L-Proline (Free-form USP grade)

99.87% pure pharmaceutical grade for maximum bioavailability.
No fillers, excipients or additives.

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.

Proline, along with the amino acid lysine and Vitamin C, is essential for the formation of healthy collagen and cartilage. It maintains the flexibility of both muscles and joints, and helps reduce sagging and wrinkling that accompany UV exposure and normal aging of the skin. Proline is also beneficial in the formation of bone, skin and cartilage and it is of paramount importance for the proper functioning of joints and tendons.

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.

All ingredients undergo state-of-the-art analysis to insure zero tolerance for impurities.

Truthful and Clear Supplement Facts Panels - No BS Proprietary Blends:

A proprietary blend is a cheap gimmick used by manufacturers to hide the real truth about what's in their product. By listing a bunch of ingredients under one blend on the label, the manufacturer only has to tell you how much of the blend is in a serving while hiding how much of each ingredient is in a serving. They pretend to this to protect their secret formula, that’s bull, they do it so they can cheapen their product without their customers knowing. In the industry we call this “Window Dressing” the product the label looks good on the outside but there is nothing really happening on the inside. At NutraBio our Supplement Facts panels list the exact amount of each and every active ingredient in the supplement. No guessing, you know exactly what you are getting in every product we sell.

Purchase manufacturer direct at wholesale price:

Buy directly from the manufacturer and save. We cut out the middlemen and pass the savings on to you. With NutraBio, you pay the same low wholesale price that the chain stores pay. Did you know that most companies do not manufacture their products but use 3rd party manufacturers? Since we manufacture all of our own products we can control the quality and purity through the entire manufacturing process. We never sell old or near expired products.
