There are deficiencies in Proline. Deficiencies have been noted in endurance runners and those who do prolonged exercises. These populations can benefit from supplementation in order to prevent muscle loss. When glucose is low, the body “eats” muscles for energy. Deficiencies of Proline have also been noted in those who suffer from an injury that is traumatic, skin injuries, especially severe burns, and people with pain that is caused by low amounts of cartilage or collagen formation could also benefit from these supplements.

There are a few sources of Proline, It is however, found in meat and dairy products. It is also found in eggs. If there are any questions about whether one should take the supplements, a physician should be consulted. The forms of the supplement are stand alone capsules, tablets, and the amino acid is often found in various sports drinks.

Some precautions should be taken in regard to Proline. Those with liver and/or kidney disease should not use this product with out talking to their physicians. Too much amino acid can throw off the balance of the citric acid cycle. It also tends to make the liver and the kidneys work harder to eliminate wastes.

Nutritional supplements in the U.S. and now other places 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 buying a product that actually contains the amount of ingredients stated on the product label, or worse still, a product that is not contaminated with harmful toxins.

Because of this, we suggest that you only purchase from pharmaceutical GMP compliant facilities, such places adhere to the most exacting manufacturing standards. If you do what we have suggested, you can be sure you are getting the amount of L-Proline you paid for, and one that is not potentially contaminated.
