It is best to take probiotics 20 minutes after eating because the concentration of stomach acid is decreasing in this period of time, which is very good for the live bacteria to reach the human stomach smoothly, so that the probiotics can play the role of the human body to the maximum. When the food is eaten into the stomach, it will consume most of the stomach acid, which is very good for the probiotics to flow into the small intestine better, otherwise it is easy even if some of them can flow into the small intestine, but they will be damaged, so that the effectiveness of probiotics will be greatly reduced, and the best effect will not be achieved. In addition, we need to pay attention to the probiotics should not be boiling water at the same time, or high temperature will kill many probiotics, resulting in the loss of efficacy, so in twenty minutes after the meal is the best time to consume probiotics.
