Bulk Supplements Grape Seed Extract Powder Procyanidins
Procyanidins, also known as condensed tannins, condensed tannins, and proanthocyanidins, are polyphenolic compounds that can produce anthocyanins under thermal acid treatment. They are widely distributed and rich in natural plants, mainly found in grapes seeds, ginkgo leaves, lotus leaves, Japanese podocarpus, French maritime pine bark and other natural plants.
Proanthocyanidins are natural antioxidants with a variety of biological activities. Their strong ability to scavenge free radicals and inhibit lipid peroxidation are prerequisites for their wide application in cosmetics. Proanthocyanidins have a variety of effects when used in cosmetics, including anti-aging, whitening, sun protection, anti-wrinkle and moisturizing, etc., and have become the focus of research and development in the field of related cosmetics.
What Does Bulk Supplements Grape Seed Extract Do
Grape Seed Extract Procyanidins Benefits
Free Radical Scavenging And Antioxidant Activity
The antioxidant capacity of grape seed extract proanthocyanidins in the body is 20 times that of vitamin C and 50 times that of vitamin E. In in vitro antioxidant tests, the scavenging rate and total antioxidant capacity of proanthocyanidins against hydroxyl free radicals and DPPH free radicals within a certain dose range was significantly higher than that of vitamin C.
At the same time, it has the effect of increasing the activity of antioxidant enzymes. Superoxide dismutase, catalase and glutathione peroxidase are enzymes that play an antioxidant role. Proanthocyanidins can increase the activity of these three enzymes, thus enhance antioxidant effect.
Skin Whitening
Dark skin or dark spots are mainly caused by factors such as accumulation of melanin, skin oxidation, keratinocyte deposition, poor skin microcirculation, and accumulation of toxins in the body. Proanthocyanidins can reduce the o-phthaloquinone structure of melanin to a phenolic structure, causing the pigment to fade, and can also inhibit the activity of tyrosinase, a key enzyme for melanin synthesis.
Anti-glycation
The glycation reaction ultimately produces advanced glycation end products, or AGEs. The accumulation of AGEs in the intracellular and extracellular skin environment will cause the cross-linking and stiffening of collagen, elastin or fibronectin fibers, and increase the production of melanin, which is one of the culprits of human aging.
Studies have shown that the degree of protein non-enzymatic glycosylation is negatively correlated with the concentration of proanthocyanidins, and the effect of inhibiting the production of AGEs is much higher than that of AG at the same concentration.
Anti-wrinkle
Skin aging is mainly caused by the loss of collagen, the reduction of elastic fibers, and the thinning and atrophy of subcutaneous tissue.
Grape seed extract proanthocyanidins can react with collagen through hydrogen bonds, ionic bonds, covalent bonds, etc., thereby enhancing collagen activity. Studies have found that proanthocyanidin cross-linking can prevent collagenase from loosening the triple helix structure of collagen, thereby improving the resistance to enzymatic degradation and the stability of mechanical properties of collagen.
Sun Protection
Proanthocyanidins have strong absorption effect on ultraviolet (UV) 280nm. Topical application of grape seed proanthocyanidins can reduce Fas protein expression and increase Bcl-2 protein expression in skin after irradiation, bringing it close to normal skin values, indicating that grape seed proanthocyanidins can reduce sun damage to a certain extent.
Is It Good to Take Grape Seed Extract Everyday
Bulk supplements grape seed extract safe with few side effects. Dosages of around 300–800 mg per day for 8–16 weeks have been found to be safe and well tolerated in humans.
In terms of daily consumption, it is generally recommended to consult with a healthcare professional before taking any supplements, including grape seed extract. This is because supplements can interact with other medications or conditions, and may not be suitable for everyone.
