Doctor's Best Green Tea Phytosome Feat Supplement, 60 Count

The four major green tea catechins (EGCG, EGC, ECG, and EC) have different chemical structures, and thus are able to scavenge a variety of free radicals. Some clinical trials suggest that EGCG may have synergistic effects with other catechins, and that metabolic derivatives of EGCG and perhaps the other catechins may have potent bioactivity. Human trials suggest the green tea polyphenols help protect DNA by providing an extra source of dietary antioxidants. Researchers have proposed that the green tea catechins and their metabolic derivatives have antioxidant actions that are both direct (via scavenging radicals) and indirect (by influencing gene activity and up-regulating antioxidant enzymes) intense physical exercise generates reactive oxygen species (oxygen "free radicals") that can challenge the body's antioxidant defenses. In a recent randomized, double-blind, placebo-controlled trial of 35 healthy young men, 17 of them received green tea extract capsules containing 320 mg of polyphenols, while the remaining 18 received a placebo, both for 4 weeks. The men performed a short-term muscular endurance test twice-once before and once after the supplementation period. Supplementation with the extract resulted in a significant increase in total blood polyphenols both at rest and 5 minutes after the endurance test, compared to placebo. This polyphenol increase contributed to enhanced blood antioxidant status at rest, suggesting that the green tea catechins can help offset potential oxidative stress from intense exercise in untrained men.in another recent randomized, double blind, placebo controlled trial, 56 overweight participants received either green tea extract or a placebo with breakfast for 3 months. The extract was found to promote healthy metabolic function and a significant increase in total antioxidant status (signifying support against oxidative stress).
