NAD+ is a coenzyme every cell uses to make energy and repair DNA, and studies observe lower levels with age in some tissues; the benefits of NAD+ injections, sprays or supplements are still being studied. Compounded NAD+ is not FDA-approved; a licensed provider decides whether it fits you. **Medically reviewed by** [Linda West-Conforti, RN](/medical-team/) · [CA RN #389453](https://search.dca.ca.gov/details/4500/RN/389453/) · 2026-09-22. Founding Nurse · Patient Care Lead. People choose NAD+ for energy, mental clarity and healthy aging. NAD+ is a coenzyme every cell uses to make energy and repair DNA, and studies observe lower levels with age in some tissues; the benefits of NAD+ injections, sprays or supplements are still being studied. Compounded NAD+ is not FDA-approved; a licensed provider decides whether it fits you. A pilot study of intravenous NAD+ measured metabolites in eight treated participants and three controls; it did not establish clinical benefits or a subcutaneous dosing schedule. [Source: NAD+ intravenous pilot study](https://pubmed.ncbi.nlm.nih.gov/31572171/) ## What NAD+ actually does NAD+ (nicotinamide adenine dinucleotide) is a **coenzyme found in every cell**, and its role in cellular energy metabolism is well established — it's directly involved in the pathways that turn nutrients into usable energy. That biochemistry is solid and uncontroversial. (Deeper explainer: [what NAD+ is](/blog/what-is-nad-coenzyme-explained/).) It's why REMEVi frames NAD+ around **general wellness**, and prescribes it after an individual evaluation — see [NAD+ injections](/nad-injections/) for the forms and how care works. ## What human studies measured, and what they have not shown | Question | What human research has measured | What has not been shown | |---|---|---| | Energy metabolism | NAD+ is required for the reactions that make ATP; brain-imaging work has linked NAD levels with brain energy metabolism | That extra NAD+ from an injection, spray or supplement changes how energetic people feel | | Aging | Lower NAD+ levels with age in some human tissues (an observational finding) | That raising NAD+ slows aging or extends life in people | | NAD+ levels | Some NAD+ treatments and precursors raise NAD+ or its metabolites in blood | That a higher blood level produces a health benefit | | Focus and mood | Interest based on the brain's energy needs | Improvements in focus, memory or mood from NAD+ treatment | | At-home injections | Published dosing protocols from pharmacies and clinics | Any controlled trial of at-home subcutaneous NAD+ injections | The left column is biology and observation. The right column is where the marketing usually sits. Keeping the two apart is the honest way to read any NAD+ benefits list. ## Where the hype outruns the evidence NAD+ is marketed for **aging, addiction recovery, cognitive performance and more** — and the human evidence for those specific claims is **still emerging and far from settled.** Some are active areas of research; none is established in the way the marketing implies. So the honest framing is: - **Well established:** NAD+ is a coenzyme essential to cellular energy metabolism. - **Still emerging / unsettled:** most of the big lifestyle and disease claims attached to NAD+ products. Anyone promising dramatic, guaranteed results is selling, not informing. ## Is NAD+ good for you? Your body needs NAD+: every cell uses this coenzyme to turn food into usable energy and to run enzymes involved in DNA repair. Whether taking extra NAD+ as an injection, nasal spray or supplement is good for you is a separate question that human research has not answered. A licensed provider can weigh it against your own health history. ## Does NAD+ really work? It depends on what you mean by work. Studies show NAD+ is central to cell energy and that some NAD+ treatments raise NAD+ levels in blood. They have not shown that raising those levels changes how people feel, think or age. Compounded NAD+ is not FDA-approved, and it has not been studied as a finished product. ## What does NAD+ do for your body? Inside your cells, NAD+ carries electrons in the reactions that turn nutrients into ATP, the fuel cells run on. It is also used up by enzymes such as sirtuins and PARPs that take part in DNA repair and cell signalling. That is established biochemistry, not a promise about what a prescribed preparation will do for you. ## Why we won't hand you a guaranteed benefits list Two reasons: compounded NAD+ is **not FDA-approved as a finished product** and hasn't been studied as one, and **outcomes are individual** — they vary with age, health, medications, and lifestyle. Instead of a promise, the useful information is that this is a prescription preparation, evaluated and supervised by a provider, with realistic expectations set for *you.* Before starting, read [are NAD+ injections safe](/are-nad-injections-safe/) for the FDA status and the risks. [Source: FDA: risks of compounded medicines](https://www.fda.gov/drugs/human-drug-compounding/understanding-risks-compounded-drugs) ## Better questions for a provider 1. Given my health, is NAD+ even appropriate for me? 2. What would you realistically expect, and how would you measure it? 3. What are the risks in my case? > **Want an honest, individual assessment?** [Start a clinical evaluation with REMEVi](/nad-injections/) — a licensed US provider tells you whether NAD+ makes sense for you, with bilingual care.

NAD+ prescribed by REMEVi is a non-FDA-approved compounded medication that requires a prescription from a licensed provider after an individual evaluation. Individual results vary.* ## Injectable preparation safety FDA has received reports of severe chills, shaking, vomiting and fatigue after NAD+ injectable medicines, with some patients requiring medical care. It warns that food-grade ingredients are unsuitable for sterile compounding. Those reports do not establish a risk frequency for a particular preparation.

Your body needs NAD+: every cell uses this coenzyme to turn food into usable energy and to run enzymes involved in DNA repair. Whether taking extra NAD+ as an injection, nasal spray or supplement is good for you is a separate question that human research has not answered. A licensed provider can weigh it against your own health history. ### Does NAD+ really work? It depends on what you mean by work. Studies show NAD+ is central to cell energy and that some NAD+ treatments raise NAD+ levels in blood. They have not shown that raising those levels changes how people feel, think or age. Compounded NAD+ is not FDA-approved, and it has not been studied as a finished product. ### What does NAD+ do for your body? Inside your cells, NAD+ carries electrons in the reactions that turn nutrients into ATP, the fuel cells run on. It is also used up by enzymes such as sirtuins and PARPs that take part in DNA repair and cell signalling. That is established biochemistry, not a promise about what a prescribed preparation will do for you. ### What are the benefits of NAD+ injections? The honest answer is that benefits of NAD+ injections have not been established in people. The biological role of NAD+ is well understood, which is why it is studied for energy metabolism and healthy aging. A small intravenous pilot study measured NAD+ metabolites, but it did not show clinical benefits or set a home-injection dose. ### Are NAD+ benefits the same for everyone? No. Response varies with age, health status, other medications and lifestyle, and no single benefit profile applies to all patients. That is why NAD+ is prescribed individually after a clinical evaluation and reviewed over time, rather than sold as a one-size-fits-all product. Your provider can set realistic goals and decide whether continuing makes sense. ## Sources linked in this article These are the external references linked in the article.
