What is Meiztang?

Meizitang is a dietary supplement manufactured to facilitate weight loss. Meizitang is formulated to detoxify the body and help reduce fat absorption. It is manufactured from plant extracts which are believed to enhance faster fat loss, increase body metabolism and supply vital minerals to the body.

Meizitang is also designed to facilitate the elimination of free radicals in the body in addition to enhancing healthy aging and improving skin elasticity.

What is Meiztang?

The source of Meizitang seems to be shrouded in mystery. There are several websites that claim to offer the authentic product, with disclaimers warning against other companies that sell imitation products. While numerous websites sell Meizitang, none of these websites provide information about the actual manufacturer of Meizitang.

It is believed that a Chinese company, Top Life International Co., Ltd., is the company behind Meizitang, and the company’s website lists Meizitang in its line of products.

Details of the company found online reveal that Top Life International Co., Ltd. was founded in 2001 as a nutritional supplement company specializing in weight loss, hair care and reproductive health products. The company’s website states that the factory where Meizitang is manufactured is located in the Guangdong Province of China.

Top Life International Co., Ltd. claims that it uses natural plants to create a product that has weight loss and slimming properties. There are three versions of Meizitang that are available: Original Meizitang Soft Gel, Meizitang Strong Version, and Meizi Evolution Capsule.

When Did Meizitang Start?

There is limited information on the initial formulation of Meizitang, and it is not clear when it was launched to the market.

The websites that claim to offer genuine Meizitang do not provide information regarding its history. Even the Top Life International Co., Ltd. website contains no information on the history of the product.


Meizitang Claims

The company producing Meizitang claims that by taking this supplement, a person can lose ten or more pounds in a week. The company asserts that Meizitang inhibits the function of the lipase enzyme in the stomach and intestinal canal to restrict the absorption of the fat contained in food.

Meizitang also allegedly increases an individual’s metabolic rate which leads to a breakdown in body fat and supplements the body with amino acids and trace elements like copper, iron, phosphorus, calcium, potassium, zinc and selenium.

Additionally, Meizitang is alleged to activate body cells and eliminate toxic elements. There are no clinical studies to back up these claims, and Meizitang is not approved by the Food and Drug Administration.


Meizitang Ingredients

Meizitang consists of five key ingredients, all of which are rooted in traditional Asian medicine.

Cassia seed extract (10%)

Cassia seeds have been used to relieve constipation and improve eye health.

Meizitang Ingredients

Although cassia seeds have laxative properties and are frequently used for weight loss, there have been no clinical studies proving that the seeds are effective for weight loss. Cassia seed is also known as Chinese senna.

ZiSu extract (25%)

ZiSu has been used in traditional Asian medicine to treat headaches, nausea, and appetite loss.

However, no studies have linked ZiSu with weight loss. ZiSu is also known as perilla.

Medical Amylum (35%)

Medical amylum is a complex carbohydrate found in foods like wheat and corn. Medical amylum is believed to suppress appetite as well as inhibit the conversion of non-fat foods to fat inside the body. However, there are no studies that prove that medical amylum is effective for weight loss.

Fuling Extract (17%)

Fuling is used in traditional Asian medicine as a tonic for the aged and those recovering from illness. There is no evidence linking fuling extract to weight loss.

Meizitang also contains smaller amounts of:

  • Lotus – traditionally used to treat pile and diarrhea.
  • Job’s tears – used in Asian medicine to treat obesity.
  • Tarragon – traditionally used has as a diuretic to enhance the production of urine as well as aid digestion.
  • Psyllium – used to treat diarrhea and constipation.

However, this long line of ingredients does not provide substantial evidence that back the claims of Meizitang.

In 2020, Meizitang upgraded their ingredients. Now, the supplement contains:

  • XianXian Cao
  • Jobstears
  • Artemisia Dracunculus
  • Psyllium Husk
  • Bamboo Shoot
  • Lotus Leaf
Benefits & Results

Meizitang Benefits And Results

The botanicals in Meizitang are believed to possess medicinal benefits that have been harnessed in traditional Asian medicine to:

  • Relieve constipation
  • Improve eye health
  • Relieve symptoms of headaches
  • Calm nausea
  • Promote appetite control

While the ingredients found in Meizitang are used to treat the various ailments listed above, there have been no clinical studies conducted that substantiate the claims of Meizitang to facilitate rapid weight loss.


The FDA On Meizitang Citrus

In 2013, the Food and Drug Administration revealed the results of laboratory analysis on Meizitang Citrus, a Meizitang product alleging weight loss. The results showed that Meizitang Citrus contained sibutramine, a controlled substance that was removed from the market in 2010.

The FDA warned that customers should stop taking Meizitang Citrus immediately and dispose of any remaining pills.

The FDA On Meizitang Citrus

In 2014, after conducting laboratory testing on Meizitang Strong Version Botanical Slimming capsules (another Meizitang product alleging weight loss), Australia’s Therapeutic Goods Administration reported that the pills contained diclofenac, a non-steroidal anti-inflammatory drug, even though the product packaging stated that the pills contained only natural extracts.

The TGA also discovered dipyrone, which had been linked with agranulocytosis – a fatal health condition, in the pills. Accordingly, the TGA warned that Meizitang Strong Version Botanical Slimming gel capsules posed serious health risks.

Under Australian law, supplements like Meizitang Strong Version Botanical Slimming gel capsules are required to be assessed by the Therapeutic Goods Administration for quality, safety, and efficacy.

