Product Introduction

Green Tea Extract EGCG Powder White to Off‑White Fine Powder Close Up

EGCG is a naturally occurring flavan‑3‑ol polyphenol with potent hydrogen‑donating and electron‑transferring antioxidant activity. It directly neutralizes superoxide, hydroxyl, and lipid peroxyl radicals, while chelating redox‑active transition metals to suppress Fenton‑type oxidation. At the cellular level, EGCG upregulates endogenous antioxidant enzymes (e.g., SOD, catalase, GSH‑Px) and inhibits pro‑oxidant enzymes such as lipoxygenase and cyclooxygenase.

In metabolic pathways, EGCG activates AMPK signaling to enhance fatty acid oxidation and mitochondrial energy expenditure, supporting healthy body composition. For cardiovascular function, it inhibits LDL oxidation, improves endothelial vasodilation via eNOS activation, and helps maintain normal lipid profiles. In dermal applications, EGCG penetrates the epidermis to reduce UV‑induced reactive oxygen species, attenuate matrix metalloproteinase (MMP) expression, and preserve collagen and elastin integrity, thereby moderating photoaging responses including wrinkle formation and hyperpigmentation.
