Use
Growth of muscles, mainly achieved through the following aspects:
Provide the necessary nitrogen source for the body, promote muscle intracellular protein into the whole; compatibilization of cells and promote the growth and differentiation of muscle cells; stimulate the secretion of growth hormone, insulin and testosterone, the body is synthesized state.
Increase strength, improve endurance.
Important fuel of the immune system, enhance immune system function.
Involved in the synthesis of the valley walking on glutathione (an important antioxidant).
The gastrointestinal lumen basic energy source of the cell.
Improve brain function.
To maintain the normal function of the kidneys, pancreas, gallbladder and liver.
