The difference between probiotic supplements and yogurt bacteria is mainly manifested in the strains used, processing technology, product form and other aspects. 1. Probiotics strains are mainly Bifidobacterium lactis, Lactobacillus acidophilus, Lactobacillus rhamnosus, etc., which can inhibit harmful bacteria and pathogenic bacteria by entering the human intestinal tract and parasitizing in the intestinal tract, and assist in improving the human immunity. The main strain of yogurt is lactobacillus, which can make the protein in milk or milk powder decompose into more easily absorbed nutrients. 2. Probiotics are made through constant temperature and humidity, hydrolysis process, fermentation process, cooling and extraction, etc., while yogurt is made by adding strains of bacteria to milk and milk powder at the right temperature. 3. Probiotic strains are put into dormant mode by freeze-drying, and wake up to take effect after being taken orally into the intestinal tract, while the strains in yogurt are drastically reduced in number due to the corrosive effect of gastric acid when entering the digestive tract. It should be noted that most probiotics are a kind of medicine or health care product, used when the organism is in a state of disease or sub-health, yogurt is a kind of food, as long as it is not allergic to it, the general population can be consumed.
