Some also promote it as a weight loss aid, but these claims are unfounded. 

Green tea extract supplements can vary in caffeine content. The above listing is for the NOW brand pictured. 

Some brands also add more EGCg and/or use decaffeinated tea leafs, so always check the label of the brand you choose.
