Pterostilbene

Pterostilbene is a Specialty supplement available in 1 form.

Not all forms of Pterostilbene are equal. The form you choose determines how much Pterostilbene actually reaches your tissues, and the difference between the best and worst forms can be substantial. Pterostilbene is a natural dimethylated analogue of resveratrol with significantly superior oral bioavailability (~80% vs. ~20% for resveratrol) due to reduced hydroxyl groups limiting first-pass metabolism. As an S1-tier stilbene, research suggests pterostilbene promotes healthy cognitive function, antioxidant defense, and SIRT1 pathway activation more efficiently than resveratrol.

Pterostilbene Preferred (Preferred Form) has a bioavailability rating of high absorption.

Pterostilbene is a methylated analogue of resveratrol with 4x greater bioavailability and longer half-life. Research demonstrates superior sirtuin activation, AMPK activation, and antioxidant activity compared to resveratrol. Clinical studies support cardiovascular, cognitive, and metabolic health applications. It is the most bioavailable stilbene compound available.

Pterostilbene is classified as Preferred Form by FormulaForge — our top recommendation for Pterostilbene. It carries a bioavailability rating of high absorption, meaning more of the active compound reaches your tissues per dose unit compared to lower-rated forms.

When choosing a Pterostilbene supplement, read the label for the specific form name — that is what determines how much you actually absorb. Preferred Forms have the strongest research-backed evidence for efficient absorption.

Other forms may be appropriate depending on individual goals, cost considerations, and your healthcare provider’s guidance. The best form for you depends on your specific health needs.
