NAD+
A coenzyme central to how your cells produce energy and repair themselves, studied for its declining role in the biology of aging.
A coenzyme central to cellular energy
NAD+ (nicotinamide adenine dinucleotide) is a coenzyme present in every living cell, where it plays a central role in energy metabolism and cellular repair. Levels are understood to decline with age, which is why it has become a focus of research into healthy aging. At Meridian it is offered as a compounded medication — meaning it is prepared by a licensed pharmacy — and is used only under a provider’s guidance.
Supporting how cells make energy
NAD+ is a key participant in the reactions that convert nutrients into usable cellular energy and in pathways involved in DNA repair. Research explores whether restoring NAD+ availability may support these processes. It is typically administered as a subcutaneous dose on a cadence your provider sets.
- ✓Central to the reactions cells use to convert nutrients into energy
- ✓Studied in the context of DNA repair and cellular aging pathways
- ✓Delivered as a provider-guided subcutaneous protocol at a set cadence

This is general education, not medical advice. Whether NAD+ is appropriate for you is determined by a licensed provider.
Why oversight matters here
This is a compounded medication, so a licensed provider must confirm it’s appropriate for you before it can be dispensed. The review checks your health history, current medications, and goals to ensure it’s a safe fit.
This therapy requires review by a licensed provider before it can be dispensed. You’ll complete a short online visit; a provider evaluates whether it’s appropriate for you and, if so, authorizes it.
Your care journey, step by step
From first visit to follow-up — calm, transparent, and guided by a licensed provider throughout.
What the research explores
A plain-language look at the areas of study. Research is evolving and varies in strength — we present it honestly, not promotionally.
NAD+ is well established as an essential coenzyme in energy metabolism. Its role in this process is foundational cell biology.
Studies have observed that NAD+ levels decline with age, prompting research into whether restoring them supports cellular function.
Research has investigated NAD+’s involvement in DNA repair and the enzymes tied to cellular maintenance. Human clinical evidence remains limited and ongoing.
NAD+ is not FDA-approved. It is a compounded medication; the research into its use for aging is early and evolving.
Our Science Library — evidence summaries, mechanisms, limitations, and provider commentary — is expanding.
NAD+, answered
No. It is a compounded medication prepared by a licensed pharmacy, not an FDA-approved drug. It is provided only when a licensed provider determines it is appropriate for you.
Typically as a subcutaneous injection on a cadence your provider sets. Your provider will give you specific dosing guidance and everything needed to administer it.
Yes. This therapy requires provider review. You’ll complete a short free online visit, and a provider decides whether to authorize it.
For long-term longevity goals, membership adds check-ins, tracking, and provider adjustments over time — but it isn’t required for a reviewed purchase.
