Horse Joint Supplements in Australia
An independent comparison of the most popular equine joint supplements by ingredients, clinical evidence, and daily cost.
Arthritis and joint degeneration affect an estimated 60% of horses over the age of 15. With dozens of joint supplements on the Australian market, choosing the right one can be overwhelming. This guide compares the leading options based on what matters most: active ingredients, published clinical evidence, ease of use, and cost.
This comparison was compiled by Dr John Stewart (BVSc Honours, MRCVS) with decades of equine veterinary experience. While we manufacture Joint Rejuvenate, we've included it alongside competitors to give horse owners an honest, side-by-side view.

Why Green-Lipped Mussel Stands Out for Horses
Most joint supplements target only one or two aspects of joint health — glucosamine for cartilage, or omega-3s for inflammation. Green-lipped mussel (Perna canaliculus) is unique because it naturally contains all five key joint-supporting compounds in a single whole-food source.
The landmark Cayzer et al. (2012) study — a randomised, double-blind, placebo-controlled trial published in the Equine Veterinary Journal — demonstrated significant improvement in horses with chronic fetlock lameness when treated with green-lipped mussel extract. This is the gold standard of veterinary evidence.
For horse owners, the practical advantages are also significant: Joint Rejuvenate is a simple powder mixed into hard feed, with no vet visits required for administration. It's compatible with other treatments including pentosan polysulphate injections and NSAIDs like phenylbutazone.
