Mammalian-derived collagen is genetically closest to humans and therefore, least likely to cause allergy or rejection. It is necessary to draw collagen from big mammals such as; sheep, pigs and cows that can be cultivated domestically in large numbers.

Collagen is the major structural protein found in human connective tissue and is widely accepted as a safe and natural bio-material for the manufacture of a broad range of medical products.

As a result of the global epidemic known as "Mad Cow Disease" and todays more recent outbreaks of the more correctly known Bovine Spongiform Encephalopathy (BSE), there is a definite market need for a safe and acceptable collagen source to replace the bovine collagen used in existing healthcare products.

Ovine (sheep) Collagen obtained from an isolated disease-free flock in Australia is the most culturally acceptable collagen. It has many advantages over bovine, marine or porcine sourced collagen. OviGenex is safe and fully traceable from the farm. OviGenex collagen is acceptable to most cultures (including Islam and Hindu) as opposed to porcine and bovine collagens.
