Epicatechin gallate is primarily known for its strong antioxidant properties, making it valuable in health and wellness applications. It supports cellular protection by neutralizing free radicals, which may reduce oxidative stress linked to chronic diseases. Research suggests it plays a role in promoting cardiovascular health by helping to maintain healthy blood vessel function, reducing inflammation, and lowering levels of bad cholesterol.

It is also studied for its potential in metabolic health, showing effects that may support glucose regulation and insulin sensitivity. Preliminary research indicates it may inhibit the growth of certain cancer cells, such as those in colon and breast cancers.

In skincare, epicatechin gallate is used in anti-aging formulations due to its ability to protect skin from oxidative damage and UV-induced stress, helping preserve collagen and improve skin elasticity. Its anti-inflammatory properties further aid in reducing wrinkles and sun damage.

Additionally, it contributes to antimicrobial activity, making it useful in oral care products for supporting gum health and reducing harmful bacteria. Its presence in green tea extracts makes it a key component in dietary supplements, food, and beverages aimed at overall health and longevity.
