Green Tea Supplementation: Current Research, Literature Gaps, and Product Safety

This review broadly addresses the impacts of green tea (GT) and its extracts in a number of clinically-important areas, as listed below. It focuses on the available human research, and randomized, controlled trials, where possible. GT’s effects are not well established, due to the prevalence of conflicting data. It does appear that if GT is to have a positive effect on these outcomes, it likely needs to be in combination with caffeine.
