Cortaflex® HA Super Fenn is specially formulated for competition horses or those in high work loads and as used by the City of London Police and those with excessive wear and tear to their joints.

Feed  15g  daily for maximum benefit  7.5g as a maintenance level.

Cortaflex® has been clinically tested in a double blind study of equine tarsal joint movement. The rigorous trial was conducted by the College of Veterinary Medicine at Michigan State University, one of the leading equine research institutes in the world. Unlike the more subjective research approaches in some equine trials, the study used advanced kinetic analysis techniques to objectively and accurately measure the horse’s gait. These techniques, based on video and force plates, unquestionably demonstrated the effects of supplementation. The results were then presented by the author Dr Hilary Clayton BVMS, PhD, MRCVS, to the American Association of Equine Practitioners (AAEP) and published in the conference proceedings.

Since the double blind study, HA & Silicon have been added to the formulation, these ingredients reflect more recent research in the support of equine joint comfort and mobility.  HA has been added for even greater benefit to the joints, particularly those that have experienced excessive wear and tear. HA is a major component of synovial fluid, which is essential for providing the joints with lubrication and the cartilage with nutrients. HA has traditionally been derived from type II Collagen sourced from Rooster Comb, which has a high molecular weight of up to six million Daltons.

This form of HA has been shown to be very effective when injected but is not considered to achieve a good rate of absorption when taken orally due to the large molecular size. The HA used in Cortaflex® is of vegetable origin and has a molecular weight of less than 50,000 Daltons.  It is believed that this is more readily absorbed, providing HA to the joints in a non-invasive way.

A complementary feedstuff for exercising horses designed to help support and maintain healthy joints as part of a balanced diet.
