You may have heard about the product in popular culture and its magnificent Iaso Tea properties to detox and cleanse your system, helping you drop some weight. 

But how effective is it in reality? Does it work? How well do the ingredients work? Is instant tea bad for you?

This Iaso Tea review will place the company’s claims under an objective, critical eye. 

Total Life Changes LLC (TLC), a company and a community of nutrition experts dedicated to creating health and wellness supplements and weight loss products, produces Iaso Tea.

What is Iaso Tea? The original formulation of this Iaso detox tea contained eight natural ingredients (not 9, as it would appear on the list above). Holy Thistle and Blessed Thistle refer to the same plant called Cnicus benedictus, suggesting that either the manufacturers or website developer incorrectly believed them to be different ingredients.

As of 2022, the company reduced its formulation for the original Iaso Tea to four ingredients: Cassia Angustifolia Extract (Senna), Papaya Leaves, Chamomile Leaves, and Persimmon Leaves.

TLC created it to help your body:

  • Remove toxins
  • Absorb nutrients
  • Rid harmful digestive junk 
  • Support the circulatory system
  • Lose weight

Some of the ingredients found in this tea aid with detoxification and better digestion, provide more physical energy, and might even help your skin.


According to the marketing pitch, people who get positive results may start to see pounds drop in as little as five days. However, detox products have the characteristics of being a bit ambiguous in their invested claims. Generally, the ingredients in the Iaso Tea product are natural laxatives. Because it does not include dosing information, it is difficult for dieticians to know if this product is safe or not for individuals.

In 1994, Jack Fallong had a vision of changing the world, and after putting all the pieces together, he started TLC in 1999. Since then, he has built a strong company and community around wellness and healthy life. TLC World Headquarters is located in Fair Haven, Michigan.

Review of the Science Behind Iaso Tea

The company dubs its Iaso Tea a cleansing drink due to its blend of well-known ingredients. Because all these ingredients are natural, the intestines’ cleansing is intended to be smooth and gentle. 

But let’s dissect this product into its components so that you can determine if it can really help detox your body and cleanse your intestines. 

Review of Iaso Tea Ingredients

The ingredients below reflect a previous formulation that TLC sold up until 2021. As of 2022, the company reduced the ingredients from eight to four. Two of the original ingredients (papaya and chamomile) were changed from extracts to leaves, one ingredient is the same (persimmon leaves), and one ingredient is new (senna). Most of the removed ingredients do not have strong scientific evidence to support their claims.

Holy Thistle

Also known as Blessed thistle (Cnicus benedictus), people have used this plant since ancient times to help digestion and prevent infection. They used it to treat patients with bubonic plague during the Middle Ages. 

Holy thistle is thought to help stimulate appetite and treat indigestion, diarrhea, and colds. People most commonly prepare it as tea or sell it as capsules or powder. The most common use of this herb is to promote the increase of breast milk in nursing mothers.  

No reliable research confirms the many benefits of holy thistle, so it is best to take it cautiously. This ingredient is no longer included in the current formulation.

Malva leaves/Marshmallow

Malva sylvestris is extensively used in traditional medicine to treat inflammation and injuries. These leaves are potent antioxidants and anti-inflammatory agents for the gastrointestinal and respiratory tracts.

This reddish-brown resin-looking substance also has anti-inflammatory properties, helping rid the digestive system of harmful bacteria. Through a steam distillation process, manufacturers obtain the myrrh essential oil.

Its antimicrobial properties make it suitable for treating oral infections and inflammation, but more studies are needed to prove this. People also use myrrh to heal wounds, fight pain and swelling, and treat stomach ulcers. 

Myrrh is probably an excellent antioxidant, but researchers have only performed these studies on animals. This ingredient is no longer included in the current formulation.

Ginger is another well-known flowering plant widely used to help soothe gastrointestinal irritation, relieve nausea, and stimulate bile and saliva production. This herb has many other potential uses – at least 115 compounds have proven its efficacy. 

Most of the work for ginger in the human body is therapeutic and powerful. There is evidence that ginger acts as an antioxidant, anti-nausea compound, anti-inflammatory agent, and even an anti-cancer agent. This ingredient is no longer included in the current formulation.

Review of Iaso Tea Ingredients (2022 formulation)

Persimmon leaves

In Korea, people use the leaves from the persimmon plant as tea, where some believe it has a positive effect against hypertension. Studies have reported that the bioactive compounds in persimmon leaves have significant dermatological and cosmetic benefits

The leaves contain vitamin C, fiber, amino acids, magnesium, and some tannins to aid digestion. They are part of the current formulation in 2022.

Papaya extract

The benefits of papaya are commonly known. Iaso Tea claims that the enzyme papain aids digestion and is high in fiber. Studies have found these properties of papaya nutrients to be correct. The current formulation contains papaya leaves.

Papaya contains fiber, folate, vitamins C & E, and beta-carotene. These components help free the colon cells from free radical damage. It has also been shown that regular consumption of this fruit reduces the risk of suffering colon cancer.

