After years of experimenting with animals, American scientists have discovered that, a fragrant fragrance called "styrene" hydrocarbon, a derivative of resveratrol, extractedfrom blueberriesand grapes inhibits an enzyme called "P450 cytochrome," which activates chemical carcinogens and lowers LDL cholesterol. It has the function of preventing cancer and heart disease.

How to take it?

Its supplementation for the purpose of aiding glucose and lipid metabolism tends to be around 20- 40mg/kg oral ingestion in rats, which is an estimated human dosage range of:

Pterostilbene to take


●215-430mg for a 150lb person

●290-580mg for a 200lb person

●365-730mg for a 250lb person


Possible anxiolytic properties of pterostilbene are seen at 1-2mg/kg in mice, which is an estimated human dose of:

●5.5-11mg for a 150lb person

● 7.3-14.5mg for a 200lb person

●9-18mg for a 250lb person



This is notable as 5-10mg/kg in these mice (slightly over double the dose) has failed to have the same anxiolytic effects, suggesting a bell-curve that may favor lower dosages such as is found in food consumption rather than higher dosages from supplementation.

Limited human studies have used either 50mg twice a day or 125mg twice a day, and the addition of Grape Seed Extract(100mg at both dosing times) with the low dose may mitigate some adverse effects on cholesterol seen with it in isolation.