Because the company failed to submit its product to the TGA prior to selling it, the sale of Meizitang Strong Version Botanical Slimming gel capsules was illegal in Australia (the Therapeutic Goods Administration findings show that Australians may have bought Meizitang Strong Version Botanical Slimming gel capsules online).


Meizitang Price

The price of Meizitang varies according to the type and quantity purchased and can range from $90 to $850.

The correct dosage of Meizitang is one capsule before or after breakfast.

Does it Work

Does Meizitang Work?

The claims made by the makers of Meizitang are substantial. While there are many ingredients contained in its formula, only one has laxative properties (and therefore thought to aid in weight loss), and it only accounts for only ten percent of the Meizitang formula.

It is unclear why the manufacturers of Meizitang use ingredients that have no links to weight loss in far greater proportion than the only ingredient that is thought to have some link with weight loss.

The one other ingredient in its formula that might aid weight loss is medical amylum which is alleged to suppress appetite.

The remaining ingredients in the formula do not contain properties that facilitate weight loss. Accordingly, Meizitang’s claims to aid weight loss are built on the inclusion of the two ingredients that are linked to suppressing hunger and relieving constipation.

It is difficult to assess the efficacy of Meizitang because the ingredients used in its formulation have not been studied in detail.

In addition, the lack of clinical studies on current Meizitang products on the market coupled with the hiccups Meizitang products have encountered with the FDA and TGA combine to make it challenging to determine what effect Meizitang has on weight loss.

Details On Meizitang And Weight Loss

Meizitang’s weight loss claims seem to be built on the properties of its ingredients that suppress appetite and act as a laxative. Cassia seeds have laxative properties, which may support weight loss, although there is little scientific evidence to support this claim. ZiSu extract, oriental water extract, and fuling extract have no known association with weight loss.

Available data on the plant extracts used in Meizitang does not provide substantial evidence linking them with weight loss.

Details On Meizitang And Weight Loss

There is also little proof that Job’s tears may aid weight loss. Lotus leaf has diuretic properties, which might aid weight loss, but like all diuretics, only bodily fluid is lost versus actual weight.

As stated above, there is scant information on the ingredients listed in the formulation of Meizitang and even less proof linking it with weight loss. The company behind Meizitang does not provide any scientific evidence to substantiate the efficacy of its formula.

Side Effects

Meizitang Side Effects

The laxative effects of Cassia seeds, a key ingredient in Meizitang, may cause bowel problems due to its laxative properties. It may even lead to a dependence on laxatives. Cassia can also cause weakness of muscles, and loss of electrolytes.

Medical amylum is extracted from foods like wheat and corn which presents a possibility of side effects. Medical amylum may cause gastrointestinal issues, stomach problems, and even diarrhea.

The discovery of diclofenac in Meizitang Strong Version Botanical by the Australian Therapeutic Goods Administration and the discovery of sibutramine in Meizitang Citrus by the U.S. Food and Drug Administration demonstrate that possible side effects of taking Meizitang can be fatal.

Because of the potentially serious outcomes, authorities have raised red flags on the consumption of Meizitang in those two countries.

Bottom Line

The Bottom Line on Meizitang

Now the moment you’ve been waiting for: our bottom line on Meizitang. Well, we like that the diet pills contain some natural herbs and that this supplement is easy to find online. But we have some reservations because it’s not supported by any actual clinical research. Also, we’re concerned about the questionable ingredient, as well as the side effects it can lead to.

If you’d like to drop more weight, then we suggest you go with a weight-loss app that provides you with all the resources you need to lose weight and keep it off.

Among the best products we’ve seen this year is one called Noom. This app is different from others because it comes with REAL human coaching, personalized meal plans, dedicated nutritionist support and expert articles and resources. The program is clinically proven – which is exactly what you need.

The makers of Noom are so sure about their product they’re offering a 14-day trial to Dietspotlight readers.

  • Authentic product availability
    jena (Verified Purchase)

    I used these pills before and they worked so well. They really curbed my appetite to where I got full so quick and I ate what I want BUT there are so many fake pills being sold on the internet. I have ordered about 4 differnt packs from different companies and they all are slihtly different in color. pleas just beware of all these fake pills. There is a paper inside the pack that warns people about the fake pills going around.Sadly, it only has a picture of the first fake pills that were being produced cause now there are MANY different fake pills that are being made and they are even putting the paper with the warning inside the package also.If u order some, make sure the pill should be between hard and soft,they should be VERY shiny and the liquid in there should be white. The paper that comes inside each pack should say that u should not get diarrea but one of the fake people who are making this paper too doesnt put anything about diarreea cause there bad pills do get u sick from ur stomach and they dont want u to know this ( some of the fake pills do say no diarrea on the paper inside the pack)Also “MZT” should be on the pill but even the fake pills have this engraved on them too. I cant get anymore pills from the lady I first bought them from cause it was in a flee market that I bought them from and I moved from that town. this is why I turned to the internet to order them but keep getting different pills. TO ME, the number one thing that will ring a bell that u have the real pills is ur mouth should get REAL DRY and YOU WILL NOT FEEL HUNGRY PERIOD.I havent came across those pills any where off the internet so far, if anyone can help me to find out the phone number to the actual manafacturer of this pill,I would appreciate it. THE PILL DOES WORK, ITS JUST FINDING THE REAL ONES IS WHATS HARD. I beleieve the name of the company that originated these pills is GMP FACTORY, but I am not sure.
