1, Lactobacillus rhamnosus: belonging to the genus Lactobacillus, it is one of the normal flora of human body, with high intestinal adhesion rate and strong colonization ability. It has important physiological and health care functions of effectively lowering cholesterol and promoting cell division, and can regulate intestinal flora, prevent diarrhea, eliminate toxins, prevent dental caries, improve immunity and resist cancer.
2. Bifidobacterium lactis: it is a representative of beneficial bacteria. Lactic acid and acetic acid are produced after intestinal fermentation, which can improve the utilization rate of calcium, phosphorus and iron and promote the absorption of iron and vitamin D. Galactose produced after fermentation is a component of cerebrosides in the cranial nerve system, which is closely related to the rapid growth of the brain after the baby is born. Bifidobacterium can produce vitamins B 1, B2, B6, B 12, alanine, valine, aspartic acid, threonine and other essential nutrients, which have important nutritional effects on human body.
3. Lactobacillus fermentum: Lactobacillus fermentum is one of the normal flora of human body, which can pass through the gastrointestinal tract of human body smoothly and is the main flora in the gastrointestinal tract. Besides acetic acid, lactic acid, succinic acid and putrescine, it can also metabolize bacteriocin, which can not only inhibit gram-positive bacteria, but also kill gram-negative bacteria such as Escherichia coli, Pseudomonas and Salmonella. It can also promote the development of the immune system.
4. Lactobacillus reuteri: a beneficial bacterium in human body, which has the functions of improving allergic constitution, preventing allergic recurrence and regulating intestinal function.
