Resveratrol is the modern day answer to health ailments especially which are age old. It is found in different types of plants. Some of these are forms of dietary supplements and herbal formulations in Asian folk medicine.
Resveratrol is present in foods including peanuts, blueberries, lingonberries, sparkleberries, cranberries, deerberries, partridgeberries, and bilberries. Resveratrol is found in most abundance, though, in the skin of grapes that are used to make red wine. Resveratrol is the best anti oxidant that can be naturally obtained.
It is one of the most volatile molecules and when exposed to oxygen, oxidizes and breaks down rapidly.
It is thus important for manufacturers to produce the Resveratrol supplements in an environment that preserves its potency. In addition, the delivery mechanism is very important as it will determine both the bioavailability of the Resveratrol content as well as the metabolization.
The Bioavailability of resveratrol in people is necessary and crucial since most of the studies on resveratrol have been done on cultured cells in pietre dishes in the lab which are exposed to resveratrol which has been unmetabolized and in concentrations that are usually ten to a hundred times in excess of the highest concentrations measured in human plasma after been orally consumed.
Even though the digestive tract cells are exposed to poorly metabolized resveratrol, research in humans suggests that other organs and cellular tissues are exposed mainly to metabolized resveratrol. Not much is understood about the biological activity of metabolized resveratrol , and it has not been conclusively determined if some cells are able to convert resveratrol metabolites back to resveratrol.
Therefore, ingesting resveratrol supplements that deliver a more effective bioactive resveratrol dose is an important factor in the manufacturing of these resveratrol products. There are several methods being utilized by the major resveratrol manufacturers to improve bio availability.
