It's the headline molecule of the longevity boom — sold as IV drips and injectables promising energy and "reversing aging." Here's what NAD+ actually is, what the evidence does and doesn't show for those wellness claims, and exactly where it stands with the FDA in 2026.
NAD+ — nicotinamide adenine dinucleotide — is a coenzyme found in every living cell. It plays a central role in how cells produce energy and run repair processes, and its levels are understood to decline with age. That biology is real and well-established. It is not a peptide in the strict sense, but it sits squarely in the same longevity/wellness market peptides occupy, which is why it's covered here.
In that market, NAD+ is sold mainly as IV infusions and injectables marketed for energy, recovery, focus, and "anti-aging." The honest headline: the underlying biology being real does not mean the marketed wellness benefits are proven. It is not a vitamin you simply top up, and it is not an FDA-approved treatment for any of those uses.
NAD+ for wellness and anti-aging is not an FDA-approved drug, and the nuance matters:
Want the live picture? Our regulatory-status tracker shows exactly where NAD+ and other compounds stand right now, with the dated primary sources.
NAD+ augmentation has clear biological activity — raising NAD+ levels in blood and tissue is measurable, and the molecule's role in cellular metabolism is genuine. That's the part that's solid.
The wellness claims are where the gap opens. A 2026 systematic review found no rigorous outcomes trials of intravenous or intramuscular NAD+ itself for anti-aging or wellness — commercial enthusiasm has badly outpaced the clinical evidence, especially for the IV format, which is the most popular and most expensive. Most human data that exists is on oral precursors (NR, NMN), not injectable NAD+, and even there clinical effectiveness for "anti-aging" remains inconclusive. Treat confident promises of reversed aging or dramatic energy gains with skepticism.
Because there's no FDA-approved NAD+ product for these uses, there is no official dosing. Commonly reported subcutaneous doses land around ~50–100 mg per injection, while the IV protocols clinics run are often much higher — frequently ~250–500 mg or more per session. These figures vary widely by source, and there are no validated standardized doses or endpoints for "wellness NAD therapy." To be clear: these are not approved or standardized doses — they reflect what clinics and the wider community commonly report using today, shared for education, not medical advice. Any decision belongs with a licensed provider.
Injectable NAD+ is sometimes supplied as a freeze-dried (lyophilized) powder that must be reconstituted with bacteriostatic water before use. The math — concentration and the volume to draw — trips a lot of people up, and a misplaced decimal is an easy way to get the dose badly wrong. That's what our free tool is for:
The most commonly reported issue with NAD+ IV infusions is infusion-related discomfort — nausea, flushing, cramping, or chest tightness, often tied to how fast the drip runs. Beyond that, long-term safety for repeated wellness use is not well established, and there are no universally accepted guidelines for dosing or monitoring. Because much of the supply is compounded or research-use-only and unregulated, purity, sterility, and accurate labeling are real concerns — which is why sourcing and the setting of administration matter as much as the molecule itself.
If you're considering NAD+ therapy, the responsible path runs through a licensed provider who can weigh your situation, not a marketing page promising to reverse aging. Questions worth asking: Is this an FDA-approved product? (No — so what exactly is being administered, and from where?) Is there third-party testing and a certificate of analysis? Is it compounded or research-use-only? What does the provider make of the actual evidence? This isn't legal or medical advice — it's the baseline diligence any unapproved substance deserves.
No. NMN and NR are precursors the body can convert toward NAD+, usually taken orally as supplements. Injectable/IV NAD+ is the coenzyme itself. They have different evidence bases and different regulatory stories.
Not in the strict sense — it's a coenzyme (a dinucleotide), not a chain of amino acids. We cover it because it lives in the same longevity and wellness market as the peptides in our library.
There's no rigorous evidence that it does. NAD+ has real biological roles, but the 2026 evidence shows no solid outcomes trials of IV NAD+ for anti-aging. Claims of "reversing aging" run well ahead of the data.
We don't sell it and we don't direct consumers to buy unapproved substances. There's no FDA-approved NAD+ product for wellness use; what's sold is typically compounded or research-use-only. If a licensed provider determines it's appropriate, sourcing and testing should be part of that conversation.
