Grape Seed Extract OPC95

Details:

Grape seed Extract Proanthocyanidins/OPC 95%
Part Used:seed

Grape seed extract is a class of polyphenols extracted and isolated from grape seeds, mainly composed of polyphenols such as proanthocyanidins, catechins, epicatechins, gallic acid, and epicatechin gallate. Grape seed extract is a pure natural substance, and it is one of the most efficient antioxidants from plant sources found so far. Tests show that its antioxidant effect is 30 to 50 times that of vitamin C and vitamin E.

1.Powerful Antioxidant Activity
Proanthocyanidins are among the most potent antioxidants. They can scavenge free radicals such as superoxide anion radicals, hydroxyl radicals, and lipid peroxyl radicals more effectively than vitamins C and E. Free radicals are generated during normal cellular metabolism, exposure to environmental factors like ultraviolet radiation and pollution. By neutralizing these free radicals, proanthocyanidins help prevent oxidative damage to cells, including damage to DNA, lipids, and proteins.
For example, in the skin, proanthocyanidins can prevent the breakdown of collagen and elastin fibers, which are essential for maintaining skin elasticity and firmness. This antioxidant property also helps in reducing the signs of aging such as wrinkles and fine lines.
2.Cardiovascular Protection
Proanthocyanidins have beneficial effects on the cardiovascular system. They can inhibit the oxidation of low - density lipoprotein (LDL) cholesterol. Oxidized LDL is a key factor in the development of atherosclerosis. By preventing its oxidation, proanthocyanidins reduce the risk of plaque formation in the arteries.
They also have anti - platelet aggregation properties. Platelet aggregation can lead to the formation of blood clots, which can cause heart attacks and strokes. Proanthocyanidins help keep the blood vessels clear and improve blood flow by reducing the likelihood of clot formation.
3.Anti - Inflammatory Effects
Proanthocyanidins can modulate the body's inflammatory response. They inhibit the production and release of pro - inflammatory cytokines such as interleukin - 1β (IL - 1β), interleukin - 6 (IL - 6), and tumor necrosis factor - α (TNF - α). These cytokines play a central role in various inflammatory conditions, including arthritis, inflammatory bowel disease, and other chronic inflammatory disorders.
By reducing inflammation, proanthocyanidins can help alleviate pain and swelling associated with these conditions and may also contribute to the overall improvement of the body's immune function.
4.Vision Protection
Proanthocyanidins are beneficial for eye health. They can protect the retina from damage caused by oxidative stress and high - energy light such as blue light. The retina is a highly metabolically active tissue and is vulnerable to free - radical - induced damage. Proanthocyanidins can cross the blood - retinal barrier and provide antioxidant protection to the retinal cells.
They also have a role in improving ocular microcirculation, which is important for maintaining normal vision and preventing eye diseases such as macular degeneration and diabetic retinopathy.

1.Nutraceuticals and Dietary Supplements
Proanthocyanidins - rich grape seed extracts are widely used in the nutraceutical industry. They are formulated into capsules, tablets, and softgels as dietary supplements. These supplements are often promoted for their antioxidant and anti - aging benefits. Consumers take them to support overall health, boost the immune system, and improve skin health.
2.Cosmetics and Skincare
In the cosmetics and skincare industry, proanthocyanidins are used in a variety of products. They are added to creams, lotions, serums, and masks. Their antioxidant and anti - inflammatory properties make them ideal for anti - aging skincare products. They can improve skin texture, reduce redness, and enhance skin's natural glow.
