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.
