Unlocks the full health benefits of Pterostilbene

CIRCE Scientific presents PTEROVITA, a patented cocrystal of Pterostilbene and Picolinic acid that synergistically improves solubility and enhances the bioavailability of Pterostilbene. This unique combination scientifically enhances the natural health benefits of both Picolinic acid and Pterostilbene.

Why ?

Pterostilbene has demonstrated the potential to improve human health when reaching the cells of specific tissues, but its efficacy is limited by its low bioavailability.

With a bioavailability of 99%, PTEROVITA significantly enhances the absorption and effectiveness of Pterostilbene in the body.

PTEROVITA improves the properties of pterostilbene by enhancing its dissolution rate more than 35-fold, elevating its solubility in diverse media by 2 to 5 times, and increasing its in vivo bioavailability by a factor of ten.

CIRCE Scientific comparative bioavailability study:

20mg/kg of PTEROVITA, which contains 68% pterostilbene, achieves 9.9 times higher levels in the blood (measured as pterostilbene AUC/dose) than 20mg/kg of regular pterostilbene.

This results in improved activity and significant dose reduction (a 1/8th dose is sufficient to achieve equivalent blood levels due to non-linear pharmacokinetics).

When compared to other published studies on pterostilbene and resveratrol bioavailability, PTEROVITA demonstrates significantly higher bioavailability based on Cmax, making it the most bioavailable stilbene currently available on the market.


PTEROVITA is a patented cocrystal of Picolinic acid and Pterostilbene, the synergistic effects of these two ingredients work together to significantly enhance the bioavailability of Pterostilbene, unlocking the natural health benefits of both compounds.

A cocrystal is a new crystalline form that combines two or more different molecules to create a structure with improved physicochemical properties compared to the individual components.

Picolinic Acid

Picolinic acid is a naturally occurring organic compound that is produced in the human body and is also found in some foods such as spinach, mushrooms, and soybeans. It is a derivative of the amino acid tryptophan and is known to play an important role in the uptake and metabolism of essential trace minerals like zinc in the body.


Pterostilbene is a naturally occurring stilbenoid, which is predominantly found in blueberries and other natural sources. This compound is chemically related to resveratrol and shares many of its antioxidant properties.

Pterostilbene has gained recognition for its powerful antioxidant and anti-inflammatory properties, as well as its ability to activate sirtuins, which are enzymes linked to longevity. As a result, it is often used in functional foods, beverages, and supplements to provide health benefits
