Resveratrol in blueberries

Pterostilbene is an active constituent of blueberries and a natural methoxylated analogue of resveratrol.  Resveratrol has three analogues: pterostilbene, piceatannol and resveratrol trimethyl ether.

Resveratrol (trans-3,4’,5-trihydroxystilbene) in blueberries has been demonstrated not only to be potent antioxidant (~ 20-50 times more effective than vitamin C) but also to act synergistically with vitamin C, enhancing the effects of each.

It possesses significant anti-inflammatory and antioxidant properties that may benefit bone health. Resveratrol is the most extensively investigated for its osteogenic action in bone formation as well as bone resorption.

Resveratrol also has been demonstrated to have an anti-clotting effect that prevents the formation of thrombi (blood clots) that may block vessels and cause heart attacks and stroke.

Research in 1997 reported how resveratrol can inhabit the start of carcinogenesis, stopping cancer progression at its initial stages (Science. 1997 Jan 10;275(5297):218-20).
