L-lysine is an essential amino acid that is a necessary building block for all protein in the body. L-Proline

is a major amino acid found in cartilage and is important for maintaining youthful skin, proper functioning

of joints and tendons and helping to maintain and strengthen the heart muscle. Without adequate

protein, your body cannot build the structures that make up your cells, tissues and organs,

nor can it generate the biochemical substances it needs for cardiovascular

function, muscle contraction and immune support.
