Radiance Probiotic Baby Drops provides the clinically researched, infant dose of BB-12 in an easy to use, fridge free, oil drop format. Radiance Probiotic Baby Drops do not contain any superfluous ingredients such as silicon dioxide, sweeteners or flavours and uses only vitamin E and citric acid as preservatives. It was once thought that the digestive system of unborn infants is sterile. However, recent research suggests that microbial colonisation of the gut begins when the unborn baby swallows amniotic fluid containing microflora from the mother's gut. Unfortunately if the mother's flora is imbalanced due to poor diet, stress or antibiotic use this will be passed on to the infant before he or she is even born.
