Product Description:


FlexAbility+ PLUS is one of the highest specification joint supplements available in the UK and now in the US. FlexAbility Plus has two clinical and scientific studies demonstrating the positive effects of joint supplementation, and is the only joint supplement in the UK with a published, peer reviewed paper in The Journal of Equine Veterinary Science. The study is the largest undertaken in recent history and the findings were also accepted and presented at the British Equine Veterinary Association Congress. The clinical trials showed reduction in lameness scores, increased range of motion, increased muscle tone, increased ease of movement, and increased joint flexion. 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 including marine DHA & EPA, Hyaluronic Acid (HA), and bioavailable Vitamin C. With low dust, high palatability, clinical trials, significant results, 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. See below for the science behind each active ingredient.


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. FlexAbility+ PLUS helps to promote and maintain normal mobility and joint function for all horses and ponies and provides nutrient support for joints against the rigors of training and competition. It can also help to maintain normal mobility and joint function in older animals


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. FlexAbility Plus is suitable for all horses and ponies in training and competition to provide nutrient support for joints, to help to maintain normal mobility and joint function in older animals, and for use in young animals to support normal joint health, development, and mobility. Feed at loading rate for 14 days then reduce to the maintenance rate. Effects can be seen in as little as 7 days, but normally by 10-14 days. What to expect: freer movement, longer stride, less stiffness, increased rolling, more athleticism

The science behind each active ingredient. 

We believe that when comparing joint supplements, the key elements to consider are:

  • The actual level of active ingredients as declared by the manufacturer
  • The rate at which each manufacturer is advising you to feed (This needs to be sufficient to provide the correct level for a horse - not a smaller animal)
  • The quality and bioavailability of the ingredients used (Are they an approved and certified manufacturer? When my horse eats this, will it actually be in a digestible and useable form?)
  • Do they have any published or clinical data to support their claims?

Chondroitin is a natural component of Aggrecan (a proteoglycan – a protein combined with carbohydrates), a large molecule found in cartilage. Chondroitin has been extensively studied and 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.

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 cheaper plant source.

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 Methyl-Sulfonyl-Methane 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 and repair of many structural tissues within the body like skin, hoof and cartilage. Secondly, MSM itself has anti-inflammatory properties, which is why we include MSM to aid in joint comfort and encourage joint health.

Vitamin C (Ascorbyl monophosphate) A natural water-soluble anti-oxidant which under normal situations is made by the horse in the liver. During certain times when 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 L-Ascorbic acid, unlike the human. When supplementing vitamin C to horses it is important to use a form which can be absorbed efficiently, which is why we only use the more bioavailable and stable for of Vitamin C Ascorbyl monophosphate.
