L-Proline is an amino acid involved in the production of collagen and cartilage and may help support healthy joints and a healthy musculoskeletal system. Proline is the only precursor to hydroxyproline, an essential component in the production of collagen, the ‘cement’ which holds together the skin, cartilage, ligaments, tendons and arteries. Collagen production decreases significantly with age and is the source of a number of serious degenerative diseases. Proline supplementation is essential for restoring normal collagen production.

L-Proline can be made in the body, but low protein diets and vegetarian diets may not promote optimal Proline production. Proline is found mainly in meat which can be synthesized by the body under certain conditions. The body's ability to break down protein into proline and other amino acids differs based on factors such as diet, illness, stress, old age, and its inability to secrete digestive enzymes. By supplementing your diet with pure amino acids, you are saving your body the necessary step of breaking down dietary protein to obtain these amino acids. NutraBio's Proline is pharmaceutical grade free form proline which has the advantage that it can be directly absorbed providing maximum bioavailability.

In 1989, Linus Pauling (who won the Nobel Prize in chemistry) found that atherosclerotic plaques are not the cause of cardiovascular disease but a means by which the body strengthens arterial walls weakened by a lack of collagen due mainly to chronic vitamin C deficiency. To reduce atherosclerotic plaques, Pauling recommended taking at least three to five grams of vitamin C a day and at least three grams a day each of lysine and proline. These two amino acids are natural chelators of certain lipoproteins that are the main ingredient in plaque. Subsequent studies conducted by Dr. Mathias Rath have confirmed Pauling’s recommendations and have enabled thousands of patients to avoid angioplasty and open-heart surgery.
