The Science

Why NMN?

NMN (Nicotinamide Mononucleotide) is a direct precursor to NAD+, a molecule your cells rely on for energy production, DNA repair, and metabolic function. NAD+ levels decline naturally with age — by your 40s, you may have roughly half the NAD+ you had at 20.

How Juvi NMN works

Juvi delivers 500 mg of pharmaceutical-grade NMN per capsule. Once absorbed, NMN is converted into NAD+ in your cells. Higher NAD+ levels support the sirtuins — a family of proteins linked to longevity, cellular repair, and metabolic health.

What the research says

Human clinical trials have shown that oral NMN supplementation safely and effectively raises blood NAD+ levels. A 2021 study published in Science demonstrated that NMN supplementation improved muscle function and insulin sensitivity in older adults. Ongoing research continues to explore NMN's role in healthy ageing.

Our formulation

Juvi NMN contains one ingredient: pure β-NMN. No fillers, no binders, no unnecessary additives. Each batch is third-party tested for purity and potency. We publish our certificates of analysis so you can verify exactly what is in every capsule.

How to take it

Take one capsule daily, preferably in the morning. Consistency is more important than timing. Most customers report noticing steadier energy levels after 2–4 weeks of daily use.
