Overall, Iaso Tea is a good detox tea that comes with all the benefits of detox and having a clean colon and improved digestion. However, user reviews reveal that the claims of weight loss are stretched too far. This tea is a basic form of a detox really and there are plenty of other products that can do the same trick. Besides, since it contains laxatives, people might experience certain side effects including diarrhea and constipation. Regarding weight loss, to REALLY shed pounds with Iaso tea, you will have to drink lots of tea, to take in its superfoods ingredients in huge quantities. Drinking a lot of tea would cause you to have lots of energy and raise your metabolism up during the day and will cause appetite suppression. But, this will come with very serious side effects like feeling jittery, raised blood pressure levels, etc. Basically all those side effects of drinking excess tea. We recommend Smoothie Diet for weight loss, over Iaso tea. Smoothie Diet is a sustainable way to lose weight with healthy superfoods, by making them a part of your diet. That should be a lifelong strategy, unlike fad diets like tea detox which do more harm than good. If you are looking for a "green tea" based thermogenic fat loss product, we recommend Instant Knockout.
