L-proline is an amino acid, which is a type of amino acid. L-proline is one of the “nonessential amino acids” due to the fact that the body is able to manufacture a certain amount of it on its own, but it’s still important to get the rest via foods such as beef, chicken, black beans and lentils or by taking L-proline supplements. Taking an L-Proline supplement becomes increasingly vital as we age, as our bodies make less and less of it over time. On a per gram basis, proline requirements are the highest of all amino acids for whole-body protein synthesis. Each Capsule of Swanson Amino Acid L-Proline contains 500 mg of L-Proline.
- CONNECTIVE TISSUE HEALTH – Collagen is the connective tissue that’s responsible for holding your bones together, reducing friction between bones and acts as a shock absorber during daily physical activities like walking. The human body produces collagen with the help of an amino acid known as hydroxylysine. L-proline is essential for collagen because it is the pre-cursor to hydroxylysine.
- INTESTINAL HEALTH – Having a healthy digestive system is vital. Proline is a major nitrogen source for the intestinal cells. These cells have high turnover, which elevates their overall nitrogen needs.
- ANTIOXIDANT SUPPORT – L-proline also has the ability to scavenge free radicals. This helps provide antioxidant support under conditions of oxidative stress.
