ProbioSlim Review: Does it work?

Intro: What is it?

ProbioSlim is a weight loss pill featuring probiotic bacteria with green tea meant to help you lose weight and improve digestion, and without side effects. They also claim that the probiotics added restore the body’s pH; this is meant to potentially clear up skin.

The way this brand is meant to reduce weight is by providing green tea which is intended to get rid of fat easier. Also, the added caffeine is used to provide energy and reduced appetite. The company mentions a reduced-calorie diet is advised with ProbioSlim.  So what can this brand really do? Is it effective for weight loss and for proper digestion? This full review has all the information you need to know.

ProbioSlim Ingredients

The company fails to list the ingredients in a convenient location on their official website; you have to be in the stage of purchasing to see the supplement label. Each pill has a proprietary blend called the LS3664 Whole Health Superblend, totaling 544 mg of the following:

LactoSpore Bacillus Coagulans Super EGCG Green Tea Leaf Extract(50% EGCG) Green Tea Leaf Extract(50% caffeine) Kiwi Extract
Fig Extract Papaya Extract

Some ingredients to examine further:

LactoSpore: Patented bacteria made by the Sabinsa Corporation. It’s used to treat abdominal pain and IBS, or irritable bowel syndrome. There’s doubt this probiotic strain has any effect, according to Web MD it’s also known as bacillus coagulans:

has not been studied in people”

“no reliable research done”

“not enough information (if it’s) sic safe to use”

So it’s not known if this strain is effective for any of the claimed benefits.  Web MD also mentions that although this ingredient is all natural, this does not mean it’s safe.

The makers of LactoSpore also mention to get 100-200 million of the bacteria 3 times a day. The owners of ProbioSlim fail to list the total amount added, and their serving times are different at only twice a day.

EGCG: Extract taken from green tea which the company claims leads to fat loss. According to, this effect is only possible through the added caffeine found in green tea, which only works for short periods and in people who don’t take caffeine often.  EGCG has not been proven to be useful for weight loss on its own.

Caffeine: A stimulant that’s extracted from green tea leaf. Caffeine may be potentially dangerous, especially since the manufactures fail to list the total amount provided. When taking caffeine for weight loss, it’s suggested to only use it for short periods. Once the body builds a tolerance to caffeine it’s known to limit the overall positive effects.

Kiwi, Papaya, and Fig extract: All know as prebiotics due to either their fiber source or natural enzymes. The company does not list the nutritional fiber provided, so it’s unknown if there’s any effect from these additives. There’s also no specific mention as to what these ingredients offer individually.

Also added in unknown quantities are these 2 ingredients:

Chlorophyll Titanium Dioxide


Chlorophyll: Plant based pigment that gives plants a green color. According to Web MD:

“there’s not enough information (to know) sic if it might work”

It’s often touted as a superfood which has many health benefits, though no studies have been conducted to know for a fact whether or not it’s useful.

Titanium Dioxide: Often used as a food coloring. This ingredient has been described as being:

possible carcinogen to humans”

This is according to the International Agency for Research on Cancer.  Web MD also mentions that some may experience a severe allergic reaction.  This can lead to symptoms such as hives, difficulty breathing, swelling, and dizziness. It’s recommended to seek medical attention if any of these symptoms occur.

The Quality of ProbioSlim’s ingredients

There are not enough studies done on the main ingredients. Their proprietary blend fails to provide any nutritional value, and it relies heavily on ingredients you can get elsewhere for a less expensive price.

There’s also ingredients such as Chlorophyll and EGCG, which have not been tested enough to show whether or not they can produce safe and reliable effects.

The Price and Quality of ProbioSlim

Each $69.99 bottle has 60 capsules, and it’s recommended to get 2 pills a day. Therefore the daily price translates to:

$69.99/30= $2.33 for a full serving a day.

Several customers on multiple websites such as, Consumer, the Better Business Bureau, and more have complained about the company automatically billing each month.

There’s also concern over the lack of clinical studies. The probiotic strain has not been independently tested to show if it’s either safe or effective. As far as fat burning, many customers have complained they failed to see any change even with diet and exercise.

Due to the unknown amounts of caffeine, potentially harmful additives, and the lack of proven benefits, ProbioSlim fails to prove it’s useful.

The Fat Burning Claims

The company mentions that the added EGCG in the green tea is useful for fat oxidation and increased thermogenesis.

Another easy way to get the same intended effects of this brand is by simply drinking green tea. Not only is this cheaper, but at least you’ll know exactly how much caffeine is added.

The FDA has given out multiple warning letters against companies who claim EGCG is effective for weight loss.  The European Food Safety Authority which is Europe’s version of the FDA also mentioned that green tea is:

not sufficiently characterized in relation to the claimed effects”

These effects included thermogenesis and oxidized fat.

No positive human effects have been listed as possible according to US and European studies.

Another benefit intended to occur is through the addition of caffeine. According to the official website, this ingredient can suppress appetite and increase energy. These effects are possible depending on the amount of caffeine added.

