What is Green Tea Extract?
Green tea extract is a concentrated form of the bioactive compounds found in green tea (Camellia sinensis). The star compound is epigallocatechin gallate (EGCG), a catechin polyphenol that accounts for most of green tea's researched health benefits. A single capsule can deliver the equivalent of several cups of green tea.
EGCG: The Key Catechin
EGCG is one of the most potent natural antioxidants studied. It scavenges free radicals, chelates metal ions, and modulates cell signaling pathways. EGCG also crosses the blood-brain barrier, providing neuroprotective benefits that most antioxidants cannot.
Metabolism and Thermogenesis
Green tea extract is one of the few supplements with genuine evidence for supporting metabolic rate. EGCG inhibits catechol-O-methyltransferase (COMT), an enzyme that breaks down norepinephrine, thereby prolonging thermogenic signaling. Combined with caffeine, it can increase 24-hour energy expenditure by 4-5%.
Cardiovascular Support
Regular green tea consumption is associated with reduced cardiovascular risk in epidemiological studies. EGCG supports healthy cholesterol profiles by reducing LDL oxidation, improves endothelial function, and promotes healthy blood pressure.
Brain Health
EGCG's ability to cross the blood-brain barrier makes it valuable for cognitive support. It promotes neuroplasticity, protects neurons from oxidative damage, and may support healthy brain aging. The combination of EGCG and L-theanine (naturally present in tea) provides calm, focused alertness.
Dosage and Timing
Standardized extracts typically provide 50-98% polyphenols with 45-60% EGCG. Take with food to reduce the rare risk of liver sensitivity. Decaffeinated extracts are available for those sensitive to caffeine.
