L-Proline is an essential amino acid and precursor, along with vitamin C, of collagen. Collagen is a building block of tendons, ligaments, arteries, veins, and muscles (heart muscle). It is important in wound healing, building cartilage, and supporting flexible joints and muscles. The amino acid also helps reduce sagging, wrinkles, and skin aging due to sun exposure.
L-Proline breaks down proteins to help create healthy cells. The amino acid is essential for healthy skin. It is also essential for creating healthy connective tissues. Collagen helps heal cartilage and cushion joints and vertebrae. The amino acid also maintains muscle tissue.
L-proline deficiencies
There are deficiencies in Proline. Deficiencies have been observed in endurance runners and those who engage in prolonged exercise. These populations may benefit from supplementation to prevent loss of muscle mass. When glucose is low, the body “eats” the muscles for energy. Proline deficiencies have also been observed in those suffering from traumatic injury, skin injuries, especially severe burns, and people with pain caused by low amounts of cartilage or collagen formation might also benefit from these supplements.
There are a few sources of proline, however it is found in meat and dairy products. It is also found in eggs. If there is any question as to whether the supplements should be taken, a doctor should be consulted. Supplement forms are stand-alone capsules, tablets, and the amino acid is often found in various sports drinks.
Some precautions should be taken regarding Proline. People with liver and/or kidney disease should not use this product without consulting their doctors. Too many amino acids can upset the balance of the citric acid cycle. It also tends to make the liver and kidneys work harder to remove waste.
Our advice for choosing an L-proline supplement
Nutritional supplements in the US and now elsewhere in the world are largely unregulated, and many parties, both government and private, have determined that health consumers only have a 1 in 5 chance of purchasing a supplement. product that actually contains the amount of ingredients stated on the product label, or worse yet, a product that is not contaminated with harmful toxins.
Because of this, we suggest that you only buy from GMP-compliant pharmaceutical facilities, which adhere to the highest manufacturing standards. If you do what we suggest, you can be sure that you are getting the amount of L-proline you paid for and that it is not potentially contaminated.
