What's in every capsule

NAD+ (nicotinamide adenine dinucleotide).The fuel. Settled biochemistry: your repair genes, the sirtuins, cannot run without it. Vivacelle is built around it.

Quercetin (as quercetin dihydrate).The drain blocker. In animal studies, worn-out cells pull in an enzyme, CD38, to burn through the fuel. In cell studies, quercetin blocks it.

Japanese knotweed extract, standardized to resveratrol.The second key. In cell studies, the resveratrol in Japanese knotweed switches the repair genes on.

Two capsules with breakfast. Every day.

Keep the bottle where you will see it in the morning — next to the coffee, or by your walking shoes. Two capsules with breakfast is all it asks. The fuel only works if it keeps coming, so take it every day.

If you take other medications, show the label to your pharmacist before you start.

How many capsules, and how often?
Two capsules with breakfast, daily. 60 per bottle — a 30-day supply.
How big are the capsules / are they easy to swallow?

Can I take it with my medications?
Vivacelle is a dietary supplement, not a medication. If you take other medicines, show the label to your pharmacist before you start.
Is this like an NAD+ IV drip?
No — Vivacelle is two daily capsules, not an IV drip, a clinic, or a therapy.
Does it raise my NAD+?
We do not make that claim. Vivacelle is built around NAD+ — the fuel your repair genes run on — and two plant helpers for those repair genes.

You do not have to decide today whether it worked. You get 180 days, counted from the day your order arrives. If you're not glad you tried it, contact our support team for a full refund.