Nowhere dos the company list the amounts of caffeine included.  Mayo Clinic mentions:

heavy caffeine use can cause unpleasant side effects”

They also add that the following people shouldn’t use it. Excluded are those that are:

“highly sensitive to its effects or who take certain medications.”

The possible side effects can include nausea, headaches, rapid heart rate, muscle tremors, anxiety, and insomnia.  It’s important to determine the amount of caffeine added since it’s the only potentially useful fat burner added. Still, in unknown quantities it may produce heavy side effects. Also, caffeine is only effective for short periods; the human body quickly adapts and makes it less useful.

Length of Use

It’s recommended to take this brand for:

at least three months to experience the full benefits.”

This isn’t a helpful amount of time, considering the company only offers a confusing 18 day free trial, which must be called off by customers. In this short time span it’s unknown if this brand will actually produce effects.

To people who still use it for the recommended time, they won’t be allowed a return on money if they fail to see results. Also, the money back guarantee is only for unopened bottles.  So in any case, you’re forced to spend at least $69.99 for a potentially useless product.

Business of ProbioSlim

The company is named ProbioSlim, LLC, not many details are provided by the company themselves. They can be reached below:

Phone Number: (877) 869-3308

Address: 24 School Ste 401

Boston, Massachusetts 02108

The company has totaled 61 different complaints against them on the Better Business Bureau website. Here are some common complaints:

  • Customers have complained about the company running a scam. Some have alleged they charge monthly with no way to reach customer service representatives. 3 customers mentioned they called the company and were immediately sent to voicemail with no one responding back after weeks.
  • The biggest complaint at 31 negative reviews is reports of the company auto-billing each month. The official website offers a free sample trial which customers allege it forced them to have to pay for ProbioSlim each month.

Customer Opinions

Customers did review the product itself on websites such as where there are 312 negative reviews:

“Did not lose one pound”

“saw no positive effects”

“Took it for a month and no results”

“I did not notice a change in my digestive system”

Several people complained about being included in an auto-ship program. There’s also the majority opinion that his brand has no effects at all. There were mixed reports about digestion, with some adding it may be due to a placebo effect.

Overall, the major complaint was that they took the brand and even included diet and exercise; they still failed to see any benefit.


Many issues sprang up with ProbioSlim:

  • There’s no proof this brand works: The company never mentions any clinical studies, nor do they provide any sort of proof. They also never cite exactly what makes up their blend of ingredients. The added caffeine and amounts of nutrients from the fruit is never listed. They do list a section for customer written reviews, but without names or pictures its unknown if these people actually exist. Without any reliable evidence you’re left to look at all the customer reviews. So far there are over 500 negative reports about the lack of effects.
  • Customers have complained about the companies practices: Several negative reviews are available online from angry customers. People mention that when requesting a free sample the company will enroll people into an automatic billing plan. There’s also been major concern over the lack of customer service representatives. Many have revealed they’ve tried calling and leaving voicemails but there’s never a call back. A few customers have said this company runs a scam. The manufacturers did respond back to certain customers on the Better Business Bureau, but there are still hundreds of unanswered requests from customers who wanted their money back.
  • The retune policy is only for unused bottles: The company has an 18 day trial they offer for people, if not satisfied you have to return only unused bottles after 30 days of having received this brand. However, a full bottle lasts 30 days, which is longer than the offered 18 day trial. It’s impossible to know if this brand is producing an effect before having to send it back. The manufactures also mention that it may take up to 3 months to experience an effect. It doesn’t make any sense that it can take up to 3 months for there to be change. This long amount of time will result in 3 full bottles wasted at a total of $209.97
  • There’s no nutritional value to the proprietary blend: The prebiotic formula is made up of Fig, Kiwi, and Papaya. These ingredients are said to promote a healthy digestive system. It’s never revealed if there’s any nutritional value to these ingredients. Enzymes in these ingredients are used to promote a healthy body, but it’s unknown if they’re preserved in this formula, or at what strength they’re available in. Prebiotics are fiber compounds used to feed bacteria. Without knowing how much fiber is provided, it’s unknown if there will be any change in the body at all.
  • Unknown levels of caffeine are added: The company mentions there’s caffeine included, but it’s unknown at what levels. Nowhere on their official website do they list the amount of caffeine present. They do mention that you have to reduce calories to lose weight while taking caffeine, but no mention of the strength is provided. It’s important to know the total amount of this stimulant, since high amounts can lead to unwanted side effects which some customers did report. Possible symptoms can include rapid heart rate, tremors, anxiety, and mood swings. Caffeine also builds up a tolerance which can make it non effective yet still potentially damaging.

Many customers have complained about the company’s policies and some add that the company automatically charges people each month. The company also includes ingredients in unknown amounts, which is important to know if you’re trying to stay within a safe and healthy range. Without knowing the full amount of caffeine, it’s unknown what kind of an effect ProbioSlim might have.
