If you want to do something good for your intestines after a period of unhealthy eating habits, it is usually enough to change your diet for about 2 weeks.

After taking antibiotics, however, it can take up to a month for your intestinal flora to regenerate with the right diet. Depending on how many complaints and how severe your complaints are, it can also take three to six months for your intestinal flora to build up.

How do I guarantee intestinal health in babies and toddlers?

A healthy intestinal flora is also important for the health of children. In general, the same nutritional strategy applies to them as to adults.

A study has also shown that the way the child was born has an influence on the intestinal flora of the child. It has been shown that children born by cesarean section do not have as good intestinal health as children born with natural birth.

It is therefore important to continue to build up the intestinal flora here. Unfortunately, it is often the case with premature babies that intestinal diseases or intestinal problems occur after birth. A recently published study from Switzerland showed that the oral increase in probiotics can also have a positive effect on intestinal health. After just two weeks, a significant improvement was seen as new microorganisms formed.

How do I guarantee gut health in pets?
