Why proline is good for you
Proline is a non-essential amino acid, as it can be synthesised from glutamic acid, so it is not required to be obtained from dietary sources.
Proline improves skin texture by aiding in the production of collagen and reduces the loss of collagen through the aging process. Proline works with vitamin C to promote healthy connective tissue. Proline also helps in the maintenance and healing of cartilage and the strengthening of joints, tendons, and muscles (including the heart muscle).
Important proline facts

- Proline helps vitamin C produce collagen. Together with vitamin C, proline boosts collagen production a boost
- Collagen is composed of the metabolic by-product of proline called hydroxyproline
- Proline helps with the maintenance and regulation of cartilage production and helps to heal cartilage tissue if it is injured or damaged in any way
- Proline helps the body heal the tissues damaged after accident or injury, so it is very useful in wound healing
