The Science of SIRT1

Inside every cell is a guardian protein called sirtuin 1 (SIRT1), short for Silent Information Regulator. It helps decide which parts of your DNA stay quiet and which stay active, helping cells adapt to stress, maintain energy efficiency, and resist the effects of aging.

Commonly known as the \"longevity switch,\" SIRT1 is involved in DNA repair, the removal of damaged cellular components, and the optimization of energy use. As we age, SIRT1 activity naturally declines due to factors such as oxidative stress, poor diet, disrupted sleep, and environmental challenges. This reduction is linked to diminished cellular resilience and many of the classic signs of aging.

The good news is that certain food compounds can help support SIRT1 function. Plant-derived polyphenols such as resveratrol (from red grapes) and pterostilbene (from blueberries) are among the best-studied for their ability to activate SIRT1 and promote healthy cellular aging. These compounds mimic calorie restriction at the molecular level, helping to reactivate SIRT1 and restore youthful gene expression patterns. By boosting SIRT1 activity, they help shift cells into a protective, repair-focused state, supporting the body’s natural defenses as we age.*^1-7

Why Resveratrol + Pterostilbene Work Better Together

Resveratrol is well-known for supporting SIRT1, but the body clears it fast. The liver converts most of it into inactive metabolites within minutes. Blood levels fall quickly, so only a limited amount reaches cells. The effect on SIRT1 is meaningful, yet short-lived.*^1-3,5-7

Pterostilbene shifts the profile. It is a close relative of resveratrol with two methyl groups that improve its performance.

Up to 4× higher oral bioavailability*
Greater lipophilicity for superior cellular penetration*
Significantly longer half-life in the body (up to 7× longer than resveratrol)*^4,14-16\n

When used together in a balanced ratio, the two ingredients work in sequence. Resveratrol supports a fast SIRT1 response. Pterostilbene keeps that response active for a longer period due to its greater stability. This provides steadier sirtuin pathway support than resveratrol alone.*^1-7,14-16

A Word from our Chief Science Officer

\"Resveratrol brought SIRT1 into the spotlight, but bioavailability has always limited its potential. By combining it with pterostilbene, we’re matching kinetics with biology — ensuring both rapid activation and sustained support of this key longevity pathway.\"

Ingredient Info
