Source Naturals L-Proline Powder

Source Naturals L-Proline Powder is an amino acid valuable for the synthesis of collagen and cartilage to promote joint health and healthy skeletal muscle functions. Vegan diet, low-protein diet, and normal ageing process may reduce the body’s production of this non-essential amino acid. During these cases, additional supply of L-Proline should be acquired from the diet or L-Proline supplements.

  • L-Proline naturally contributes to healthy and strong joints by stimulating collagen synthesis. Collagen is the primary protein component of connective tissues in the joints like cartilages, tendons, and ligaments. Low levels of Proline may increase your risk of wearing and tearing of these connective tissues, a major risk factor for the development of joint problems like arthritis. By improving joint resiliency, L-Proline may help restore healthy joint functions in people with arthritis for relieve of pain, swelling, and immobility. Additionally, L-Proline is involved in maintaining the structure of bone cells for optimum joint care.
  • L-Proline aids in reducing the negative effects of atherosclerosis to cardiovascular health. Atherosclerosis is a condition where cholesterol forms plaques in the arterial walls, causing reduced flexibility of the arteries and blocking blood circulation. Atherosclerosis is a leading cause of the most common cardiovascular diseases like Coronary Artery Disease (CAD), hypertension, heart attack, and stroke.
  • L-Proline aids effective protein metabolism to help form new and healthy muscle tissues. L-Proline supplements can be used by athletes and bodybuilders to supply the lost Proline during extended periods of intense physical activities like running, swimming, and biking. During exercise, the muscles are being metabolised to produce energy in case the body’s glucose supply is not enough. L-Proline supplements appear to spare the muscles, protecting them from being broken down. Furthermore, this amino acid may assist with healthy muscle repair from the strain and soreness after extreme physical activities.

Proline is one of the non-essential amino acids, the ones the body can produce on its own without relying on nutrition. L-Proline is the form used to synthesise collagen and other connective tissues. Proline feature a unique molecular structure, entirely different from the other 20 amino acids that makes it vastly essential for the synthesis of enzymes and hormones that perform important functions in the body. Proline deficiency is rare, but it may occur in people who consume less or no protein in their vegan or low-protein diet. Additionally, the body produces lesser Proline as a result of the normal ageing process. Proline deficiency due to ageing can be accounted to the numerous joint and bone disorders that often occur in older people. During these conditions, Proline becomes a conditionally essential amino acid. Meaning, it should be derived from food sources and Proline supplements to correct the potential deficiency and prevent its health risks.
