What Are the Functions of Probiotics?

Probiotics can relieve the symptoms of lactose intolerance and promote the absorption of nutrients in the body. Probiotics function to aid in the digestion of nutrients in the gut. It breaks down lactose into lactic acid and relieves lactose intolerance. Bifidobacterium and Lactobacillus can not only produce various vitamins such as vitamin B1, B2, B6, B12, niacin and folic acid for the body's needs, but also ensure the supply of vitamins by inhibiting certain vitamin-decomposing bacteria. In addition, bifidobacteria can also reduce blood ammonia and improve liver function. So in addition to this role, what are the probiotics functions?


1. Probiotics function: probiotics have the effect of regulating the intestines, adjust the micro-ecological disorders, and prevent diarrhea


Probiotics enter the human intestinal tract alive, promote the normalization of intestinal bacterial flora through their growth and various metabolic effects, inhibit the production of intestinal spoilage substances, and maintain normal intestinal function. One of the functions of probiotics is to treat and prevent viral and bacterial acute enteritis, dysentery, and constipation. Probiotics are closely related to many chronic gastritis, peptic ulcer and other digestive tract diseases. Some probiotics can resist gastric acid, adhere to the surface of gastric wall epithelial cells, inhibit the growth of Helicobacter pylori through their metabolic activities, and prevent the occurrence of gastric ulcers.


2. Probiotic function: Probiotics can metabolize products to produce biological antagonism and enhance human immunity


One of the functions of probiotics is to produce organic acids, free fatty acids, hydrogen peroxide, and bacteriocin to inhibit the growth of other harmful bacteria; through "biological oxygen capture", aerobic pathogens are greatly reduced, and probiotics can colonize in Biological barriers are formed on surfaces such as mucous membranes and skin or between cells, which can prevent the colonization of pathogenic microorganisms and play a role of occupying space, competing for nutrients, mutualism or antagonism. Probiotics can also stimulate the body's non-specific immune function, increase the activity of natural killer (NK) cells, enhance the secretion of intestinal immunoglobulin IgA, and improve the intestinal barrier function.


3. Probiotics function: the effect of probiotics on hypertension


Certain substances produced by lactic acid bacteria such as gamma-aminobutyric acid (GABA) have the effect of lowering blood pressure. Another part of the function of probiotics is to specifically decompose milk protein (casein) to produce polypeptides (such as VPP and LPP) that have the activity of inhibiting the enzyme (angiotensin-converting enzyme, ACE) that causes blood pressure to rise. Long-term drinking of yogurt containing this active polypeptide has the effect of preventing high blood pressure.
