Amylase works on carbohydrate and lipase is the fat-breaking enzyme.
Veterinarians advise that it is important to use supplements with a balanced formula of enzymes.
Subsequent research has confirmed his original conclusions. Such substances absorbed intact from the gut can cause disturbances in the body. This necessitates large dosages and greater expense for efficacy. Aspergillis lipase, by comparison, is resistant to inactivation by gastric acidity. Aspergillis enzymes are used worldwide.
