Why Cortaflex? Simply because it's more than just glucosamine and chondroitin!

Equine America Cortaflex for joints is an effective dietary supplement or nutritional supplement for joint issues. A clinical study has been conducted to prove the efficacy of Cortaflex. The product is available worldwide and has been recording excellent results, with numerous satisfied customers also attesting to its effectiveness in the Slovenian market.

In our store, you can find Cortaflex for dogs as well as for horses.

The body naturally produces glucosamine and chondroitin, which play a vital role in repairing and maintaining joint tissue – cartilage and synovial fluid. Because cartilage is not directly connected to blood vessels, it’s difficult for it to receive all the nutrients it needs for good health. To pass through cell walls and benefit the joints, nutrients must be small enough. The product is based on the theory that smaller molecules can more easily penetrate cell walls than larger ones. Since the body cannot efficiently utilize larger molecules of chondroitin and glucosamine due to limited passage from the bloodstream, Cortaflex contains smaller (micro) molecules that effectively pass from the bloodstream into soft joint tissue. This is crucial because large molecules of chondroitin and glucosamine, typically present in other supplements of this kind, are significantly less absorbed. We have also added plant-derived hyaluronic acid (in some products, a hyaluronic acid booster) and MSM to all Cortaflex products. Thus, Cortaflex, composed of the basic building blocks of chondroitin and glucosamine: glutamine, glutamic acid, glucuronic acid, proline, and glycine, delivers essential nutrients through the bloodstream throughout the body.

Cortaflex is fortified with hyaluronic acid (HA) for even better joint support, especially for those experiencing excessive joint wear and tear. Hyaluronic acid is a key component of mammalian joint fluid or synovial fluid, which restores the highly elastic properties of joint fluid and improves joint mobility. HA is traditionally derived from type II collagen sourced from rooster combs, which has a high molecular weight of up to six million daltons. However, due to the poor absorption of animal-derived hyaluronic acid when ingested because of its high molecular weight, we use plant-derived hyaluronic acid in Cortaflex for dogs and cats. Its significantly lower molecular weight allows for better absorption. 


As animals age, normal wear and tear on their joints occur, but our domestication of animals has only increased the pressures on their joints, leading to a rise in various musculoskeletal disorders. Limping is a common occurrence and often the leading cause for a dog or horse to withdraw from training. Adding a proven dietary supplement can significantly contribute to restoring balance and supporting healthy joints.

While joint issues cannot be completely eliminated, the best measures to slow down and alleviate diseases involve early care with proper nutrition, adding appropriate dietary supplements, and regular physical activity for animals. Opinions on the effectiveness of dietary supplements vary, but the efficacy of Cortaflex is demonstrated by research studies and the results of clinical trials.


Cortaflex is the only joint supplement clinically proven to work in a double-blind study of tarsal joint movement! A rigorous trial was conducted at the College of Veterinary Medicine at Michigan University, one of the world’s leading institutions in equine research. Unlike more subjective research approaches in most horse trials, this study utilized the most advanced kinetic analysis techniques for objective and precise measurement of horse gait. These techniques unequivocally demonstrated the effects of our supplement. The results were presented to the American Association of Equine Practitioners (AAEP).

Chondroitin and glucosamine positively affect joint cells, improve the quality of synovial fluid, and promote the formation of joint cartilage. Cortaflex is an effective joint supplement that contains essential building blocks (smaller molecules) of the highest quality of both chondroitin and glucosamine. These smaller molecules are easily absorbed into the bloodstream, where they travel from capillaries to their target – the joints. Once the basic building blocks reach the joints, the body begins to produce its own chondroitin and glucosamine.

Cortaflex surpasses glucosamine and chondroitin because its formulation does not contain large molecules of chondroitin and glucosamine, but rather their basic building blocks of chondroitin and glucosamine in smaller molecules. Why is it so important to have small molecules in the product? Large molecules of chondroitin and glucosamine, typically present in other dietary supplements of this kind, are significantly less absorbed as they are simply too large to efficiently travel to the soft tissues of the joints. Therefore, the manufacturer decided to create a product with isolates (small molecules) instead of loading it with thousands of milligrams of glucosamine and chondroitin. Thus, Cortaflex was born – a unique formulation of building blocks (isolates) of glutamine, glutamic acid, glucuronic acid, glycine, proline, supplemented with organic sulfur (MSM) to aid easier absorption into the body, and plant-derived hyaluronic acid (in some products, hyaluronic acid booster).

Only pharmaceutical-grade ingredients are used, ensuring that you are giving your pet a safe, natural, and high-quality product.

Hialuronska kislina je osnovna sestavina mazila v sklepih oz. sklepne tekočine sesalcev, ki obnavlja visokoelastične lastnosti sklepne tekočine in izboljša gibljivost sklepov. Ker je vsrkanje hialuronske kisline živalskega izvora zaradi njene visoke molekulske teže ob zaužitju slabo, v Cortaflex za pse in mačke uporabljamo hialuronsko kislino rastlinskega izvora. Njena bistveno nižja molekulska teža omogoča boljšo absorpcijo.

Cortaflex is a dietary supplement for joint health and is not a medication. You can feed your pet Cortaflex indefinitely with the prescribed daily dosage. If your dog or horse regularly receives Cortaflex, their joints will be better able to handle daily stresses. Breed characteristics and rapid growth can further accelerate joint wear and injury. Therefore, we recommend daily supplementation with Cortaflex for young animals of breeds more prone to joint issues.

Cortaflex is safe for dogs and cats of all ages and physical conditions. It’s a supplement for natural joint health, and Cortaflex is definitely the best choice for your puppy’s joint health needs.


Yes, there are fundamental differences in the formulation of Cortaflex for dogs, horses, or humans. Horses require different nutrients than dogs or humans. For example, Cortaflex for horses contains copper, a trace metal in amounts beneficial to horses but not recommended for dogs. In addition to the specific combination of nutrients, each version of Cortaflex is also made to be palatable to its intended consumer. Cortaflex for humans comes in capsule form, Cortaflex for dogs is flavored with beef and liver, while Cortaflex for horses has a lucerne flavor.
