1. Improve constipation and diarrhea
Probiotics help regulate the balance of the intestinal microbiota and can relieve both constipation and diarrhea. They enter the gut as live microorganisms and, through growth and metabolic activity, promote a healthy microbial environment. This helps suppress the production of putrefactive substances in the intestine and supports normal intestinal function.
2. Relieve lactose intolerance and promote nutrient absorption
Probiotics can break down lactose into lactic acid, thereby reducing symptoms of lactose intolerance and improving the digestion and absorption of nutrients in the gut. Bifidobacteria and Lactobacilli not only produce various vitamins, such as niacin and folic acid, but also help protect vitamin supply by inhibiting the breakdown of certain vitamins. In addition, Bifidobacteria can reduce blood ammonia levels and help improve liver function.
3. Prevent vaginal infections
Probiotics are not a single bacterium but a group of beneficial microorganisms. Some strains can acidify the urogenital tract by lowering the pH level, which inhibits the growth of harmful bacteria. By competing with pathogens for space and nutrients, probiotics help suppress their growth and reproduction, thereby promoting overall health.
4. Produce antagonistic metabolites and enhance immunity
Probiotics can produce organic acids, free fatty acids, hydrogen peroxide, and bacteriocins, which inhibit the growth of harmful microorganisms. They can also colonize the intestinal mucosa, skin, and other surfaces or intercellular spaces to form biological barriers. These barriers prevent the colonization of pathogenic microbes and help strengthen the body's immune system.
5. Alleviate allergic reactions
In people with allergic tendencies, exposure to allergens or biological stimuli can activate the immune system, leading to the production of immunoglobulins and the release of histamine, which causes allergic symptoms. Probiotic therapy is currently a widely used adjunct approach for allergy management. By regulating immunoglobulin levels, probiotics can help modulate immune responses and relieve allergic symptoms.
6. Support blood pressure control
Certain substances produced by lactic acid bacteria have blood pressure–lowering effects. Some probiotics can specifically break down proteins to produce bioactive peptides that inhibit enzymes associated with increased blood pressure. Long-term consumption of yogurt containing these active peptides may help prevent and manage hypertension.
As people age, the number of beneficial bacteria in the gut tends to decrease. Therefore, probiotics are not only for children-middle-aged and older adults can also benefit from appropriate probiotic supplementation to help enhance immunity and overall health.
