Data definition. Matched records include all indexed medical endpoints for this intervention — not only longevity. Longevity-relevant records are screened separately and cited in the evidence summary below. Counts are matched-record volumes, not de-duplicated trials and not efficacy claims.

Origin & tradition

Not traditional as an isolate; pterostilbene is found in blueberries and is studied as a resveratrol analog.

Why longevity buyers care

Key active: Pterostilbene (methylated stilbene).

Pterostilbene is a sirtuin-activating, better-absorbed stilbene studied for metabolic and lipid endpoints, frequently combined with nicotinamide riboside in human trials.

Dosage guidance

How Pterostilbene is typically used

Typical dose
50–500 mg/day
Form
capsule
Timing
with meals

Pterostilbene is a methylated analogue of resveratrol with ~80% oral bioavailability vs ~1% for resveratrol. At higher doses (>250mg/day), some studies show LDL increases — monitor lipids. pTeroPure is a common branded form.
