What makes Cortaflex different to other joint supplements?

Chondroitin and Glucosamine are produced naturally by the body and aid in repair and maintenance of the joint tissue. Joint cartilage is not directly connected to any blood vessels so, all of the nutrients that the cartilage needs for good health have to be small enough to pass through cellular walls to benefit the joint tissue.

Cortaflex was formulated around the theory that smaller molecules are more likely to be absorbed through cellular walls than larger ones. Therefore, Cortaflex contains the micro sized key active isolates of Chondroitin and Glucosamine, providing the body with both the building blocks and the stimulus for its own production of Chondroitin and Glucosamine.

Cortaflex is now fortified with Hyaluronic Acid (HA) for even greater benefit to the joints, particularly for hard working horses. 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 taking orally due to the large molecular size.

The Hyaluronic Acid used in Cortaflex is of vegetable origin and has a molecular weight of less then 50,000 Daltons. It is believed that this is more readily absorbed, providing Hyaluronic Acid to the joints in a non-invasive way.

Clinical Study

Cortaflex is the only equine joint supplement to have been clinically proven 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 the majority of equine trials, the study used the most advanced kinetic analysis techniques to objectively and accurately measure the horses gait. These techniques, based on video and force plates, unquestionably proved 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.

Chondroitin or Glucosamine? Both? or Cortaflex?

Chondroitin and Glucosamine are widely believed to stimulate the joint cells to produce better quality joint fluid (synovial fluid, which acts as a cushion), and to trigger the cartilage matrix to help prevent damage to the joints.

Cortaflex is an effective joint supplement because it contains the key refined, pharmaceutical-grade isolates of Chondroitin and Glucosamine. These smaller molecules are easily absorbed into the bloodstream, where they filter through the capillaries to their intended destination – the joints! Once the key isolates are present in the joints, they trigger the body to produce its own natural Chondroitin and Glucosamine. Cortaflex provides both the stimulus and building blocks for natural joint health – that is the Cortaflex difference! Cortaflex has been clinically proven in the equine world to improve joint function.

How is Cortaflex different from other Glucosamine and Chondroitin products?

Cortaflex is beyond Glucosamine and Chondroitin! Molecules of Glucosamine and Chondroitin, even in their purest form, are simply too large to travel efficiently to the soft tissues of the joint. Instead of loading Cortaflex with thousands of milligrams of Glucosamine and Chondroitin, we have specially formulated our product using their key isolates: Glutamine, Glutamic Acid, Glucuronic Acid, Glycine, Proline The unique formulation of Cortaflex allows these building blocks, assisted by Sulphur, to be more readily absorbed by the body. We only use pharmaceutical grade ingredients in Cortaflex, so you are assured of getting a safe, natural, quality product.

What is Hyaluronic Acid?

Hyaluronic Acid (HA) is a major component of joint lubricating fluid, essential for absorbing concussion and providing cartilage with nutrients and lubrication for movement.


How long does Cortaflex need to be taken? Is it supposed to be administered as a course?

Cortaflex is a nutritional dietary joint supplement – not a medicine. As such, Cortaflex can be taken indefinitely! We believe that taking Cortaflex on a regular basis can help to protect joints from the stress and strain of modern daily life.

I don’t actually have any pain or trouble with my joints… is it ok for me to take Cortaflex anyway?

Cortaflex is safe for people of all ages and physical conditions! It is a joint supplement for natural joint health – not a medicine. If you are eager to maintain an active lifestyle, doing the things you love to do for as long as possible, then Cortaflex is for you.

Do I need to take Cortaflex at a specific time of the day, or with food?

Many people take Cortaflex at the same time every day, simply because it is easier to remember to take it! However, it is not necessary to take it at a specific time of day, nor is it necessary to take Cortaflex with food.

I am on other medication – can I take Cortaflex?

Cortaflex is not a medicine – it is an all-natural dietary supplement. There are no known side effects of Cortaflex, and there are no known contra-indications. We always advise you to consult your doctor if you have any concerns about prescribed medication.


I have a puppy whose pedigree makes it prone to joint problems, especially in the hips. I want to try and prevent any problems from developing, but is Cortaflex safe to give to a puppy?

Cortaflex is safe for dogs of all ages and physical conditions. It is a supplement for natural joint health. If you want your pets to maintain a happy, healthy life, then Cortaflex is the choice for you.
