Iaso Teas, both Original and Instant, are claimed to help with weight loss and detoxification. But the lack of transparency about ingredients and the high price suggests you might want to look elsewhere for a detox tea.

Iaso Tea Review: Are Its Claims True? A Dietitian Explains


  • Easy to consume in a tea or powdered form
  • Tea is unlikely to have significant side effects


  • No information about dosages in product
  • No third-party testing
  • High cost for herbal tea
  • Original and Instant do not contain the same ingredients

What Is Iaso Tea?

Iaso Tea Original and Iaso Instant Tea are cleansing teas designed to help you detox, control appetite, and support “productive” trips to the bathroom (that is a direct quote from their website).

Although they are both called Iaso Tea, the ingredients in Original and Instant are not the same; I would expect them to be more similar.

There is also surprisingly little information about the amount of the ingredients and their benefits on the website.

Total Life Changes, the company that makes Iaso tea, has a downloadable guide to go along with their product.

Oddly, this guide focuses on the benefits of the amino acids in the tea. I don’t see how the product can contain a significant amount of any of the amino acids discussed in the brochure, as it has less than 1 gram of protein per serving.

Evaluation of Ingredients

Since the Original and Instant versions of Iaso are different, their ingredients are reviewed separately.

Note that it is difficult to evaluate the ingredients in this product based on the current research as the manufacturer does not list dosages.

Iaso Tea Original

The Original detox tea is a blend of different herbs that have mostly laxative and anti-inflammatory properties. These herbs include:


Myrrh is a type of resin that has been used for centuries for its medicinal properties. It was commonly used to treat bacterial infections and inflammation. It is a digestive aid and is primarily used as a laxative.

Blessed or Holy Thistle

Blessed thistle is an ancient plant that has been used throughout the ages to treat many different illnesses. It is commonly used to stimulate appetite and improve indigestion. It also has diuretic properties.

Papaya Leaf

Papaya contains an enzyme called papain that may help improve digestion. It may also help regulate blood sugar.

Persimmon Leaf

Persimmon leaves have been used for many centuries in Chinese medicine. More recently, research has found that they may have many beneficial properties for health, helping reduce inflammation, improve blood sugar, and fight bacterial infections.


Chamomile is an herb rich in flavonoids commonly used for its medicinal and relaxation properties. It may help improve sleep and have anti-inflammatory effects.

Malva Leaves/ Marshmallow

Malva and marshmallow are two herbs from the same plant family. Malva is commonly used for stomach problems and to reduce inflammation. Marshmallow is used for reducing irritation of the stomach.


Ginger is a root that can help soothe indigestion and helps reduce nausea.

Iaso Instant Tea

Iaso Instant contains only 4 ingredients: chamomile, papaya, soluble fiber, and senna. It does not contain the other ingredients that are found in the Original version.

Soluble Fiber

Soluble fiber is beneficial for digestion, increasing nutrient absorption, and lowering cholesterol.


Senna extract is a common laxative found in many products to relieve constipation. Since there is no dosage information provided with this product, it is impossible to know if the dosage is meant to provide mild relief or if it will have you immediately running to the bathroom.

Verdict on Claimed Benefits

Below is our summary of the available evidence for the claimed benefits of Iaso Tea based on the available research:

  • Promotes digestive wellnessModerate Evidence
  • Supports the circulatory systemModerate Evidence
  • Encourages healthy intestinesModerate Evidence
  • Healthy weight management assistanceNo Evidence

Side Effects, Safety, and Dosage

To make Iaso Original, two tea bags are added to a quart of boiling water, then steeped for 4–8 hours. The tea is consumed twice a day before meals and once before bedtime.

It is odd that it takes 4 to 8 hours to steep. This seems like a very long time; I am not sure what the benefit is here.

The Instant version is obviously instant. You just mix the powder into water and drink.

Overall, due to the company’s lack of information and dosages, it is difficult to determine if this product has any specific side effects.

Most of the herbs in Iaso Tea are commonly found in herbal tea blends, so with a few exceptions, safety concerns aren’t significant.

My main hesitation is the amount of senna in the Instant product. While senna is considered safe for occasional use, it can cause digestive problems and diarrhea. 

Myrrh and blessed thistle have been used to terminate pregnancies; therefore, this tea should not be consumed by pregnant women.

It is unclear if the fiber used in Iaso Tea is made from wheat dextrin. It should be avoided by those with a sensitivity to gluten.

It is best to speak to your doctor before trying this detox tea.


Iaso Tea Original is $49.95 for 5 tea bags on the Total Life Changes website. It can also be found on Amazon, where a 4 pack of tea bags is $49.95. One tea bag is around $12.

For the Instant version, on the Total Life Changes website, 50 sachets are $59.95. On Amazon, 25 sachets are sold for $44.95.

Paying $12 for one tea bag seems very excessive. Most boxes of “detox” tea you can find on Amazon run between $5–$15 for 15–25 tea bags.

How It Compares

There are dozens of detox teas with different herbal blends on the market. Many of these contain mild laxatives and herbs that may also help support liver function.

Other than going to the bathroom more frequently, I wouldn’t expect much from any of these blends, including Iaso Tea.

I would recommend avoiding detox teas, as they likely don't do much for you and may just give you bad diarrhea. 

If you struggle with constipation or irregularity, some of these products may help.

The Bottom Line

Iaso Teas are an expensive version of herbal tea with some natural laxatives added.

As a dietitian, I don’t think drinking this tea will do much for your digestion, weight, or pocketbook.

A Word from Our RD

If you are truly interested in detoxifying, your body is already equipped with everything it needs to do it naturally.

The key is to stop putting toxins in, such as processed foods, alcohol, sugar and smoking, and giving your digestive system and liver the ingredients needed to naturally detoxify, like water, fiber, and a healthy diet.
