Joint issues are common in horses, with Osteoarthritis contributing to 60% of lameness issues. When pressure is placed upon joints during exercise, an inflammatory response is triggered to protect the joint from trauma.

Breaking this cycle is key to managing a horse’s comfort and longevity through promoting a healthy joint environment. Feeding joint nutraceuticals support healthy joint structures leading to improved comfort, consistent performance, and a reduction in lameness.

Best-Flex HA® is the highest specification joint supplement on the market containing the highest levels of proven joint supporting nutrients Glucosamine HCl, Chondroitin Sulphate, MSM and Hyaluronic Acid. Best-Flex HA® also contains Boswellia to help soothe active or tired horse joints, Omega-3 fatty acids to maintain supple horse joints and the antioxidant Vitamin C that helps to neutralise free radicals. Best-Flex HA is suitable for all horses, especially performance horses and horses suffering with joint or mobility challenges.
