, but some people with ADHD or ADD find that NAD+ gives them a noticeable edge — especially with mental clarity, focus, and staying on task. NAD+ supports cellular energy and brain function, so it may help smooth out some of the mental fatigue and distractibility that often come with neurodivergent brains.

It’s not a replacement for ADHD medications, but it might complement them, or offer a gentler option for folks looking to avoid stimulants. That said, everyone’s brain is different, so the best way to know if it helps is to try it and pay attention to how you feel.

Yes — but not by directly raising your hormone levels. What NAD+ actually does is help your body run more efficiently behind the scenes. That includes things like cellular repair, energy production, and signaling between systems, including your endocrine (hormone) system.

If your hormones are already being supported through something like TRT or thyroid treatment, NAD+ can give that support a boost by helping your body respond better. And if you’re not on hormone therapy, but your system just feels out of whack, NAD+ might help bring a little more balance and resilience to the mix. It’s not a magic fix — but for a lot of people, it’s a missing piece.

It might — especially if your symptoms are tied to low energy, brain fog, or feeling worn down. While NAD+ doesn’t affect hormone levels directly, it does support the systems your body leans on to stay balanced and resilient during hormonal shifts.

Many people going through perimenopause or menopause report that NAD+ helps them feel clearer, more stable, and less drained. It can support energy, sleep quality, mood, and even how well your body bounces back from stress. It’s not a substitute for hormone therapy, but for some, it’s a valuable layer of support — especially when your system feels like it’s running on fumes.

No. There is no specific diet people using injectable semaglutide need to follow, though making healthy changes to your eating habits may make it easier to lose weight and maintain your weight once you reach your goal.

No. There is no evidence that injectable semaglutide interacts with any specific foods, though people do sometimes find that avoiding fatty foods helps minimize any side effects they may be experiencing during the early phase of treatment.

No. There’s no reason to adjust your workout routine or schedule just because you’re taking injectable semaglutide, though starting an exercise program if you haven’t already can improve your overall health and maximize your weight loss results.

You most certainly can. Injectable semaglutide makes you feel fuller faster, and helps you stay feeling full longer, so you may find yourself eating smaller portions that you were before. Don’t feel like you have to clean your plate — ask for a doggie bag instead.

A little alcohol is fine while you’re taking injectable semaglutide; just do it in moderation. Excessive alcohol can not only increase the risk of side effects, it can also interfere with your weight loss. 

Many people like the convenience of only having to take their medication once per week, but if you’re uncomfortable with injections you can opt for one of the other forms of semaglutide. Simply tell your provider that you’re not comfortable injecting yourself.
