This strain of bacteria helps you burn off fat by speeding up your metabolism. Studies have found this strain of bacteria is also very effective at supporting the digestive system as well. B. Longum is a special strain that has been discovered to be protective of the intestines’ walls against pathogenic bacteria.

Additionally, it aids in the degradation of carbohydrates and proteins. One study [8] that examined the benefits of B. Longum in humans, specifically the clinically studied BB356, concluded the following:

It is effective at alleviating symptoms associated with respiratory, infectious, and immunological diseases.

It has been shown that it can maintain a healthy gut microbiota, as well as improve the intestinal climate.It may help to fight immune deficiency.

Lactobacillus Rhamnosus is another strain of bacteria that helps speed up your metabolism. It acts as a natural energy booster and helps fight fatigue that is often associated with poor digestion and an imbalanced gut flora.

Naturally occurring in the human body, L. Rhamnosus may also be isolated from any dairy product. It was reported that this particular genus-species pairing had been studied extensively in both adults and children. For 24 weeks, one study [1] examined the effect of L. Rhamnosus on weight loss and maintenance in obese people. This is what it found:

• On average, women taking LPR lost more weight than women taking a placebo.
• Women undergoing LPR consumption experienced improvements in their body weight, leptin levels, and fat.
• The differences between men receiving LPR and those receiving placebo were minimal or nonexistent.

This strain of bacteria is known to reduce body fat by decreasing leptin levels. Leptin is a hormone that is released by fat tissue and controls appetite.

Studies have linked obesity to higher leptin levels so reducing leptin levels is essential in order to maintain a healthy weight. L. Acidophilus continues to be among the most well-known probiotic bacteria.

Surprisingly, it has traditionally been used as a milk ingredient to promote proper digestion. It was revealed during the writing of this piece that L. Acidophilus is the only strain with very comprehensive clinical evaluations.

After deeper evaluations, a study [4] that examined its beneficial role in patients with (IBS) was discovered. The findings indicate that supplementing with L. acidophilus helps alleviate abdominal discomfort or pain. Finally, the researchers concluded the strain has a positive impact on those with IBS.

Lactobacillus Casei makes it easier for your body to digest food and supports your entire digestive system. It also helps relieve many digestive issues commonly associated with poor gut flora, such as IBS, diarrhea, and constipation.

Contrasting the other probiotics described here, L. Casei has the broadest temperature range and pH. Additionally, it reportedly aids in the development of Lactobacillus Acidophilus presented next here.

As HealthLine says [2], this bacteria is also present in the genital and urinary tracts to a lesser degree. Concerning its advantages, the summarized literature indicates that it could be beneficial in avoiding diarrhea, constipation, inflammatory bowel disease, infections, and much more.

Regarding its impact on being overweight, one analysis cites the findings of a study [3] conducted on mice. The goal was to give mice fermented milk with Lactobacillus Casei. This had a beneficial impact on their obesity biomarkers and microbiota.

This strain of bacteria is said to help “clean out” the digestive system and eliminates the bad bacteria from the body. It may also support immunity and helps with nutrient absorption.

According to one study [5], L. Plantarum has been widely used in foods due to its antimicrobial, antifungal, antioxidant, and antimutagenic properties [9]. It has so far been used in medicine to treat Alzheimer's disease, Parkinson's disease, diabetes, obesity, stroke, asthma, urogenital problems, and liver diseases.

Additionally, clinical studies [6] have shown that it has a beneficial effect on IBS, diarrheal disorders, and is believed to have anti-obesity properties. Concerning weight control, a previous study noted that it was consistent when it comes to mice losing weight [7].

Finally, this bacteria strain is associated with improved immune system function and metabolic function.

It may also remove bad cholesterol from your body and helps support healthy metabolic function. B. Breve is a bacterium that is said to be present in intestines and human breast milk.

In terms of gains when it comes to its anti-obesity properties, it decreases triglyceride levels and increases the HDL cholesterol ones, says a study [9]. As encouraging as these findings are, they cannot be extended to obese individuals, as this necessitates further study.
