Explaining Cortaflex


Cortaflex® includes vital trace elements and precursors (or building blocks) of key compounds such as glycosaminoglycans and proteoglycans which are necessary for the production and maintenance of healthy cartilage and joint fluid, which also plays an important role in shock absorbing and lubrication within the joint.

Amino Acids

Amino acids such as glutamic acid - converted in the horse’s body to provide glutamine, which combines with glucose to form glucosamine – which itself then combines with other compounds to help give cartilage its flexibility and “sponginess”.

Copper, Manganese & Silicon

Are important trace elements which are all needed to help the horse produce his own chondroitin, (another important structural compound in cartilage), collagen and hyaluronic acid.


An important compound needed by the chondrocytes to produce the water based matrix of the cartilage. Collagen helps to give cartilage its strength. (We utilize a sustainable and ethical source of marine derived collagen.)

Hyaluronic Acid (HA)

Is a key component of joint fluid, which bathes the joint, and acts and a lubricant and shock absorber.


More recently, as well as providing these vital building blocks, MSM (methylsulphonylmethane ) has been added to the Cortaflex supplements, to provide a bio-available source of sulphur, which is important in the repair process of the sulphur containing bonds in the cartilage matrix. MSM is also thought to have anti-inflammatory properties.


Cortaflex Super Fenn also contains Boswellia, a plant known for its antiinflammatory properties, to help reduce the on-going destruction of cartilage following micro-trauma and the resulting inflammatory responses arising from harder work.
