Like gelatine, hydrolysed collagen is made by hydrolysis process from Type 1 collagen. The same collagen as that found in human bones and skin. It is a natural product containing more than 97 % protein (on a dry weight basis hydrolysed collagen contains 18 amino-acids, including 8 out of 9 essential amino-acids. It is characterized by the predominance of glycine, proline and hydroxyproline, which represent around 50 % of the total amino-acid content. This specific composition of amino-acids provides hydrolysed collagen with functional properties that cannot be found with other protein sources.

Now it has been scientifically proven that 10 grams of hydrolysed collagen per day meet the daily requirements of an adult to enjoy benefits on joint, bone and skin health. Hydrolysed collagen has become a key ingredient for the nutraceutical (functional foods, beverages, dietary supplements) and cosmetic industries.

A valuable source of protein, it is also particularly relevant for high protein diets and sports nutrition.
