5-HTP may be useful if you are overweight as many believe that weight gain may be caused by decreased amounts of tryptophan to 5-HTP, which causes low serotonin levels, which may cause constant hunger. Adding 5-HTP to your diet may reduce this deficiency and remove these feelings of hunger.

Amylase is also sometimes called a starch blocker. As the name suggests, it prevents the body from absorbing dietary starches. It is present in the saliva. This is particularly benefits diabetic patients because it helps maintain and regulate the blood glucose levels. It also helps in maintaining and losing weight. It is effective in treating obesity. The ingested carbohydrates are broken down by the digestive enzymes which are then absorbed by the body. Amylase limits the capacity of the body in absorbing carbohydrates which are later on turned into glucose, a simple sugar, that can be used by the body as energy fuel.

Cellulase breaks down fibers. The term cellulase refers to a group of enzymes that target breakdown of cellulose, which is the most abundant and primary structural content of vascular plants. The body cannot digest cellulose, but supplemental cellulase can be consumed to help the breakdown of cellulose into beta-glucose. For producing supplemental cellulase, a nonpathogenic and nontoxicogenic species of fungus, Trichoderma viride, is cultured, from which cellulase is obtained and purified. Beta-glucose has viscous quality in intestinal canal and stomach, and its resistant quality slows down absorption of fats and carbohydrates from food sources. This ensures a positive effect by assisting in maintaining steadier blood levels of cholesterol and sugar after eating.

Lipase is an enzyme secreted by the pancreas to stimulate the breakdown of fats ingested into fatty acids, which are then absorbed in the intestines. This fat-splitting enzyme is found in the blood, gastric juices, pancreatic secretions, intestinal juices and adipose tissues and hydrolyzes triglycerides into fatty acids and glycerol. Generally, people produce adequate amounts of lipase thereby not needing supplementation of such enzyme. But persons with Crohn’s disease, Cystic fibrosis, and celiac disease may not have sufficient lipase to acquire the nutrients from their food and additional lipase would be helpful. In cases of indigestion, supplements containing lipase and other pancreatic enzymes aided in reducing gas, the feeling of fullness and bloating after eating a meal high in fat. Lipase supplements are not to be given to children under 12 years of age. Nausea and stomach upset may occur as side effects and drug interactions with orlistat may render lipase enzymes inactive as orlistat blocks lipase from breaking down fats. Digestive enzymes like pepsin, betaine HCl, HCl and papain can destroy lipase enzymes; do not take these in with lipase supplements.

Magnesium is the chemical element found in the periodic table with the atomic number 12. This alkaline earth metal is one of ten most common elements in the known universe and also very prominently present in the human body. It manipulates polyphosphate compounds, most prominently the DNA, RNA and the ATP. Numerous enzymes rely on magnesium ions to function properly. Most common application of magnesium in medicine may be the addition to antacids and laxatives. This metal is not found as a free element naturally on Earth, generally the metal is obtained through electrolysis of magnesium salts. The most common deficiency in the United States with staggering two thirds of the population is the magnesium deficiency. Magnesium can be obtained through vegetables, tea, cocoa, cereals, coffee, nuts and spices.

Melatonin- Main function is to keep the biological clock in humans synchronized but also has a powerful antioxidant quality. Can be important in body building to fight toxins.

Phytase is an enzyme that is normally produced in ruminants such as cattle, goat, and sheep. Phytase help the body break down phytic acid found in grains and oil seeds which are normally indigestible for non-ruminants such as humans and dogs. This helps release phosphorus, magnesium, calcium and other nutrients that the body needs. Phytase may be commercially produced by microbial fermentation. Phytase help in ensuring that nutrients, vitamins, and minerals are properly utilized by the body. It helps release phosphorus which plays an important role for bone growth. It also reduces the risks of heavy metal poisoning which may be caused by Dicalcium phosphate.

Protease is an enzyme that reduces inflammation. Inflammation is the body's natural response to injury, but increased inflammation retards healing process. It cleanses the blood of organic debris. Protease helps dissolve fibrin in the blood, reducing the risk of clots. Different specialized proteases like nattokinase are good at bettering quality of blood cells, reducing risk of clots, and optimizing ability of blood to flow through circulatory system. This helps decrease risk of stroke. It strengthens the immune system and kills viruses, bacteria, fungi, and molds. Protease eliminates autoimmune diseases. It helps dissolve scar tissue, which is made of protein. Proteolytic enzymes effectively dissolve scar tissue, especially in circulatory system. It can help decrease symptoms of MS, cleanse lungs and assist in detoxing.

Valerian Root is a perennial plant, which can bloom into pink and white flowers that have a scent perceived as sweetly. It can be found in Europe and some areas in Asia, recently also in North America, where it has been imported. The sedative and anxiolytic properties of the valerian roots have been known to mankind for centuries. Valerian root extracts contain many pharmacologically active substances, some which are valeric acid, GABA, isovaleramide, valerine, valerianine, actinidine, an essential oil that contains sesquiterpenes, and many more. Since that valerian has been used as a pain reliever, anti convulsant, a sedative and for migraine treatment, the primary use has been always related to the GABA receptor system. It has been recommended as a potent sleeping agent.
