L-Proline, provided by Douglas Laboratories supplies 500 mg of the amino acid L-proline in each capsule.

Amino acids are well known as the building blocks of the body. Amino acids are so important for growth, development and repair, that the body in many cases has developed mechanisms to allow it to produce some of the amino acids needed for health. There are however still some amino acids that must be supplied via your diet.

L-Proline is an amino acid that the body requires to be able to produce collagen and to be able to ensure the healthy formation of cartilage. It keeps muscles and joints flexible and helps reduce sagging and wrinkling that accompany UV exposure and normal aging of the skin.

A proline supplement is often a good way to help combat or reduce skin sagging and it may also help to prevent the normal wrinkling that can occur as a result of spending too much time in the sun. Proline supports the natural aging process of the skin to help to keep skin looking younger for longer.

Meat, dairy, and eggs are the best natural sources of proline; vegetarians or those with a low-protein diet should seriously consider a combination amino acid supplement containing, among other amino acids, proline. Douglas Laboratories' L-Proline amino acid supplement provides 500 mg of this important amino acid, designed to support the formation of collagen and to ensure healthy aging.
