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 (T1 Preferred) has a bioavailability rating of high (S1 — best tier). Typical dose range: not yet documented in our database.

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 T1 Preferred in the FormulaForge formulary — our top recommendation for Pterostilbene. It carries a bioavailability rating of high (S1 — best tier), meaning more of the active compound reaches your tissues per dose unit compared to lower-tier forms.

When choosing a Pterostilbene supplement, look for the S1 (best absorption) bioavailability tier on the label or formulary listing. T1 Preferred forms have the strongest research-backed evidence for efficient absorption.
