Resveratrol vs Pterostilbene

Resveratrol vs its methylated cousin — bioavailability, dose, and what the human trials actually show.

Reviewed by Read Off Label · How we grade

Bottom line

On the composite score, Resveratrol (B-, 6.2/10) edges out Pterostilbene (C-, 4.5/10) — but the right pick depends on the specific outcome you're optimising for.

Resveratrol

B- 6.2/10

Evidence: Weak-Moderate (4.5/10)
Benefit: Low-Med (3.5/10)
Risk: Low (9/10 safety)
Legality: OTC
Dose: 150-500 mg/day trans-resveratrol; ideally micronized or with fat for absorption
Class: Supplement
Last reviewed: Jun 8, 2026

Read Off Label grades Resveratrol as B- (6.2/10) based on weak-moderate evidence, low-med benefit magnitude, and a low-risk safety profile.

Oft-cited as foundational longevity compound but human RCTs largely unimpressive.

Typical use: 150-500 mg/day trans-resveratrol; ideally micronized or with fat for absorption — OTC.

What it is

Oft-cited as foundational longevity compound but human RCTs largely unimpressive. Poor bioavailability (~1%). Metabolites may be active. 2025 meta-analysis: no significant SIRT1 effect in humans. Popularity persists despite modest signals.

Mechanism

Trans-resveratrol proposed SIRT1 activator (debated — likely indirect); AMPK activation; anti-inflammatory; vascular endothelial effects; poor oral bioavailability

Pterostilbene

C- 4.5/10

Evidence: Weak-Preclinical (2.5/10)
Benefit: Low-Med / Varies (3.5/10)
Risk: Low-Med (LDL elevation reported) (7/10 safety)
Legality: OTC
Dose: 50-250 mg/day
Class: Supplement
Last reviewed: Jun 8, 2026

Read Off Label grades Pterostilbene as C- (4.5/10) based on weak-preclinical evidence, low-med / varies benefit magnitude, and a low-med-risk safety profile.

Paired with NR in EH301 trial — modest ALS functional improvement.

Typical use: 50-250 mg/day — OTC.

What it is

Paired with NR in EH301 trial — modest ALS functional improvement. Better absorbed than resveratrol in theory but limited direct head-to-head human data. Often combined with nicotinamide riboside (e.g., Basis, Niagen+).

Mechanism

Dimethylated resveratrol analog; better oral bioavailability (~80% vs 1%); SIRT1 activator; AMPK activator; anti-inflammatory
