L-proline (referred to as proline) is one of the 20 kinds of amino acids that the human body synthesizes protein. It is colorless to white crystal or crystalline powder at room temperature. It has a slight odor and a slightly sweet taste. It is easily soluble in water. Amino acid is a general term for a class of organic compounds containing amino and carboxyl groups. The presence of amino acids in the human body not only provides important raw materials for protein synthesis, but also provides a material basis for promoting growth, normal metabolism, and maintaining life.
Promote muscle growth: proline can promote the synthesis and repair of muscle, and supplement the appropriate amount of proline after exercise can help the body recover and strengthen muscle strength. In addition, proline can also help maintain muscle mass by increasing protein intake and help prevent muscle atrophy
Boost immunity: Proline is an essential amino acid that is essential for the proper functioning of the immune system. It can stimulate the production of white blood cells, thereby enhancing the body's resistance to disease. At the same time, proline is also involved in many important physiological processes, such as tissue repair and wound healing
