Answer by Dr. Ru: About Lactase usage in lactation

Enzyme which is composed by more than 1.000 amino acids that hydrolyzes Lactose into Glucose and Galactose. It is produced in larger quantity by intestinal cells of newborns and infants than older children and adults, in order to digest the milk sugar or Lactose. Depending on type of populations, only 30 to 70% of individuals can continue producing intestinal lactose in later ages. At latest update information was not found on excretion into breast milk, but, because it's proteic nature it would be digested before absorption, all that along with a high molecular weight makes excretion intro breast milk highly unlikely. In addition, it is not toxic since it has been used, with no effectiveness, for treatment of colicky pain in infants without side-effects reported.
