Why does Enfamil Gentlease taste bitter?

Enfamil Gentlease may taste bitter due to the specific formulation of its protein sources, which include partially hydrolyzed proteins designed to be easier for infants to digest. The bitterness can also arise from the presence of certain nutrients, flavoring agents, or ingredients that are necessary for the formula's nutritional profile. Additionally, individual taste perception can vary, and some babies may be more sensitive to certain flavors.
