At present, the probiotic products on the market are mixed, the quality is uneven, the source of strains is unknown, and there is a lack of scientific research verification. Most of them think that lactic acid bacteria and bifidobacteria are synonymous with probiotics and have no awareness of strains. It is urgent to improve the relevant industry standards and national standards of probiotics and standardize the probiotic industry.

Related functions:
1, promoting the digestion and absorption of nutrients.
Probiotics can synthesize digestive enzymes. Together with digestive enzymes synthesized by animals, it participates in the digestion of nutrients in the intestine, stimulates animals to secrete digestive enzymes, reduces the depth of small intestinal crypt, increases the height of villi, increases the surface area of small intestine, and promotes the absorption of nutrients in the intestine.
2, improve the body's immunity
The structures of probiotics, such as peptidoglycan and lipoteichoic acid, can be used as antigens to directly activate immunity, or can stimulate the host immune system through autocrine immune activators, thus improving the immunity of animals, enhancing the activities of innate immune cells and natural killer cells, activating dendritic cells, stimulating the body to produce cytokines and stimulating B cells to secrete antibodies. Probiotics can stimulate the intestinal tract to produce secretory globulin A(SIgA) and protect health.
3. Maintain the structural balance of intestinal flora.
Intestine is not only a normal part of the body, but also participates in important physiological activities of the body. At the same time, there are complex intestinal flora in the intestine, which plays an important role in the growth, development and health of the host.
