EGCG (Epigallocatechin Gallate) is a type of polyphenol antioxidant found in a variety of tea leaves, particularly green tea. It is the most abundant catechin found in black and green tea leaves, although tea leaves contain other catechins too, such as epicatechin, gallocatechin, and gallate derivatives. EGCG is also found in small amounts in other foods, such as fruits (cranberries, strawberries, blackberries, kiwis, cherries, pears, peaches, apples, and avocados), nuts (pecans, pistachios, and hazelnuts), and some supplements.

EGCG has been shown to have free radical-scavenging abilities and other beneficial effects that help protect cells and tissues throughout the body. Test-tube, animal, and a few human studies indicate that EGCG provides numerous health benefits, including reduced inflammation, weight loss, and improved heart and brain health. In fact, the numerous health benefits associated with drinking green tea are typically credited to its EGCG content.

Green tea extract is made from dried green tea leaves, so it does contain EGCG, along with caffeine and other antioxidants. To increase your intake of this compound, the top EGCG foods and beverages to include in your diet are green tea (which has slightly higher amounts of catechins than black tea), black tea, white tea, and oolong tea. You can help increase the EGCG concentration of your tea by steeping it in boiling water (not just hot water) and letting it sit for a full 10 minutes before removing the leaves.

In conclusion, EGCG is a beneficial plant compound called a polyphenol that is found in green tea and other foods. It has numerous health benefits and is a powerful antioxidant that helps protect cells and tissues throughout the body.
