Lactobacillus salivarious for weight loss

Lactobacillus Salivarius Weight Loss Benefits: What Science Says?

Lactobacillus salivarius is a probiotic bacteria found naturally in the human digestive system. It is also commonly found in fermented foods like yogurt and kefir. This friendly bacterium has been studied for its potential health benefits, including aiding in weight loss. This article will explore the potential Lactobacillus salivarius weight loss benefits and how it may impact Metabolic syndrome.


Lactobacillus Salivarius Weight Loss Benefits: What Science Says?

Lactobacillus Salivarius Weight Loss Mechanism

The research regarding the impact of Lactobacillus on human weight is limited, primarily consisting of studies conducted on animals.

Parisa Shokryazdan and her colleagues conducted a study examining the effects of this probiotic on the productivity, intestinal health, and serum lipid levels of chickens.

For 42 days, the study revealed that administering Lactobacillus salivarius at concentrations of 0.5 or 1g per kg in the chickens' diet improved their body weight [1].

Another study titled "Effect of Lactobacillus salivarius Ls-33 on fecal microbiota in obese adolescents" supposed that the higher levels of Bacteroidetes, compared to fragilis, were associated with weight loss in adolescents and adults. The study didn't find any positive impact of Ls-33 on increasing the presence of Bacteroides while reducing Firmicutes [2].

Therefore, the research findings on the effectiveness of Lactobacillus salivarius remain contradictory, making it challenging to draw definitive conclusions.

Additionally, most studies that report increased body weight in animals focus on those raised for food production.

These studies aim to evaluate and find solutions to enhance body weight for industrial livestock. This effect can be attributed to the beneficial activities of Lactobacillus salivarius in the gut and digestive system.

As a result, it is challenging to establish a direct correlation between these findings and Lactobacillus salivarius weight loss benefits in humans.

However, it is undeniable that Lactobacillus salivarius has garnered recognition from numerous studies for its impact on the digestive system and its protective effects on the intestinal barrier.

Lactobacillus Salivarious does not influence weight

Lactobacillus Salivarius and Metabolic Syndrome

Besides its rumor about the potential impact on weight management, lactobacillus salivarius has been suggested to have effects on metabolic syndrome. However, due to ongoing controversies in research, precise conclusions on this matter still need to be made more explicit.

A study titled "Probiotics to Adolescents With Obesity Effects on Inflammation and Metabolic Syndrome" found no beneficial improvements for obese adolescents with whole-body metabolic syndrome.

On the other hand, another study proposes that Lactobacillus Salivarius could alter the microbial composition in the feces of obese adolescents unrelated to metabolic syndrome.

In contrast, Juan M. Rodríguez and colleagues observed that Lactobacillus Salivarius improved parameters related to metabolic syndrome, gout episodes, and blood markers associated with oxidative stress[3].

Finally, while it may not directly influence weight loss efficacy or metabolic syndrome, this probiotic strain's effects can improve digestion, metabolism, and overall health.

How To Use Lactobacillus Salivarius for Weight Loss And Overall Health?

Food That Contains Lactobacillus Salivarius

There are several ways to incorporate lactobacillus salivarius into your diet. One of the most effective methods is consuming probiotic-rich foods containing this bacteria. Some examples include yogurt, kefir, sauerkraut, kimchi, and tempeh. When purchasing these foods, check the label for lactobacillus salivarius.

Probiotic Supplements That Contain Lactobacillus Salivarius

Another way to consume Lactobacillus salivarius is by taking probiotic supplements. These supplements are available in various forms, such as capsules, powders, and gummies. It is essential to choose a high-quality supplement from a reputable brand to ensure the effectiveness of the probiotic.

Recommended Dosage

No specific recommended dosages for Lactobacillus salivarius have been officially established for weight loss. Nevertheless, numerous studies have been conducted using daily doses ranging from 1 to 10 billion CFU and consistently found no significant adverse effects.


While the research on Lactobacillus salivarius and its potential impact on weight loss is still ongoing, promising results suggest its role in improving metabolic health. Including this probiotic in your diet, whether through fermented foods or supplements, may benefit your overall well-being. However, as with any supplement or dietary change, it is essential to consult with a healthcare professional before making any significant changes to ensure safety and effectiveness for your specific needs.
