Product Description

Pterostilbene is a stilbenoid chemically related to resveratrol and is found in blueberries and grapes. It belongs to the group of phytoalexins, agents produced by plants to fight infections. Based on animal studies it is thought to exhibit anti-cancer, anti-hypercholesterolemia, anti-hypertriglyceridemia properties, as well as fight off and reverse cognitive decline. It is believed that the compound also has anti-diabetic properties, but so far very little has been studied on this issue.
Pterostilbene is a double-methylated version of resveratrol exhibiting a higher bioavailability as it is more easily transported into the cell and more resistant to degradation and elimination. In rats, pterostilbene's oral availability was about *2%, and its half-life *7 minutes. Pterostilbene has anti -inflammatory, antineoplastic, and antioxidant actions via modulations of gene expression and enzyme activity. In plants the substance displays antifungal and antiviral activities. Focus of studies has been generally on the trans isomer of pterostilbene.
