Specific enzymes work on specific foods. You need            the right type of enzyme for the foods you want it to break down. Think            of the foods you have problems with and then choose a product that contains            at least those types of enzymes. Here is a list of the common enzyme            types and foods they act on.
Digestive enzymes are enzymes that break down food            into usable material. The major different types of digestive enzymes            are:
• amylase – breaks down carbohydrates,            starches, and sugars which are prevalent in potatoes, fruits, vegetables,            and many snack foods
• lactase – breaks down lactose              (milk sugars)
• diastase – digests vegetable starch
• sucrase – digests complex sugars and starches
• maltase – digests disaccharides to monosaccharides (malt              sugars)
• invertase – breaks down sucrose (table sugar)
• glucoamylase – breaks down starch to glucose
• alpha-glactosidase – facilitates digestion of beans,              legumes, seeds,
roots, soy products, and underground stems
• protease – breaks down proteins found            in meats, nuts, eggs, and cheese
• pepsin – breaks down proteins into              peptides
• peptidase – breaks down small peptide proteins to amino              acids
• trypsin – derived from animal pancreas, breaks down              proteins
• alpha – chymotrypsin, an animal-derived enzyme, breaks              down proteins
• bromelain – derived from pineapple, breaks down a broad              spectrum of proteins, has anti-inflammatory properties, effective              over very wide pH range
• papain – derived from raw papaya, broad range of substrates              and pH, works well breaking down small and large proteins
• lipase – breaks down fats found in most            dairy products, nuts, oils, and meat
• cellulase – breaks down cellulose, plant            fiber; not found in humans
• other stuff
• betaine HCL – increases the              hydrochloric acid content of the upper digestive system; activates              the protein digesting enzyme pepsin in the stomach (does not influence              plant- or fungal-derived enzymes)
• CereCalase™ – a unique cellulase complex from              National Enzyme Company that maximizes fiber and cereal digestion              and absorption of essential minerals; an exclusive blend of synergistic              phytase, hemicellulase, and beta-glucanase
• endoprotease – cleaves peptide bonds from the interior              of peptide chains
• exoprotease – cleaves off amino acids from the ends              of peptide chains
• extract of ox bile – an animal-derived enzyme, stimulates              the intestine to move
• fructooligosaccharides (FOS) – helps support the growth              of friendly intestinal microbes, also inhibits the growth of harmful              species
• L-glutamic acid – activates the protein digesting enzyme              pepsin in the stomach
• lysozyme – an animal-derived enzyme, and a component              of every lung cell; lysozyme is very important in the control of infections,              attacks invading bacterial and viruses
• papayotin – from papaya
