 Resveratrol

Resveratrol is a powerful antioxidant that is produced by various plants to protect against environmental stresses. Perhaps the most notable producer of Resveratrol is the grapevine, which produces large amounts of Resveratrol in the skins of grapes to protect against fungal diseases and sun damage. It is therefore no surprise that wine may prolong life and fight age-related diseases such as Alzheimer and heart disease.  Also recent studies indicate that Resveratrol has promising therapeutic activity in various cancers, including breast, prostate, and neuroblastoma.  Resveratrol supplements come in various forms (mainly pills, tablets) and are becoming extremely popular due to positive medical research studies, exposure on TV shows like 60 minutes and Barbara Walters Special that Resveratrol based drugs are in development by big pharma.
