Science Supplements® FlexAbility Professional Horse Joint Support is most likely the highest specification joint supplement available in the UK and now in the US. A unique combination and optimum levels of scientifically proven ingredients includes glucosamine, chondroitin sulfate, MSM, marine DHA & EPA (omega 3), vitamin C (ascorbyl monophosphate), boswellia, hyaluronic acid (HA), Green Lipped Mussel, rosehip and collagen peptides. Results may be seen in as little as 14 days.

FlexAbility Professional is a nutritionally advanced formula of FlexAbility Plus, the only joint supplement on the market with two clinical and scientific studies demonstrating the positive effects of joint supplementation and the only joint supplement in the UK with a published, peer reviewed paper in The Journal of Equine Veterinary Science showing FlexAbility aids in maintaining normal joint function and mobility.

FlexAbility Professional is designed for those horses needing the absolute maximum levels of joint support, such as those competing at the highest levels of competition and undergoing the greatest stress to joints, tendons, and ligaments. We provide declared levels of key nutrients involved in cartilage synthesis and support using a unique combination and optimal levels of scientifically proven ingredients, including glucosamine, low molecular weight chondroitin, MSM, omega 3 fatty acids DHA & EPA, hyaluronic acid (HA), boswellia, collagen peptides, rosehip and vitamin C. With low dust, high palatability, quality ingredients, effective levels and manufactured under the strictest conditions in our approved and certified UFAS and BETA NOPS-approved manufacturing facility, you can be confident that this product actually provides results—not just promises. 

Note: Data is correct as of November 2019 and compares some of the leading joint supplements in the UK and US based on their published maintenance feeding rates for an average 1100lb horse and published declared levels of active ingredients. This is only one method of comparison and should be used as a guide.

Wear and tear on the skeletal system, particularly the joints, occurs both as the result of exercise training and simply as part of the aging process. A key factor in maintaining joint health and function is an adequate supply of the nutritional building blocks needed to support cartilage turnover and joint lubrication. Further, with excessive or prolonged stress to the joints, additional support is needed to maintain joint tissue integrity and reduce inflammation. FlexAbility Professional provides declared levels of ingredients meant for the particular strain undergone by performance horses, for horses with known joint damage, and for older horses with arthritic changes.

Joint damage is much easier to prevent than to treat. Cartilage in particular has limited capacity to heal, so the best time to supplement joint health is before damage has occurred. Once damage has occurred, your horse needs higher levels of nutrient support and additional components to protect the joints from further damage and reduce inflammation that leads to pain. FlexAbility Professional is suited for horses in high levels of work or performance, for horses with known joint damage that would benefit from additional support, and for older horses with arthritic changes.


The Science behind Each Active Ingredient

Chondroitin is a natural component of Aggrecan (a proteoglycan, protein combined with carbohydrates), a large molecule found in cartilage. Chondroitin has been extensively studied, and has been found to have a synergistic effect when used in combination with glucosamine. Both glucosamine and chondroitin act as building blocks for repair, but also have their own anti-inflammatory properties. Together they counteract inflammation by inhibiting the synthesis of Nitric Oxide Synthase (NOS) and Prostaglandin E2 (PGE2). Chondroitin supplementation has been evaluated in horses in combination with glucosamine and other ingredients.

Glucosamine is an essential building block for proteoglycans which make up the non-structural component of cartilage. Glucosamine has been recognized as a beneficial nutraceutical for joint health in both horses and humans for many years. It has been shown to reduce inflammation and cartilage turnover. Glucosamine and chondroitin work synergistically to reduce inflammatory mediators in the joint as well as improving repair.

Boswellia Serrata is an established nutraceutical in the human market, predominantly used for its anti-inflammatory effects in arthritis. Boswellia serrata contains boswellic acids, which work in many different inflammatory pathways, including the Arachidonic inflammatory pathway.

Collagen Peptides is a key component of every structural tissue in the body from bone to tendon to skin. Collagen makes up the scaffold of joint cartilage and is essential for its overall integrity. Oral supplementation with predominantly Type I bioactive collagen peptides in horses has been shown to reduce the signs of lameness over a 6 week period.

DHA & EPA are specific types of Omega 3 fatty acids which are only found in substantial amounts in omega 3 from marine sources. DHA and EPA have been found to be beneficial to many body systems in the horse including joints, blood, skin, and lungs. It is important to note that omega 3 from plant sources does not result in increased DHA and EPA in body tissues in horses, which is why we use a unique encapsulated marine DHA and EPA and not a cheap plant source.

Green Lipped Mussel Extract (GLME) has become popular in recent years following work performed in dogs and cats. Since then, GLME has been trialed in horses and has been shown to be beneficial in cases of arthritis. GLME contains a combination of marine omega 3 fatty acids.

Hyaluronic acid is an essential component of both synovial fluid and proteoglycans. It has been studied in horses both as an oral nutraceutical, but also in injectable forms for use straight into joints or into the vein. Hyaluronic acid shows to improve the visual swelling seen with joint disease and for use as an oral supplement in isolation. Daily servings upwards of 100 mg should be used.

MSM is a natural ingredient used in many supplements because it has two very important properties. Firstly, MSM is a source of sulfur. Sulfur is essential for the maintenance of repair of many structural tissues within the body like skin, hoof and cartilage. Secondly, MSM itself has anti-inflammatory properties that aid joint comfort and health.


Rosehip (Rosa canina) is commonly found in British hedgerows. Rosehips are known for the beneficial effects for managing arthritic pain. Rose hips are packed full of plant based antioxidants, including flavonoids and carotenoids.

Vitamin C (Ascorbyl monophosphate) is a natural water-soluble antioxidant which under normal situations is made by the horse in the liver. During certain times, excessive amounts of vitamin C are used, and the liver cannot keep up with the demand. Horses in work and older horses all have increased demand for vitamin C, and studies show that blood and tissue levels are often low in these groups of animals.

Vitamin C has been shown to be able to pass from the blood into joint fluid of horses, which allows it to neutralize damaging free radicals that have been produced as a result of excessive wear and tear. As the horse can produce its own vitamin C, its gut did not adapt for efficient absorption of the vitamin as it occurs naturally in fruit and vegetables in the form of
