What is Lactobacillus casei
Lactobacillus casei is a probiotic bacterium from the genus Lactobacillus known for its health benefits and wide use in fermented dairy products such as yogurt and kefir. This bacterium naturally colonizes the human gastrointestinal tract and is often used in probiotic dietary supplements.
Health benefits — Lactobacillus casei
- Support for digestive health: Lactobacillus casei helps maintain a healthy gut microflora, which is essential for proper digestion and the absorption of nutrients. This bacterium can reduce the symptoms of gastrointestinal disorders such as irritable bowel syndrome (IBS) and diarrhea, including antibiotic-induced diarrhea.
- Immunomodulation: This strain can boost the immune response by increasing antibody production and stimulating the activity of natural killer cells (NK cells). It can also help regulate inflammatory cytokines, reducing inflammation and increasing resistance to infections.
- Reducing inflammation: Studies have shown that this bacterium can have anti-inflammatory effects, which can be beneficial for conditions such as Crohn’s disease and ulcerative colitis. This bacterium can reduce the levels of proinflammatory cytokines and increase the levels of anti-inflammatory cytokines.
- Support for mental health: This probiotic can have a positive effect on mental health through the gut–brain axis. Studies have shown that it can reduce symptoms of anxiety and depression, improve mood and reduce stress.
- Protecting oral health: This bacterium can help maintain oral health by reducing the growth of pathogenic bacteria that cause gum disease and dental plaque. It helps reduce bad breath and the risk of periodontal disease.
- Lowering cholesterol: This strain can help reduce total cholesterol levels, including “bad” (LDL) cholesterol, while raising the level of “good” (HDL) cholesterol. These effects are especially beneficial for people who have a high risk of cardiovascular disease.
- Support for skin health: Studies have shown that this bacterium can reduce the symptoms of skin conditions such as atopic dermatitis and acne. This bacterium can reduce skin inflammation and improve the barrier function of the skin.
Potential side effects
This strain is safe to use, but some people may experience mild digestive discomfort such as bloating or gas. These side effects are usually temporary and subside after a few days of regular probiotic use.
How to use L. casei
L. casei is taken through probiotic supplements, but also through fermented dairy products such as yogurt and kefir. Regular, daily use with a meal is recommended, and its effect is complemented by a diet rich in prebiotic fibers. Before introducing a new probiotic, especially with chronic complaints, consult a doctor or pharmacist.
