Proline is a non-essential amino acid that aids in the production of collagen and helps reduce the loss of collagen due to the aging process.
Proline is considered non-essential because our bodies can synthesize proline. Proline is one of 20 amino acids used to make mammalian proteins and makes up a large part of the connective protein collagen. Proline has a unique structure that allow the collagen to pivot at its center, giving the portion around it the flexibility it needs. Proline is also in high concentrations in other connective tissues, hair, skin and nails.
Proline is listed in the U.S.P. and can be found in products specifically to help connective tissue, joint or skin conditions.
Proline has anti-aging properties; heals cartilage, strengthens joints and tendons; improves elasticity of and strengthens the heart muscle.

Proline is involved in the structural repair of damaged collagen in arteriosclerotic blood vessels (hardened arteries).
