What is Grape Seed Extract?

The grape seed extract is a high-efficiency natural antioxidant ingredient extracted from grape seeds. Catechins and procyanidins make up the majority of the polyphenols found in grape seeds. Catechin compounds include catechins, epicatechins, and their gallates, which are the main monomers in grape seeds. They are the building block of procyanidin oligomers and polymers and are the most active substances found in nature to resist oxidation and scavenge free radicals. Grape seed extract can effectively remove excess free radicals in the human body, and has super anti-aging and immune-enhancing effects. Its main functions include anti-inflammatory, anti-histamine, anti-allergic, anti-allergen, anti-oxidation, anti-fatigue, enhancing physical fitness, improving sub-health state, anti-aging, beauty, promoting blood circulation, etc.

Proanthocyanidins have super antioxidant activity and can inhibit the synthesis and release of inflammatory factors such as histamine, serotonin, prostaglandins, and leukotrienes, and inhibit the release of granules from basophils and mast cells. It also inhibits histamine decarboxylase activity and limits the action of hyaluronidase.

3. Anti-atherosclerotic
