Vitis vinifera L., grape vine, is a perennial, defoliating limber with a wooden often twisted stem which can reach a length of 30 meters, but it is usually cut back to 1-3 meters.
Grape seed extract contains a special class of water-soluble bioflavonoids called proanthocyanidin (OPC) which has been studied for a variety of health conditions. This is a phenolic chemical belonging in the larger group of plant phytochemicals. It belongs to a subgroup of tannins.
Vitis vinifera extract is well known for its antioxidant activity. Additionally, by nourishing blood vessel walls and performing other renewing functions, grape seed extract helps promote healthy blood pressure levels, heart health, and a proper inflammation response. Proanthocyanidins improve blood circulation and help strengthen blood vessels and cardiovascular system. It does this by stopping the breakdown of collagen. This reduces the risk of a heart attack and stroke. It may also have an antioxidant effect. This may lower the risk of certain cancers.
