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. 
The boldest claim that Iaso Tea provides is that the tea can make you lose five pounds in five days. There is no actual research that proves detox teas can make you lose that amount of weight in such a short amount of time. Nor is it likely that your body could do such a thing in a short amount of time. The harsh reality of that claim is that if you do see fast weight loss results, it will be water weight and not body mass being lost.

Iaso tea is not a magic bullet. In fact, it’s not even that special for weight loss. So how does it help sustained weight loss? The utlity of the tea is that it serves to replace unhealthy meal options. Instead of sugary drinks or snacks, the tea steps in as a replacement to curb hunger while also delivering a large payload of nutrients to help your body detox. This lowers your daily calorie intake and thus helps with weight loss. Over time, you’ll be able to break the sugar addiction you don’t know you even have, and phase out the unhealthy foods in your diet.

When keep consuming unhealthy food our body collect toxins that can't go our easily. Detox teas contain specific blends of natural ingredients which flush these toxins and chemicals we are consuming out of our vital organs. Those herbs are extremely effective for reducing cholesterol, body fat, improve digestive system and help our body losing weight.
There may be a lot of impressive results, reviews, and promising claims that Iaso tea really works and there may even some before and after pictures to really prove it to their customers. However, you can never know for sure if these reviews are entirely legitimate, and if the product really works for weight loss. As we have already gone over above, the Iaso Tea’s hefty claim of losing five pounds in five days guaranteed is just to good to be true. Most likely, any instant weight loss that is seen with the tea is the result of water weight loss and no actual body mass being lost. 
Iaso Tea claims to flush the harmful toxins out from the upper and lower intestines to provide several different benefits. However, the human body has its own ability to breakdown and remove these toxins from namely the liver, kidneys, and skin. This leads us to believe that the detox properties of this tea don’t do as much for our body’s as we may think, but the benefits still won’t hurt. 
Supports Restful Sleep. There are many natural ways that you can promote sleep in your daily life, such as changing your lifestyle and nutrition, but what most people don’t know is that hemp extract can help as well. Research suggests that the cannabidiol in hemp can promote restful sleep, even for those who struggle with sleep or have insomnia. CBD oil is well known to also assist with pain, stress, and anxiety, which can all be related to a poor sleep regimen or be effected by said things. 
I have experienced exactly the same. I bought Yogi Berry DeTox and after just the second day (one cup per day) I could not sleep a minute. It kept me up all night despite that there are no stimulants (e.g. caffeine) in this version of the tea, or at least none is indicated on the label. It seems that some of us just might be sensitive to some of the ingredients.
Not only does 310 Tea contain both green tea and oolong tea, the company includes the amounts of each ingredient on the label – which is very rare in this field. And according to one 2015 study, you have to consume between 600-900mg tea catechins per day in order to see weight loss benefits – which you easily get with just two cups of 310 Tea per day.5
_{Yogi Detox Tea is the top-selling tea in the natural industry, and contains a unique blend of different herbs and plant extracts. This tea claims to assist the body’s natural detoxification process in eliminating waste and promoting healthy, natural weight loss. While ingredients such as ginger root and sasparilla are commonly used in weight loss formulas, research shows that one would need to consume significant amounts of each of these extract to see even modest weight loss.}

I personally have benefited greatly by drinking weight loss tea. Also known as herbal slimming teas, not only are these easily available, they are super delicious and you really do not have to spend hours making them. Detox teas or teetox as they are popularly known, gently cleanse the system, kick-start slow or sluggish digestion and also help in burning fat.

Detox teas can aid weight loss by improving the metabolic rate and decreasing water weight (by increasing the urinary output). Regular consumption of detox teas might offer positive results in terms of weight loss. However, it does not result in fat loss. You will need to make lifestyle changes, follow good food habits, and exercise, along with drinking detox teas, to lose fat.
