What is Pterostilbene?

Pterostilbene is a stilbenoid found in many natural sources, predominantly in blueberries.

It is chemically related to the more well-known resveratrol, but their differences make pterostilbene more bioavailable and with a longer half-life.

Pterostilbene is a potent antioxidant used in supplements due to its antioxidant, anti-inflammatory and sirtuin activation (longevity) properties.

Pterostilbene properties

Helps slow the aging process

Helps fight & prevent cancer

Boosts brain health & prevents Alzheimer’s

Reduces risk for heart disease

Helps regulate blood sugar & manage diabetes

Due to its structural characteristics, standard pterostilbene exhibits better bioavailability and half-life than resveratrol.

However pterostilbene’s oral bioavailability remains low, only 5-16% of the total intake, which lowers its biological effectiveness and forces its use being intra-peritoneal or intra-venous for its more powerful healthy uses.



A Highly Bioavailable


Through cocrystal engineering, CIRCE Scientific has developed a unique patented combination of pterostilbene and picolinic acid that improves pterostilbene’s bioavailability 10 times up to >99%, making it much more efficient than any form of pterostilbene in the market.

We commercialize the ingredients directly, in the form of improved raw material to food, supplement, cosmetic, feed, or pharmaceutical companies.
