The grape seed extract is a substance extracted from the common wine grape (Vitis vinifera). This extract is often sold as a supplement, and it comes in different forms such as liquid, tablet, or capsule. Numerous previous studies have shown that grape seed extract contains antioxidants and various other compounds that may benefit health.
The grape seed extract is a class of polyphenols extracted and isolated from grape seeds, mainly composed of polyphenols such as proanthocyanidins and catechins. Grape Seed Extract is a purely natural substance and one of the most potent antioxidants found in herbal extracts to date. Tests have shown that the antioxidant effect of grape seed extract is 30 to 50 times that of vitamin C and vitamin E. Proanthocyanidins have extremely strong activity, and their ability to capture free radicals in the aqueous phase is 2 to 7 times that of general antioxidants, such as more than twice the activity of α-tocopherol.
So from which aspects to choose products containing grape seed extract?
1. OPC content
The human body cannot absorb a high unit of OPC. Higher OPC is not only a waste but even a burden to the human body. The optimal intake of grape seeds for the human body: OPC 200mg/day.
2. Blue hat sign
The blue hat sign is a formal approval mark, which proves that the product is a healthcare product that meets the national production standards, so choose this sign on the packaging of grape seed extract products.
3. Compound ingredients
Grape seed capsules are not as pure as possible. The combination of grape seed and soybean lecithin to form a composite ingredient is better than taking pure grape seed capsules. The combination of grape seed and soybean lecithin can maximize the effect of antioxidants, improve the effect of beauty and skin rejuvenation, and can protect the activity of OPC itself.
