ProbioSlim Review

What Are The ProbioSlim Ingredients?

ProbioSlim is composed of a patented probiotic strain called LactoSpore along with what the brand calls “advanced weight management ingredients”. Let’s get into the details. 


LactoSpore is a patented form of the probiotic strain Bacillus coagulans MTCC 5856.

This strain was examined for its potential role in weight loss in a clinical trial featured in the Journal of Chiropractic Medicine 

Over the 3-week trial period, the participants lost 8.6 pounds. Initially, these results seem impressive.

However, it’s important to note that the trial participants were adhering to a substantially reduced-calorie diet, a factor that alone could lead to weight loss. 

In our opinion, this trial is inadequately designed. To establish whether LactoSpore induces weight loss, a more effective approach would be a placebo-controlled trial. 

While the ability of this probiotic strain to promote weight loss is unclear, there is research that demonstrates the gut health benefits of this strain. 

For instance, a 2023 publication in the journal Medicine states, “B coagulans strains can also produce short-chain fatty acids, improve the intestinal environment, promote healthy bowel movement, and enhance the health of gut cells.”

The journal continues to report on the benefits of this strain by saying, “In this study, B coagulans MTCC5856 showed promising results by dramatically lowering gas, bloating, and flatus related symptoms in patients with functional bloating who did not have other serious gastrointestinal diseases.”

Thus, if you have gas, bloating, or just want to promote healthy bowel movements, ProbioSlim may be a good option for you. 

Green Tea

Green tea extract is included in the ProbioSlim formula because it contains catechins and caffeine, two compounds that are each believed to have a role in increasing energy metabolism, which may lead to weight loss.

While some studies show that green tea can help with weight loss, the amount of weight loss in the studies is typically small. 

For example, a publication in the Cochrane Database of Systematic Reviews states, “Green tea preparations appear to induce a small, statistically non-significant weight loss in overweight or obese adults. Because the amount of weight loss is small, it is not likely to be clinically important. Green tea had no significant effect on the maintenance of weight loss.”


The recommended dose of ProbioSlim contains about as much caffeine as one and a half cups of coffee.

As you probably know, caffeine is a stimulant, and as such, caffeine temporarily stimulates the rate at which your body burns calories. Thus, caffeine may contribute to weight loss over time.

Moreover, caffeine has been shown to increase the oxidation of fats. This means that it helps the body use stored fat as a source of energy, potentially aiding in fat loss.

Lastly, caffeine may have a mild appetite-suppressing effect. Consuming caffeine can lead to a short-term reduction in appetite, which can contribute to lower calorie intake.

Ultimately, the inclusion of caffeine in ProbioSlim should help to give you more energy while also potentially helping you to lose weight. 

Prebiotic Fruit Extract

ProbioSlim contains kiwi, fig, and papaya extracts that serve as prebiotics.Prebiotics are non-digestible fibers that serve as nourishment for probiotics (in this product, the LactoSpore probiotics) helping them flourish and exert their positive effects.

Does ProbioSlim Help You Lose Weight?

The ingredients in ProbioSlim that may help promote weight loss include probiotics, green tea leaf complex, and caffeine. 

While these ingredients have research to suggest their potential to support weight loss, we wanted to point out that even the brand recommends that this supplement should be combined with a reduced-calorie diet in order to lose weight. 

What Are The ProbioSlim Benefits?

After reviewing the ingredients in this supplement, we have determined that the benefits of ProbioSlim include improved gut health, healthier digestion, and weight loss. 

Improved Gut Health

As a probiotic, LactoSpore promotes the growth of beneficial flora, helping to reduce the proliferation of non-beneficial bacteria and, ultimately, supporting a balanced gut microbiome. It has also been shown to enhance the health of gut cells. 

Healthier Digestion

LactoSpore has been shown in studies to help ease symptoms associated with occasional diarrhea, constipation, gas, and bloating. 

Weight Loss

As mentioned above, the probiotics, green tea leaf complex, and caffeine in this formula can help to promote weight loss as part of a reduced-calorie diet. 

How to Take ProbioSlim?

Take 1 capsule with breakfast and 1 capsule daily with lunch.
