Resveratrol / Pterostilbene
Evidence: ★★☆☆☆ · Status: OTC Supplement
In plain English
The "red wine molecule" and its more absorbable cousin flip on the same longevity genes (sirtuins) that fasting does. Human results have been underwhelming for resveratrol (poor absorption); pterostilbene absorbs much better.
How it works
Polyphenol SIRT1 activators (sirtuin pathway, overlaps caloric-restriction signalling). Pterostilbene is the dimethylated form — far better bioavailability and half-life.
Molecular target & official sources
SIRT1 (NCBI Gene) · Resveratrol (PubChem CID 445154)
Protocol
Pterostilbene 100–250 mg; often paired with NMN/NR.
Bottom line
Weak human evidence; pterostilbene the better-absorbed choice.
Helps with: Live Longer
Stacks with
Shares a pathway — often paired with: NMN / NR (NAD⁺ precursors), Niacin / NADH (Vitamin B3).
Availability & where to buy
Available over the counter. Widely available OTC — e.g. iHerb (ships worldwide); in Singapore also Guardian, Watsons, GNC, Shopee / Lazada. Look for a third-party-tested / GMP mark and check the dose per serving.
