Traditionally, collagen has been produced from bovine and porcine sources such as skin and tendon.

More recently collagen has also been produced from marine sources and protein substitutes derived from plants that are provided as collagen. Bovine collagen in particular has become less desirable due to safety issues surrounding transmissible spongiform encephalopathies.
