Pine bark extract is a dark red brown powder. Pine bark extract is a kind of substance extracted from pine bark. Pine bark peeled from trees is collected, flattened and extracted. It contains a large number of compounds called OPCS (procyanidins oligomers).OPCS have been found in many plants since the French scientist Dr. Jack maskelley isolated OPCS from peanut shells in 1947. In a large number of studies, it has been proved that OPCS are effective antioxidants with no toxicity, mutagenicity, carcinogenicity and side effects. It is very safe to use. Pine bark has been proved to be a new source of OPCS. There is no difference in quality and function of OPCS extracted from pine bark, but there are some slight differences in appearance.
