How NAD is the Answer for Chronic Fatigue Illness

How does NAD+ therapy actually work?

NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in every cell of your body that’s essential for energy production and cellular repair. When you receive NAD+ therapy—whether through injections, IVs, or oral precursors—you’re replenishing levels that naturally decline as you age. NAD+ works inside your mitochondria to help convert food into cellular energy (ATP), supports enzymes called sirtuins that regulate aging processes, and assists in repairing damaged DNA. The therapy essentially gives your cells the raw materials they need to function optimally. The key thing to remember is that NAD+ works best as part of an overall wellness approach—it supports your body’s natural processes rather than replacing them.

Am I a good candidate for NAD+ therapy?

NAD+ therapy is typically considered for adults experiencing age-related energy decline, brain fog, or recovery challenges—especially those over 30 when NAD+ levels start dropping significantly. People dealing with chronic fatigue, post-viral symptoms (like long COVID), or general feelings of slowing down often explore this option. That said, your age and symptoms aren’t the whole story—your doctor will look at your complete health picture, including current medications, existing medical conditions, and your overall wellness goals. The best way to know if you’re a candidate is to have an honest conversation with your healthcare provider about what you’re experiencing and what you hope to achieve. They can determine if NAD+ therapy is a safe and appropriate option for your specific situation.

What side effects should I expect?

Most people tolerate NAD+ therapy well, but some experience temporary side effects—especially when first starting or with higher doses. The most common reactions include mild nausea, a warm or flushed feeling, minor injection site tenderness, or brief headaches. These usually show up during your first few treatments and typically fade as your body adjusts over a couple of weeks. Some people feel temporarily more tired initially as their cells adapt to increased NAD+ availability. For IV therapy, effects tend to be more noticeable during the infusion itself—things like a metallic taste, chest tightness, or stomach discomfort that resolve quickly after the session ends. Serious side effects are rare. Your doctor will likely recommend starting with lower doses and gradually increasing to help minimize any discomfort.

How long does it take to see results?

Most people start noticing subtle changes within the first 2–4 weeks—better sleep quality, slightly improved focus, or feeling less drained by the end of the day. More significant improvements in energy, mental clarity, and overall vitality typically develop over 6–12 weeks of consistent treatment. The timeline varies from person to person based on your starting NAD+ levels, age, lifestyle factors, and how consistently you follow your protocol. It’s important to set realistic expectations: cellular restoration is gradual, not instant. Think of it as recharging a battery that’s been slowly draining for years—it takes time to rebuild. The people who see the best long-term results are those who stick with therapy for at least 3 months and combine it with healthy lifestyle habits they can maintain.

Will my insurance cover NAD+ therapy?

Insurance coverage for NAD+ therapy is honestly pretty limited right now. Most insurance plans consider it experimental or wellness-based rather than medically necessary, which means you’ll likely be paying out of pocket. A few plans might cover it if prescribed for specific conditions like chronic fatigue syndrome or certain neurological issues, but that’s the exception rather than the rule. If your doctor prescribes NAD+ as part of treating an approved condition, you might have better luck getting at least partial coverage—but don’t count on it. Your best bet is to call your insurance company and ask specifically about coverage for NAD+ therapy or the particular product your provider recommends. If insurance won’t cover it, many telehealth companies offer more affordable self-pay options, subscription pricing, or payment plans that make treatment more accessible.

What are the main differences between NAD+ injections, IV therapy, and oral supplements?

The main differences come down to bioavailability, convenience, and cost. Subcutaneous injections (like those from telehealth companies) deliver NAD+ precursors directly into your tissue for high absorption—you can do them at home, they’re relatively affordable, and they provide steady support. IV therapy delivers NAD+ straight into your bloodstream at higher concentrations, which some people feel more immediately, but it requires clinic visits, takes 2–4 hours per session, and costs significantly more. Oral supplements (NMN, NR) are the most convenient since you just swallow a pill, but bioavailability is lower because they have to survive your digestive system—though quality matters a lot here. Some people respond better to one method than another based on absorption, lifestyle, and how their body processes NAD+. Your healthcare provider can help you figure out which delivery method aligns best with your goals and budget.

