Grape seed extract mainly includes proanthocyanidins, grape seed oil, resveratrol, vitamins, tannins, etc., all of which have beauty and health care effects. Proanthocyanidins have strong antioxidant ability, and its antioxidant effect is 50 times that of VE and 20 times that of VC. Grape seed proanthocyanidin extract has 85% bioavailability in the human body. Proanthocyanidins can inhibit the formation of peroxides caused by ultraviolet radiation on the skin; it can also inhibit the Maillard reaction, inhibit the formation of lipofuscin and age spots; it can also inhibit the activity of tyrosinase, which reduces the o-quinone structure of melanin to a phenolic structure, causing the pigment to fade. Therefore, proanthocyanidins have the effects of improving skin inflammation, preventing melanization, whitening skin, and anti-aging. Grape seed oil also contains a high mass fraction of VE, which can reach 360μg/g. VE can accelerate the removal of damaged cells and aging cells, protect regenerated cells and new cells, and maintain moisture, so as to delay skin aging. Grapeseed oil has some antioxidant and anti-aging effects.
Is grape seed extract water-soluble or fat-soluble?
The polyphenols in GSE are water-soluble, while proanthocyanidins are both water-soluble and fat-soluble. Therefore, the body absorbs polyphenols quickly, but proanthocyanidins are absorbed more slowly and stored in the body for a slightly longer time. What is the recommended daily intake of grape seed extract? Because grape seed extract is not considered an essential nutrient, no regulatory agency has established a recommended daily intake (RDA) for grape seed extract. However, clinical trials of the efficacy of grape seed extract have been conducted with doses as low as 150mg or as high as 2000mg per day. Can you absorb enough grape seed extract from food? It is virtually impossible to absorb enough grape seed extract from food. Since the average person does not eat grape seeds, it is necessary to consume grape seed extract in supplement form to obtain its benefits
Finally, grape seed extract (GSE) is a dietary supplement that is rich in antioxidants, including phenolic acids, anthocyanins, flavonoids, and oligomeric proanthocyanidin complexes (OPCs). Therefore, it is a potent source of antioxidants, especially proanthocyanidins. By supplementing with GSE, you will reap the benefits of better heart, brain, and skin health.
