Probiotics are useful for newborn jaundice. After oral administration of probiotics, they help establish a normal gut microbiota in babies and then reduce the enterohepatic circulation of bilirubin, which aids in the treatment of jaundice. Common probiotics, often referred to in layman's terms as live bacteria, include species like Saccharomyces boulardii, Bifidobacterium, or Lactobacillus, among others. These probiotics are available in pharmacies. Generally, for newborns, especially those who are breastfed and do not recover well from jaundice, oral probiotics can have a therapeutic effect on reducing jaundice, so it is suitable for newborn babies to consume certain probiotics.
