The efficacy of probiotics is highly dependent on the specificity of the strain.
What we usually hear about "Bifidobacterium lactis", "Lactobacillus rhamnosus", etc. are "strains", which is a large name for related species. Under these strains, there are Different strains, and these are the ones we really want to use!
The state has approved 7 bacterial strains and 9 strains can be used in children’s food:
1. Lactobacillus acidophilus (NCFM)
2 , Bifidobacterium animalis (Bb-12)
3. Bifidobacterium lactis (HN019, Bi-07)
4. Lactobacillus rhamnosus (LGG, HN001)< /p>
5. Lactobacillus reuteri (DSM17938)
6. Lactobacillus fermentum (CECT5716)
7. Bifidobacterium breve (M-16V)< /p>
(The above seven species are strains, the strain number is in brackets, ***9 species)
So when buying probiotics, you must carefully look at its strain number. If there is no exact strain number, it is best not to buy it.
For example:
(Picture quoted from Ziyu Academy)
We can clearly see the strain name + strain number from the packaging, only Only by labeling the two at the same time can the product be "authenticated", indicating that this product is a member of the true probiotic family.
In addition, different strains have different effects. For example
The biggest role of Lactobacillus rhamnosus LGG is to attach to intestinal epithelial cells and become a biological barrier for the intestinal mucosa, which can alleviate diarrhea problems to a certain extent.
Bifidobacterium animalis (Bb-12) can secrete a variety of enzymes to promote the degradation and absorption of food. It has been clinically found that it can improve the utilization rate of dairy products in patients with "lactose intolerance". In addition, it can prevent allergic problems to a certain extent.
If the baby has diarrhea and the parents give the baby Bibacterium animalis (Bb-12), of course it will have no effect!
In short, only by using the right strain can symptoms be alleviated in a targeted manner.
