Epigallocatechin gallate
Epigallocatechin gallate (EGCG) is the principal catechin in tea from Camellia sinensis, the most consumed beverage worldwide (after water). Depending on brew time and temperature, a single cup of green tea may contain 100-200 mg EGCG. To control the dose of EGCG administered in experimental studies, green tea solids (GTS) or capsules of green tea extract standardized to EGCG content are often employed. However, there is considerable variability in the EGCG content of commercially available dietary supplements, ranging from 12-143\\\\\\\\% of the tablet or capsule weight. While standardizing tea preparations to EGCG or using highly purified EGCG for research presents an important strategy for the conduct of precise studies as well as the ability to replicate experiments, it is worth noting this approach limits the potential contributions and possible synergy with other bioactive tea ingredients, including caffeine and other flavonoids. Human studies of the bioavailability of green tea catechins reveal these compounds to be poorly absorbed, with <0.1\\\\\\\\% of ingested catechins appearing in blood. Most ingested EGCG is rapidly cleared from blood with an elimination half-life of {approx}3 h and preferentially excreted via bile to the colon. The growing interest in the role of EGCG in health promotion and disease prevention is reflected by an exponential growth of research publications in this field.
