L-Hydroxyproline

Product Details

L-Hydroxyproline is a nonessential amino acid, which means that it is manufactured from other amino acids in the liver; it does not have to be obtained directly through the diet.

L-Hydroxyproline is necessary for the construction of the body's major structural protein, collagen.

L-Hydroxyproline can improve the flavor and quality of fruit juice drinks, soft drinks, etc.

L-Hydroxyproline gives strength to the protein collagen in the bones, tendons, cartilage and skin.

Is produced by hydroxylation (adding hydroxil or [OH] groups) of proline, with the help of vitamin C. In vitamin C deficiency, proline cannot be converted to hydroxyproline, so collagen does not have enough strength to maintain skin integrity.
