Digestive Enzymes help the body break down foods for better absorption so are great for those with digestion issues. The Enzymes included are as follows:
Alpha-amylase - Helps by starting the digestion process by breaking down carbohydrates
Neutral protease - Breaks down many forms of proteins which mean it is absorbed more efficiently within the body
Lactase - Used to aid persons with a lactose intolerance, assisting the digestion of dairy products
Lipase - This is key for the digestion of fats which some say can also promote weight loss. Other benefits include lessening the symptoms of IBS and boosting nutrient absorption.
