The new LAMBERTS Lactase Complex 350 mg is equivalent to 9000 FCC Food Chemical Codex, which makes it one of the highest concentration products. The function of the digestive system is to digest food and absorb the nutrients found in it. If this process is not done efficiently, it is unlikely that our health will be in an optimal state, regardless of the quality of our diet. Enzymes must first break down ingested food into their respective constituent molecules so that they can be absorbed in the small intestine. The efficient disintegration of food is essential to release vital nutrients that must then be absorbed through the intestinal wall, through complex biochemical processes. Lactase is a digestive enzyme necessary to break down lactose, the sugar in milk. Lactase should be synthesized by the body in the small intestine.
