1Nicotinamide Adenine Dinucleotide
Core Coenzyme

NAD+

500mg

What it is

NAD+ (Nicotinamide Adenine Dinucleotide) is a coenzyme present in every living cell. It sits at the center of how cells convert food and oxygen into usable energy, and it serves as a substrate for enzymes involved in DNA repair and healthy cellular function.

Why it's in the formula: NAD+ levels naturally decline with age — a finding documented across human tissue research. Kelvara delivers NAD+ directly at 500mg per serving, rather than as a precursor molecule, so what's on the label is what's in the bottle.*

2Flavonoid Polyphenol
Plant Flavonoid

Quercetin

250mg

What it is

Quercetin is a naturally occurring flavonoid found in onions, apples, capers, and other plants. It is among the most widely studied dietary flavonoids for its potential effects on antioxidant activity and longevity-associated pathway support.

Why it's in the formula: Quercetin is studied for its role in longevity-associated pathways and may support healthy cellular aging when taken consistently. We include it at 250mg alongside NAD+ because the two share overlapping research areas.*

3Polygonum Cuspidatum Extract
Natural Resveratrol

Japanese Knotweed (98% Resveratrol)

150mg

What it is

Resveratrol is a polyphenol produced by plants as a stress response compound. Japanese Knotweed root is the most concentrated natural source and is standardized to 98% resveratrol purity in our formula.

Why it's in the formula: Resveratrol is studied as a SIRT1 activator — the same longevity enzyme family that NAD+ may help fuel. At 150mg, Kelvara matches the dose used in published human research (Timmers et al., Cell Metabolism 2011), sourced from Japanese Knotweed for maximum purity.*
