Absolutely love V-Flex! I know my horse is getting all the support he needs from ingredients that are species appropriate. Highly recommend

Have used Best Flex on my 22 year old TB ex-racehorse for several years.  He looks brilliant (though I say it myself!), and he also gets Muscle Treats instead of ordinary sweeties.  I've now put him on the new Benevit without iron, just to make sure he has everything he needs.

I started feeding V-Flex a couple months ago and it has changed my horses way of going! Loves the taste and enjoys his food!

Cannot comment as could not cancel order once placed so will not use for another 12 months

Nutrition Information

 V-Flex® is  the only joint supplement supplying high levels of joint supporting nutrients in a vegetarian formulation, allowing you to keep your horse a herbivore! The feeding of joint nutraceuticals is now a well-accepted management tool for keeping horses moving freely and performing at their best, with published research supporting the benefits of feeding Glucosamine hydrochloride (HCl), Chondroitin sulphate, Hyaluronic acid (HA) and Methyl sulphonyl methane (MSM). However, Chondroitin sulphate can only be sourced from animal tissues, so Feedmark have developed Chondroitex®, a plant-based alternative to Chondroitin, and have given you the opportunity to feed your horse like nature intended. 

Chondroitex® provides a combination of ingredients beneficial to joint health, including high levels of the algae-sourced Omega-3 Docosahexaenoic acid (DHA). DHA is a vital component of the body's response to damage as it is the precursor of cells and compounds known as pro-resolving mediators that help restore tissues. Providing a dietary source of DHA ensures utilisation by the body, and when combined with Hyaluronic acid, provides optimum support to the horse's joint tissues.

The support provided by Chondroitex®, Glucosamine HCl, Hyaluronic acid and MSM is further enhanced by Boswellia and Vitamin C. Boswellia is well known for its medicinal properties that complement the actions of DHA and support mobility, whilst Vitamin C is an antioxidant that neutralises damaging free radicals.

V-Flex® can be fed to all horses and ponies and is safe to feed long-term.

Feeding Guide


Body weight  Amount per day
Up to 250kg 1 scoop
250kg - 400kg 2 scoops
400kg - 600kg 3 scoops
Over 600kg 4 scoops

1 level (50ml) scoop of V-Flex® weighs approximately 33g.

Feed the recommended level, or as recommended by your veterinary surgeon. The daily feeding rate can be adjusted based on your horse’s work load, age and mobility, to suit their long term daily requirements. Before and during a period of hard exercise, the daily levels can be increased to the next scoop level to provide extra joint support and may be continued on a long term basis for superior joint health support.

Feed supplements should be fed according to body weight. Introduce to the horse's diet gradually, splitting between feeds (when applicable).
