👉 Lactenin is a type of hormone that is produced in the liver during pregnancy to help the mother produce milk. It helps the baby absorb nutrients from breast milk and also regulates blood sugar levels in the body, which is important for healthy development. Lactaline is released into the bloodstream by the mother's placenta as part of the delivery process, but it can be produced in the body during pregnancy to help the mother produce milk when she has children.
