Proline is a non-essential amino acid that the body uses extensively in the production of collagen and other structural proteins. While the body can synthesise proline, demand may increase during periods of physical stress, ageing, injury or increased connective tissue turnover. Supplementing with proline provides targeted nutritional support for tissues that rely heavily on collagen for strength and elasticity.

Metabolics Proline is made with clarity, purity and purpose, delivering high grade L proline in a simple capsule with no unnecessary additives so it is easy to use in daily routines or practitioner guided protocols. Each UK made capsule contains only proline and a plant based shell, reflecting Metabolics wider amino acid range focus on clean, focused ingredients that support collagen and connective tissue from within without added complexity.

Proline is amino acid that plays a role in a number of functions within the body. It is considered a non-essential amino acid because the body can produce it from other compounds or amino acids, however we also obtain it from the diet, mostly through protein sources. Proline is required for the synthesis of collagen. Collagen is a crucial structural component in bones, cartilage, connective tissues (such as tendons) and skin; therefore, it is necessary for the maintenance of joint health.

Collagen has at its core a triple helix of amino acid chains; three chains wrapped around each other. Each chain is constructed from repetitions of x-y-gly three-amino-acid units, in which the X and Y positions are often occupied by prolines (and the gly is glycine). Proline constitutes about 12% of collagen.
