Probiotics are microorganisms, mainly bacteria, that compare to those naturally found in your gut and promoted as having various health benefits. More than 70% of our immune system is found in our guts, in which 10 to 100 trillion microorganisms are inhabited, resulting in a complex and stable bacterial ecosystem. The total number of bacteria is ten times greater than the total number of cells in our body.
In children, things such as antibiotics prescribed for common problems such as an ear infection, can cause an imbalance of the good bacteria found in their guts. It is also recommended that pregnant women can benefit from taking these probiotics, as a healthier mother makes for a healthier baby. However, infants who are breastfed should refrain from taking probiotics due to bacteria that is already transmitted through breast milk.
