EGCG (Epigallocatechin gallate)

What is EGCG?

EGCG, or epigallocatechin gallate, is the most abundant catechin in green tea, making up about 50-80% of its total catechins. It’s the molecule behind green tea’s reputation as a health drink, and it’s been studied for its powerful antioxidant, anti-inflammatory, and metabolic effects.

EGCG Sources

Green tea (Camellia sinensis) is the primary natural source, but EGCG is also found in smaller amounts in other teas and some fruits. For commercial production, we extract EGCG from green tea leaves using a green solvent process, then purify it to 98% purity by HPLC.

EGCG Absorption and Bioavailability

EGCG is known for its poor oral bioavailability, which is why formulators often pair it with piperine or use liposomal delivery systems. But even at moderate doses, it shows measurable plasma levels and biological activity. Our 98% pure EGCG is micronized to enhance absorption, and we provide full COA data on dissolution and particle size.

Safety of EGCG

EGCG is generally recognized as safe (GRAS) at typical supplement doses (up to 800 mg/day). It’s water-soluble, so excess is excreted, but high doses on an empty stomach can cause mild GI upset. Our product is manufactured under GMP, with heavy metals and residual solvents tested to meet international standards.

EGCG in Supplements

You’ll find EGCG in weight loss stacks, antioxidant blends, and cognitive health formulas. Studies point to its role in boosting metabolism, supporting fat oxidation, and protecting neurons from oxidative stress. We supply this powder to supplement brands, beverage companies, and cosmetic manufacturers — every batch ships with a full COA, from 1 kg samples to bulk drums, worldwide.
