Proline

Your body uses the amino acid proline to build collagen. Collagen makes up the tough, elastic fibers of scar tissue and is the main structural material of your body.

Bones, tendons, ligaments, and skin all contain collagen. A sufficient amount of this amino acid promotes healthy bones, skin, and cartilage.

The production of collagen also improves skin texture. As we age, we tend to produce less collagen, leading to fine lines and wrinkles. Proline aids in the aging process.

Proline is best taken with vitamin C. Both the amino acid and the vitamin are effective in healing injuries and strengthening tissues.
