Evidence-Based
We only use ingredients with human clinical studies — not just in-vitro or animal data.
Real Doses
Every ingredient appears at its studied dose, never the minimum to make the label.
Total Transparency
Active ingredients with exact amounts. No proprietary blends that hide what is inside.
Key Ingredients
The ingredients that
really work.
NAD+ Precursor
Nicotinamide Riboside (NR)
The most studied NAD+ precursor. Sinclair Lab research at Harvard shows NR raises NAD+ significantly more than standard niacin, with better tolerability.
Ref: Rajman et al., Cell Metabolism 2018
Clinical claim
+60% NAD+ in 8 weeks in human clinical studiesSenolytic
Quercetin Phytosome®
A patented form of quercetin bound to phospholipids for maximum intestinal absorption. Acts as a senolytic, clearing senescent cells that accelerate tissue aging.
Ref: Riva et al., Minerva Gastroenterologica 2019
Clinical claim
20× better absorption than standard quercetinMetabolic Activator
Berberine HCl
A plant alkaloid that activates the AMPK pathway — the same mechanism as metformin — to improve insulin sensitivity and regulate glucose.
Ref: Yin et al., Metabolism 2008
Clinical claim
Comparable to metformin for glucose controlAdaptogen
Ashwagandha KSM-66®
The ashwagandha extract with the strongest clinical evidence. 8 randomized double-blind studies show significant reductions in cortisol and anxiety.
Ref: Chandrasekhar et al., Indian J. Psych. Medicine 2012
Clinical claim
-27% cortisol in double-blind studies
