Iaso tea claims to provide a boost in mental and physical energy as a result of all the “detoxifying” and “weight loss aid” effects. This is one of the more believable claims (along with natural weight loss) since the tea itself becomes a big motivator for people to be healthier. Not only is the tea packed full of healthy, antioxidant-packed ingredients, but as you start eating healthy and exercising consistently, you become more energized naturally.
