Probiotic powder is generally recommended to be taken after meals. Normal human intestine is in a balanced state of flora, when infected or under the effect of some drug factors, it will lead to intestinal flora imbalance, causing some bacteria to shift, and patients will have some symptoms of digestive tract, such as bloating, abdominal pain, diarrhea, constipation and so on. Probiotic supplementation can maintain the balance of intestinal flora to a certain extent, inhibit harmful bacteria, and play a certain anti-inflammatory role. Probiotics are generally recommended to be taken after meals, because the acid-base value in the stomach is lower after meals, which is less damaging to probiotics and can make most of the bacteria survive and thus enter the intestinal tract to replenish beneficial bacteria. Also note that probiotics should be stored in the refrigerator insulation layer, and taken with warm water, the temperature should not exceed 40 ℃, so as not to kill the probiotics. Note that do not use with antibiotics, must be applied with antibiotics must be more than 2 hours between the time of taking.
