How should NAD+ be stored?

In lyophilized powder form, NAD+ is stable at room temperature short-term but should be refrigerated (2–8°C) for longer storage and kept away from light and moisture. Once reconstituted, keep refrigerated and use within 30 days. Avoid freeze-thaw cycles.

Is NAD+ approved by the FDA?

No. NAD+ is not FDA-approved for human use. NextSelf Labs sells NAD+ strictly as a research chemical for laboratory research.

What is the purity of your NAD+?

All NextSelf Labs NAD+ is manufactured to ≥99% purity and verified by third-party laboratories using HPLC and mass spectrometry. The Certificate of Analysis for every batch is available on this page — match the batch number on your vial to the COA header to verify.

Why are NAD+ levels so important?

NAD+ is required for hundreds of enzymatic reactions, including those that produce energy, repair DNA, and regulate gene expression. As levels decline with age, the cellular processes that depend on it slow down accordingly — which is why so much aging research now focuses on NAD+ status.

How is NAD+ different from NMN or NR?

NMN (nicotinamide mononucleotide) and NR (nicotinamide riboside) are precursor molecules that the body converts into NAD+. NAD+ itself is the active coenzyme. Research uses all three depending on the specific question being asked.

Do I need a prescription to purchase NAD+?

No. NextSelf Labs sells NAD+ as a research chemical for laboratory use only.

About the Peptide

The molecule at cellular center.

NAD+ (nicotinamide adenine dinucleotide) is a coenzyme present in every living cell — essential to the chemical reactions that produce cellular energy and to the enzymes that govern DNA repair, gene expression, and the cellular response to stress.

NAD+ levels decline measurably with age. Research has shown that women in their forties have roughly half the NAD+ of women in their twenties, a decline that parallels nearly every metabolic and energetic shift associated with midlife — fatigue, slower recovery, the cellular markers of aging.

Published research has documented NAD+’s role in mitochondrial function, sirtuin activity (a family of longevity-associated enzymes), DNA damage response, and the metabolic processes that connect cellular health to whole-body resilience. It sits at the foundation of modern longevity research.

Research Applications

Where longevity research lives.

NAD+ has become shorthand for an entire field of women’s longevity research — because almost every aging conversation, eventually, comes back to it.

Cellular Energy

NAD+ is essential to the mitochondrial reactions that produce ATP — the cellular currency of energy. Research has documented its role in metabolic capacity and exercise tolerance.

Sirtuin Activation

The sirtuin family of enzymes — widely studied in longevity research — requires NAD+ to function. As NAD+ declines with age, sirtuin activity declines with it.

DNA Repair & Cellular Resilience

NAD+ is consumed by PARP enzymes during DNA damage response, making cellular NAD+ status a key variable in research on cellular aging and resilience.