Do I need to take NAD+ therapy forever?

This is a great question that doesn’t have a one-size-fits-all answer. Since NAD+ naturally declines with age and your body doesn’t suddenly start producing more on its own, many people find they need ongoing supplementation to maintain the benefits they’ve achieved. Think of it like managing any age-related change—some things require consistent support. That said, every situation is different. Some people use NAD+ therapy for specific recovery periods (like bouncing back from illness) and then stop, while others incorporate it as a long-term wellness strategy. You might also cycle your dosage—taking breaks or reducing frequency once you’ve reached a good baseline. The decision should be made with your doctor based on how you feel, your health goals, and how your body responds. The key is having a realistic plan for what maintenance looks like for you.

Can I drink alcohol while using NAD+ therapy?

Moderate alcohol consumption is generally considered safe while using NAD+ therapy, but there’s an important catch: alcohol actually depletes your NAD+ levels. When you drink, your body uses NAD+ to metabolize the alcohol, which works against what you’re trying to achieve with therapy. Heavy or frequent drinking can significantly reduce the benefits you’d otherwise experience. That said, occasional moderate drinking won’t completely derail your progress—just be aware you’re creating more work for your cells. Some people actually find that NAD+ therapy helps them feel less interested in alcohol or reduces hangover severity. If you have a history of liver issues or are using NAD+ specifically for recovery purposes, your doctor might recommend avoiding alcohol altogether. The bottom line: occasional drinks are usually fine, but part of optimizing your cellular health might mean rethinking how alcohol fits into your routine.

Are compounded NAD+ products safe?

Compounded NAD+ can be a legitimate option when manufactured by licensed, reputable compounding pharmacies that follow strict sterility and quality standards. However, compounded products aren’t FDA-approved, which means they haven’t gone through the same rigorous testing and oversight as pharmaceuticals. The quality can vary significantly between pharmacies. If you’re considering a compounded option due to cost or customization needs, make sure it comes from a pharmacy that’s registered with your state board and ideally accredited by organizations like PCAB (Pharmacy Compounding Accreditation Board). Never buy NAD+ from random websites, social media ads, or sources that seem sketchy—there are counterfeit and contaminated products circulating online. Your healthcare provider can help you identify trustworthy compounding pharmacies and ensure you’re getting a quality product from a legitimate source.

What happens if I miss a dose?

Don’t panic if you miss a dose—it happens to everyone. For weekly injections, if you remember within a couple days of your scheduled dose, go ahead and take it, then get back on your regular schedule. If it’s been several days and you’re almost at your next scheduled dose, just skip the missed one and continue as normal. Never double up on doses to make up for a missed one. For daily protocols (whether injections or oral supplements), take the missed dose as soon as you remember unless it’s almost time for your next one. Missing an occasional dose won’t erase your progress, but consistency matters for maintaining stable NAD+ levels. Set phone reminders, keep your supplies in a visible spot, or use a medication tracking app if you tend to forget. If you’re frequently missing doses, talk to your doctor—maybe a different schedule or delivery method would work better for your lifestyle.

Will NAD+ therapy help with muscle recovery and athletic performance?

Many athletes and active people use NAD+ therapy specifically for recovery and performance support, and there’s some science backing this up. NAD+ plays a role in muscle repair, reducing oxidative stress after intense exercise, and helping your mitochondria produce energy more efficiently during workouts. Some research suggests it may help with endurance and reduce recovery time between training sessions. That said, NAD+ isn’t a magic performance enhancer—you won’t suddenly run faster or lift heavier just from taking it. Where people tend to notice benefits is in feeling less wiped out after hard workouts, recovering faster between sessions, and maintaining energy throughout longer training blocks. To maximize any athletic benefits, you’ll want to pair NAD+ with proper nutrition (especially adequate protein), good sleep, and smart training programming. It’s also worth combining it with other recovery-focused supplements like glutathione or L-carnitine if your doctor thinks that makes sense for your goals.