Due to its polysaccharide hydrocolloid content, it acts as a demulcent and soothes the mouth and pharyngeal mucosa against irritation and inflammation. As such, patients take this root extract orally. This ingredient is no longer included in the current formulation.


Chamomile is a well-known plant that has been around for a very long time. For centuries, people have used it to treat issues such as nausea, vomiting, heartburn, and upset stomach. 

There are many other ailments that, since ancient times, have been treated with chamomile. The dried flowers contain flavonoids and terpenoids, which give them medicinal properties. 

For TLC, Iaso Tea’s partial goal is to use its properties to aid sleep and digestion. The antioxidant apigenin helps sleep and reduces insomnia, as well as other characteristics that make this herbal tea an excellent companion for your digestive tract. The current formulation contains chamomile leaves.


A laxative that causes water loss and thus can lead to short-term weight loss. There is not a significant amount of scientific literature to support weight loss claims. Additionally, there is some concern for liver injury when used for long periods. This is a new ingredient in the current formula.

Review of Iaso Tea: The All-natural Cleansing Drink

How does it work?

According to the TLC website, drinking the tea removes toxins to clear a path inside your body. Once the patient has changed their heavy meal and started taking the Iaso Tea, the detoxification process occurs. 

For better Iaso Tea results, the company recommends combining it with your usual healthy diet and exercise routine.

You can order a five pack at $54.95. This contains five pouches where one pouch contains two bags of tea , equivalent to one gallon of weight-loss tea.

It should be noted that TLC offers more teas beyond the Original blend that contain additional ingredients. We will just mention them here.

Iaso Tea instant options
Iaso Tea instant options

No longer available: The “RASPBERRY – Instant Tea With Broad-Spectrum Hemp Extract – 25 Sachets” contains 100 mg of organic broad-spectrum hemp extract and over 12.5 mg of CBD per serving. 

The “Iaso® Tea Instant – 25 Sachets” is a proprietary blend containing four special extracts that help to better digestion. 

Buyers can also purchase an Iaso Tea Fruit Punch on the site and from third-party sellers. It is available in packages of 30 and 60 sachets.

These two products contain individual sachets that you can pour into a bottle of at least 17 oz. of hot or cold water. On the other hand, the “Iaso® Tea Original 5 Pack” we are reviewing here contains two tea bags you prepare to make 1 gallon of tea to store and serve in doses. 

Review of Iaso Tea Cost

Considering the total amount of tea you can prepare with the five-pack and the recommended dose, you pay $54.95 for about an 11-day supply. This represents an approximate investment of less than $5 per day. It does not sound too bad if you compare it to what you may spend on coffee or other drinks. This price is for individual customers to use the product.

It should be noted that you need to drink Iaso Tea long term before getting significant body weight loss and detoxification results.

The other option is to become a retailer of TLC products to make a profit through multi-level marketing. This is the TLC “Life Changer” program. It allows you to purchase the product in bulk as a distributor and get wholesale prices. As a member of this program you would purchase either the Business Starter Kit ($49.95) or International Life Changer Kit ($19.95).

Where to buy Iaso Tea: You can also purchase at retail prices online via Amazon, Walmart, eBay, and others, which may offer the products at a higher or lower price than the company website. At some places, and on the TLC website, you can purchase Iaso Tea kits.

Is Iaso Tea safe?

Teas are generally considered safe, but you must consider the ingredients before taking them as part of a regime. People under 18, pregnant, or nursing should consult with their physician before using this product. 

Also, if you have a health condition, it is best to consult first. The ingredients in Iaso Tea are natural, but you might have an allergic reaction to any of them, given unique allergies or predispositions. 

Review of Iaso Tea Privacy

TLC, the company that produces Iaso Tea, is seemingly committed to using high technology to protect information from unauthorized users. Also, your personal information will not be sold or given away to anyone. 

The company will never share your personal information without your consent, except for services that aid in processing such data. Of course, it will use your navigation behavior to send you offers and deals. However, you can opt out of these letters at any time you wish. 

Iaso Tea in the News

Recent news hasn’t been as positive. In 2022, the company has been at the center of several lawsuits.

Weeks after the pandemic surged, Total Life Changes (TLC) and two other supplements distributors received an FTC warning on social media posts “that unlawfully advertise that certain products treat or prevent Coronavirus Disease 2019.” 

In 2022, FOX13 discovered unhealthy amounts of THC in the Raspberry Lemonade Flavor Tea. This came right after a class action lawsuit where women blamed the Raspberry Lemonade Flavor Tea responsible for them failing a drug test and getting fired.

Other Iaso Tea Reviews

The TLC website has a space for reviews of its products. It seems like an open forum, but there are no reviews for some reason. Product testimonials on the company website tend to be very good.

Reviews from other sites are mixed, but, on average, Iaso Tea fares well among users’ opinions. It has a 4.1 star rating on Amazon. Generally, the positive reviews come from customers who say the product works and the negative ones are from those for whom it didn’t work and had side effects, such as increased need to use the bathroom.
