There is no such thing as “taking probiotics several times a year”, and healthy people without gastrointestinal disorders generally do not need to take probiotics. Probiotics mainly include Bacillus licheniformis capsules, Bifidobacterium bifidum, etc., which can be used for the treatment of acute and chronic diarrhea, intestinal flora disorders, gastrointestinal disorders and other diseases; however, healthy people who do not meet the above indications do not need to use probiotics for treatment, so there is no such thing as “how many times a year do you take probiotics”. Probiotics can only be taken when there are indications for probiotics, and the number of times per year that probiotics can be used for this group of people is not fixed, and the treatment needs to be in accordance with the doctor’s instructions. It should be noted that the normal population of long-term use of probiotic treatment, may interfere with the normal flora structure in the body, is not conducive to intestinal digestion, absorption, and may even induce intestinal diseases. People who need to maintain intestinal health can do so by drinking yogurt or eating foods rich in dietary fiber, such as various vegetables and fruits. Patients who need to use probiotics for treatment should use medication under the guidance of a doctor and should not blindly use medication on their own for treatment.
