Why is animal collagen different from plant collagen?
Collagens can be classified as being of animal or plant origin. Animal collagen is extracted from bovine and porcine bone or skin. Plant collagen is made by modifying polysaccharides (natto gum) through fermentation of yeast. Plant collagens used in cosmetics are heated and denatured simple proteins in the form of gelatins, which may exist at room temperature. They are biologically inactive. True active collagen must retain its molecular integrity at cold temperatures to be able to impact cell function. Refrigerated animal source collagen is the most viable therapeutic collagen with all of its properties intact. This makes it a superior product to plant collagen. PURGLO products always use safe porcine-animal source collagen, to ensure superior bioactivity.
