Trophic Digest-Aid Bile Salts - Contains bile extract and three digestive enzymes, lipase, trypsin and bromelain. The herbs chamomile and goldenseal and the mineral charcoal have been added to further aid the digestive process. In the formula, lipase splits fats into two compounds: glycerin and fatty acids. Tryspin and bromelain are powerful protecolytic enzymes that digest proteins more rapidly and completely than pepsin. Goldenseal is traditionally used to soothe the mucous membranes of the digestive tract and aids with difficult digestion and dyspepsia. The bile salts are probably formed throughout the body, but are concentrated in the liver and excreted throughout the bile duct into the duodenum. There, they play an essential role in the digestion of fat.
