The bioactive form on which research focuses is trans-resveratrol.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eIn 2003, resveratrol made world news when David Sinclair (Harvard) and his team reported that the compound activates the SIRT1 protein — a 'longevity protein' that regulates DNA repair and mitochondrial function, among other things. Animal research showed that resveratrol supplementation extended the lifespan of yeast, worms and mice, particularly under calorie restriction. That launched the 'longevity supplement' niche and made resveratrol one of the best-known names in anti-ageing.\u003c\/p\u003e\n\u003cp\u003eIn practice, things are more complicated. In higher mammals — including humans — the effect is less clear-cut. Resveratrol has low bioavailability (it is rapidly metabolised in the liver), which makes doses of hundreds of milligrams per day necessary to reach plasma levels that correspond to the cell culture studies. Pterostilbene — a natural variant with two extra methyl groups — has higher bioavailability and is often positioned as 'next-generation resveratrol'.\u003c\/p\u003e\n\u003cp\u003eFor those who take the longevity theme seriously, resveratrol is usually part of a broader stack: in combination with quercetin (a synergistic polyphenol), pterostilbene, NAD+ precursors (NMN or NR) and spermidine.
