Overview
Polyphenol from grapes activating longevity pathways. Sirtuin activator studied for cardiovascular and anti-aging benefits.
Compare Forms
4 formsDifferent chemical forms vary in absorption, side effects, and best use cases. Higher bioavailability scores indicate better absorption.
Trans-Resveratrol (โฅ98%)
HIGH 95The biologically active isomer โ what virtually all studies use
๐ก Poor oral bioavailability (~1-2%) โ pair with fat or piperine.
- โข Active isomer
- โข Most-studied form
- โข Reasonable cost
- โข Low absorption โ need higher doses
- โข Quickly metabolized in liver
๐ Look for โฅ98% trans-resveratrol on the label. Take with a fat-containing meal.
Resveratrol + Pterostilbene Combination
HIGH 100Combined with pterostilbene โ a methylated analog with much better bioavailability and longer half-life
๐ก Pterostilbene compensates for resveratrol's poor absorption (~80% vs ~1-2%).
- โข Synergistic action
- โข Pterostilbene's longer half-life
- โข More cellular signaling effect
- โข More expensive than plain resveratrol
- โข Still limited human longevity data
๐ Best practical combination for longevity protocols. Common ratios: 250 mg resv + 50 mg ptero.
Liposomal Resveratrol
HIGH 90Phospholipid-encapsulated for higher absorption
๐ก Several-fold higher than standard trans-resveratrol.
- โข Better absorption
- โข Lower effective dose needed
- โข Premium price
- โข Refrigeration often needed
๐ Worth it if you want high bioavailability without the pterostilbene combo.
Resveratrol Standardized from Japanese Knotweed
HIGH 85Most commercial resveratrol โ extracted from Polygonum cuspidatum root
๐ก Same as trans-resveratrol since it's the source.
- โข Reliable supply
- โข Lower cost than grape-derived
- โข Source matters less than purity โ check trans-isomer percentage
๐ Source isn't the issue; standardization is. Look for โฅ98% trans-resveratrol.
