Frequently Asked Questions

What is NMN?

NMN (Nicotinamide Mononucleotide) is a naturally occurring molecule found in small amounts in foods like broccoli, avocado, and edamame. It is a direct precursor to NAD+, a coenzyme essential for energy production and cellular repair. Juvi delivers a concentrated, pure dose that food alone cannot provide.

How much NMN is in each capsule?

Each Juvi capsule contains 500 mg of pure β-NMN. This is the dose used in most published human clinical trials.

When should I take it?

We recommend taking one capsule in the morning, with or without food. Morning dosing aligns with your body's natural circadian rhythm and avoids any potential effect on sleep quality.

How long before I notice a difference?

Most customers report noticing steadier, more consistent energy levels after 2–4 weeks of daily use. Results vary by individual, age, and baseline NAD+ levels.

Is NMN safe?

Published human clinical trials have found NMN supplementation to be safe and well-tolerated at doses up to 1,200 mg per day. Juvi contains 500 mg per capsule. As with any supplement, consult your doctor if you are pregnant, breastfeeding, or taking medication.
