A review of all clinical studies confirmed that prebiotics are associated with a reduction in eczema and allergy in infants. Prebiotics are nutrients that feed the growth of healthy intestinal bacteria. These include oligosaccharides and inulin from various plant sources.
The supplements evaluated in these studies were galacto- and fructo-oligosaccharides. (GOS and FOS). These prebiotics are frequently added to probiotic formulas by many manufacturers. And they are available with other immune enhancing product formulas.
Infants at high risk of allergies who took prebiotics had a significant reduction in asthma and eczema, and infants regardless of their risk had a reduction in eczema.
Supplementing infants with prebiotics and probiotics is beneficial for reduction of eczema and asthma incidence.
