NMN and NAD+: What This Popular Longevity Ingredient Actually Does

NMN (nicotinamide mononucleotide) has become one of the most talked-about ingredients in the longevity supplement space over the past few years, usually mentioned alongside NAD+.

NAD+ (nicotinamide adenine dinucleotide) is a coenzyme present in every cell, involved in energy production and a wide range of cellular processes. NAD+ levels are well-documented to decline with age, which is the basic premise behind NMN’s popularity: NMN is a direct precursor the body converts into NAD+, so supplementing with it is a way of trying to support levels that naturally decline.

We offer NMN two ways. Our NAD+ Renew Capsules are the convenient option — two capsules, done, no measuring. Our Pure NMN Powder is unflavored and 99%+ pure with nothing else added, aimed at people who want to dose more precisely, take it sublingually, or who are just optimizing cost per milligram at higher doses.

This is a newer, still-developing area of supplement research compared to something like caffeine or magnesium, which have decades of established use behind them. It’s worth going in with that context, and worth a conversation with your physician if you’re considering it as part of a broader longevity-focused routine, especially alongside other supplements like TMG.

If cellular energy and healthy aging support is your main interest, NMN and TMG are commonly stacked together — see our methylation explainer for how TMG fits into that picture.
