Lactococcus lactis, also known as Lactobacillus lactis, is a probiotic bacterium commonly used in the fermentation of dairy products, including milk, cheese, and yogurt. This bacterium is well-known for its health benefits and extensive use in the food industry.
Health Benefits
Digestive Health Support: Lactococcus lactis helps maintain a healthy gut microbiota, reducing symptoms of gastrointestinal disorders such as irritable bowel syndrome (IBS) and diarrhea. This bacterium produces lactic acid, which lowers the pH in the intestines, creating unfavorable conditions for pathogenic bacteria.
Immunomodulation: Lactococcus lactis can enhance the immune response by increasing antibody production and stimulating the activity of natural killer (NK) cells. It also helps regulate inflammatory cytokines, reducing inflammation and increasing resistance to infections.
Reduction of Allergic Reactions: Studies have shown that Lactococcus lactis can reduce allergy symptoms, including atopic dermatitis. This probiotic helps modulate the immune response to allergens, reducing inflammation and improving symptoms.
Skin Health Support: Lactococcus lactis can have a positive effect on skin health. This bacterium can reduce skin inflammation and improve its barrier function, which is beneficial for conditions such as eczema and acne.
Cholesterol Reduction: Lactococcus lactis can help lower total cholesterol levels, including "bad" (LDL) cholesterol and triglycerides, while increasing "good" (HDL) cholesterol levels. These effects are particularly beneficial for individuals at risk of cardiovascular diseases.
Oral Health Support: 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 periodontitis.
Potential Side Effects
Lactococcus lactis is generally safe for use, but like other probiotics, some people may experience mild digestive issues such as bloating or gas. These side effects are usually temporary and subside after a few days of regular probiotic use.
