Iaso Tea claims to detox your body to help with losing weight more efficiently and clearing your body of harmful toxins. Their claims of purifying the blood and regulating bowel function also go into this category as well. The claim also seems a bit bold to us since the human body has it’s very own way of breaking down and removing these toxins such as our liver, kidneys, and skin. There isn’t much research done to prove that our body needs extra help with these functions, which makes it a bit useless.
