Summary

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.

Pharmacokinetics

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 is 67%-94%, and its half-life has been published to be between 78 minutes and 104 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.

Pterostilbene Dosage

 The data collected from rat studies suggest a dose of 50–100 mg of pterostilbene 2x/day, similar to the dosage of resveratrol.

In wine

While resveratrol has been touted for its heart healthy benefits, pterostilbene is not found in wine despite darker grapes having the highest concentrations among the fruit. The reason believed is that it is unstable in light and air.

Toxicity

Pterostilbene is not known to be toxic to humans. There is some anecdotal evidence that doses of 200-250mg or more at once may induce temporary hypoglycemia in normal individuals.
