Questions
Good to know.
How do I take it?
One capsule a day, whenever suits you. Most customers take it with breakfast so it becomes automatic. Each bottle is clearly a 30, 60 or 90 day supply, so you always know where you are.
What are the ingredients?
Each capsule contains 500mg of pure NMN (nicotinamide mononucleotide) and nothing else besides the capsule shell. No blends, no fillers, no bulking agents.
How is it tested?
Every batch is tested by an independent accredited laboratory before it goes anywhere near a bottle, verifying purity and that each capsule contains exactly what the label says. See the certificate for yourself on our transparency page.
What is NMN?
NMN is the direct precursor your body uses to make NAD+, a coenzyme found in every living cell. The full two minute explainer is further up this page. See “Meet NAD+”.
How does the subscription work?
Your delivery schedule matches your supply: 30 day bottles arrive monthly, 60 day every two months, 90 day every three. You save 25% on every delivery, and you can pause, skip or cancel anytime from your account. No phone calls, no small print.
What if it doesn't work for me?
Then it costs you nothing. Every order is covered by our 100 day money-back guarantee: if you don't feel a difference, send it back for a full refund. No forms, no fuss.
