Proline, also known as L-Proline, is an amino acid. It is non-essential because it can be synthesized by the body through the breakdown of L-Glutamate (another amino acid). Protein is broken down into amino acids, or building blocks. If you consume an adequate amount of protein in your diet, your body will have the right amount of amino acids it needs to produce Proline, an important compound responsible for tissue repair, collagen formation, arteriosclerosis prevention and blood pressure maintenance.
Proline aids the body in breaking down proteins for use in healthy cells. In conjunction with Lysine, another amino acid, Proline is a precursor for Hydroxyproline and Hydroxylysine. The body uses Hydroxyproline to make collagen, tendons, ligaments and heart muscle.
