Pterostilbene (pronounced terro-still-bene) isolated from Pterocarpus marsupium is a beneficial dietary compound that is found in antioxidant-rich foods like blueberries, cranberries and grapes. In both human and animal studies, it has been shown to offer protection against many neurological, cardiovascular, metabolic and hematologic disorders. For example, pterostilbene benefits include protecting against memory loss, high cholesterol, high blood pressure levels and even certain types of cancer. As a methylated stilbene molecule, it has a similar structure to the antioxidant Resveratrol.
Pterostilbene and resveratrol both have the same role in the plant’s defense system. “Resveratrol is one of the main phytoalexins in grapes, pterostilbene in blueberries,” “The only difference between the two is the presence of two methoxy groups in pterostilbene (resveratrol has three hydroxyl groups, pterostilbene has one along with the two methoxys).
Pterostilbene and resveratrol share many of the same benefits, including fighting oxidative stress, but pterostilbene has been shown to have superior bioavailability. In other words, pterostilbene is believed to be absorbed and utilized by the body more easily than similar phytonutrients, which is one reason why it’s recently caught the attention of health researchers.
Pterostilbene is a stilbene molecule and dimethylated derivative of resveratrol, an antioxidant that helps fight free radical damage which contributes to the aging process.
Potential uses of pterostllbene:
»»» Fighting oxidative stress, it has strong antioxidant activity. This allows it to help prevent and treat various chronic diseases.
»»» As an antioxidant that helps fight free radical damage which contributes to the aging process.
»»» Helping to prevent cancer and tumor growth, especially breast and colon cancers.
»»» Protecting against neurological diseases, including memory loss and dementia.
»»» Fighting inflammation, the root cause of many diseases, and boosting the immune system.
»»» Protecting the heart and blood vessels.
»»» Naturally fighting bacterial and fungal infections of the skin.
»»» Helping to prevent diabetes, high cholesterol, high blood pressure and metabolic syndrome.
