How to Choose

Understanding EGCG: The Science Behind the Supplement

EGCG, the principal catechin polyphenol found in green tea, has been extensively studied in peer-reviewed research for its potential to support metabolic function, promote cardiovascular wellness, and deliver powerful antioxidant protection at the cellular level. Unlike lower-potency green tea supplements, concentrated EGCG formulations deliver therapeutic doses typically ranging from 300-1000mg per serving, ensuring sufficient bioavailability for meaningful health benefits. The UK's regulatory framework, governed by the Food Standards Agency and supported by Natural England guidelines, ensures that all featured supplements meet stringent safety and quality benchmarks.

EGCG concentration levels significantly impact efficacy—premium formulations typically contain 50-90% EGCG compared to standard extracts at 25-40%

Bioavailability enhancement through standardised extracts and complementary ingredients optimises absorption and utilisation within the body

Third-party testing by accredited laboratories confirms potency claims and screens for contaminants, heavy metals, and microbial pathogens

Sustainable sourcing from certified tea plantations supports environmental stewardship whilst maintaining nutritional integrity

Storage conditions and packaging quality directly influence shelf stability and preservation of active compounds over extended periods
