Dicalcium phosphate - a combination of phosphorus and calcium (classified as macronutrients) in a single molecule. Calcium is the building substance of bones, teeth and activator of enzymes, including ATP-ers release ATP energy. It affects the blood clotting and muscle-nerve conduction. Phosphorus, besides a common feature with calcium- the bone structure, conditioning their development and normal condition, and also affects the formation of nucleic acids and brain tissue. It stimulates the acid-base. It participates in the processes of energy (phosphorylation) and phosphocreatine synthesis. Calcium phosphate is used in supplementation, as the ingredient of mineralizing, vitamin-mineral and pre- and post-workout supplements.
