The smell and colour of a baby's stools can vary due to factors such as fluid intake, iron intake and illnesses. Green stools are common for infants fed iron-fortified formulas with whey-predominant protein, such as NAN® HA.
The probiotics (bifidobacteria) in NAN® HA help create a gut environment with a pH of less than
7.3 and this gut environment (similar to that of
a breastfed baby) can make the colour of the baby's stool green.
The most important thing is not the stool colour but that NAN® HA is well-tolerated and is proven to support healthy growth and development.
