Probiotics are best eaten at the following two times: 1. When you just wake up: Because children do not eat food or have strenuous activities after waking up, the concentration of gastric acid in children’s gastric juice is relatively low, which can minimize the destruction of probiotics on gastric acid and help probiotics to play a greater efficacy. The probiotics can be given to the child after the activity, especially after eating, the stomach acid will be secreted more, then give the child to eat probiotics, often resulting in a decline in the effectiveness of probiotics. 2, before going to bed at night: children at night before going to sleep, stomach acid secretion is relatively inactive, at this time to give the child probiotics, can also maximize the effectiveness of probiotics. Most of the probiotics can adjust the child’s nausea, vomiting, anorexia, abdominal pain, thin stools or dry stools and a series of symptoms caused by the disorder of intestinal flora. In addition, probiotics can reduce the child’s allergic status, so as to relieve the symptoms of eczema, bronchial asthma and other allergic diseases. In summary, it can be seen that when children take probiotics, it is most appropriate to take it in the morning when they first wake up on an empty stomach, or at night before they go to sleep.
