What is Lactobacillus salivarius?
Lactobacillus salivarius is a probiotic bacterium from the Lactobacillus genus. It is found in the mouth, gastrointestinal tract, and vagina. This bacterium is known for its probiotic properties and is used in many supplements and fermented foods.
Health Benefits
- Oral Health Improvement: Lactobacillus salivarius plays a key role in maintaining oral health. It produces bacteriocins, antimicrobial substances that help combat pathogens causing gum diseases and dental plaque. Studies show that it can reduce bad breath and the risk of periodontitis, as well as improve overall gum health.
- Digestive Health Support: This bacterium helps maintain a healthy gut microflora, reducing symptoms of gastrointestinal disorders such as irritable bowel syndrome (IBS) and inflammatory bowel disease (IBD). Lactobacillus salivarius produces lactic acid, which helps suppress the growth of harmful bacteria and supports the health of beneficial bacteria. It also aids in protein digestion and reduces inflammation caused by Helicobacter pylori.
- Cholesterol Reduction: Studies have shown that Lactobacillus salivarius can help reduce cholesterol levels. Subjects have recorded reductions in total cholesterol, including "bad" (LDL) cholesterol and triglycerides, while increasing "good" (HDL) cholesterol. This effect is particularly significant in individuals at high risk of cardiovascular diseases.
- Immune System Support: Lactobacillus salivarius can enhance the immune response of the body. It increases antibody production and helps regulate inflammatory cytokines, which can reduce inflammation and improve resistance to infections.
- Liver Protection: Research on models with non-alcoholic fatty liver disease (NAFLD) shows that Lactobacillus salivarius can reduce fat accumulation in the liver and lower serum triglyceride levels. This effect is partially mediated through the regulation of specific genes involved in lipid metabolism.
Potential Side Effects
Lactobacillus salivarius is generally safe for use, but like other probiotics, some people may experience mild digestive disturbances such as bloating or gas. These side effects are usually temporary and subside after a few days of regular probiotic use.
