Culturelle probiotics are useful. Medical research shows that probiotics have the function of blood scavenger, which can remove cholesterol from blood vessel wall and relieve arteriosclerosis, heart insufficiency and fatty liver.
However, medical research shows that long-term use of synthetic probiotic products will gradually make the intestinal function lose the ability to reproduce beneficial bacteria and become dependent on probiotics supplemented by the outside world, which is called "probiotic dependence" in medicine. I have to rely on oral probiotics to maintain my health all my life. In addition, many probiotic strains are drug-resistant, and excessive use of probiotics is likely to breed new "superbugs".
