What is Grape Seed Extract?
Grape Seed Extract is a natural ingredient extracted from grape seeds. Grape seeds are the seeds contained in grape fruit. The main component of grape seed extract is grape polyphenols, which are nutrients extracted from grape seeds. It includes several different forms of anthocyanin precursors, and its mixture is oligomeric proanthocyanidins, also known as proanthocyanidins, and the English abbreviation is OPC (Oligomeric Proantho Cyanidins). Proanthocyanidin is a kind of bioflavonoid with special molecular structure. It is very water-soluble, easy to absorb in the body, quick to act, and has a long-lasting effect. It is a kind of high-efficiency natural antioxidant.
As a powerful antioxidant, proanthocyanidins can prevent free radicals such as reactive oxygen species, protecting your body from free radical damage caused by factors such as sun exposure, pollution and stress. A standardized extract of grape seed has also been shown to have positive effects in treating a variety of health problems associated with free radical damage.
