The importance of the microbiota in infants and children

The newborn infant establishes its gut bacteria and intestinal microbiota from the time of delivery and during the next three years. Directly after birth the newborn baby is almost sterile but very soon bacteria start colonizing every part of the body – the skin, the mouth and most importantly the gastrointestinal tract. The number and diversity of bacteria continue to increase until the age of three, when it resembles the composition in an adult and then, more or less, remains the same throughout life.

The interest in gut bacteria and the infant’s microbiota has exploded in recent years and research has shown that the infant microbiota plays an essential role in human health. A diverse microbiota may help the infant to optimize the development of the gastrointestinal tract and the immune system.

The microbiota contributes to:

  • Enforced gut barrier
  • Improved digestion
  • Improved gut motility
  • Development of the immune system
