NOW L-Proline


The non-essential amino acid, L-Proline, is involved in protein synthesis. L-Proline is an amino acid that is essential for the synthesis of collagen, the most abundant protein in mammals. Collagen is the main structural protein that constitutes all human connective tissues, including skin, tendons, ligaments, joints, bone, and vasculature (veins and arteries). L-Proline therefore provides building blocks that help to stabilize and strengthen the structural components of the body. Although L-Proline can be made in the body, low protein and vegetarian diets may not provide optimal support for the production of collagen.


L-Proline is a non-essential amino acid that can be produced naturally in the body. But often individuals may suffer from insufficient uptake of the dietary nutrients needed to synthesize it. The amino acid can be found in meat and certain animal products, or it can be taken in through supplements. It is one of the 20 amino acids that help form proteins, one of the main one’s being collagen. It is also involved in energy production within the muscle when muscle glycogen sources are low, which occurs often in endurance athletes or during heavy training cycles. L-Proline plays a role in joint and bone health, skin health, and muscle energy function helping preserve muscle tissue. NOW® L-Proline 500mg is a high potency source of free-form L-Proline and is delivered in vegetarian capsules making it suitable for vegans and vegetarians.
