Just like the human body responds to an injury with a predictable inflammatory response and to the attacks of pathogens by producing antibodies, several plants produce resveratrol in response to plant injury and to protect the plant against fungal diseases and sun damage.
Sources of Resveratrol
Though resveratrol is found in blueberries, raspberries, mulberries, peanuts, and so on, the important sources for the highest resveratrol content are red grape skins and red wine that is fermented with the grape skins longer than white wine. Resveratrol is also found in the seeds and pomace of grapes. The grapes grown in humid environments are tend to produce more resveratrol than the grapes grown in arid environments in order to fight the fungus that damages the plant.
Functioning of Resveratrol
Since resveratrol is a powerful antioxidant with great potential like Palmitoylethanolamide , it helps in preventing cell damage caused by free radicals that are produced by pollution, sunlight, and the natural burning of fat in our bodies that can lead to cancer, aging and brain degeneration. Thus, it protects the DNA of a cell.
Resveratrol Supplements are considered as a dietary supplement which generally is safe for healthy people to take. But, there are no demonstrative studies conducted for appropriate doses, uses, long-term safety, and effectiveness.
The supplement may widely vary in the amount and purity. Micronized resveratrol in the form of pill and powder is widely available. It is not absorbed well orally because of low systemic bioavailability. But the absorption is generally increased and the average size of the compound is greatly reduced in the process of micronization. There are also other forms of resveratrol like in the form of solution and as transdermal patches.
