I just read an article in a magazine that detailed a research done on joint supplements that's been published in a Veterinary Journal where two groups of horses with the same levels of arthritis were put through a regime of daily exercise on a treadmill over a period of time to measure the length of stride to see if they improved after one group was put on a course of supplements and the other on a placebo. Both groups were treated the same in terms of stabling and turnout
All of the horses became more flexible and increased their length of stride - the horses on the supplement were no better than the ones on the placebo
THIS. Glucosamine and HA are both unable to be absorbed by the horse's gut. It's science. The molecules are simply too large and complex. As well, a majority of glucosamine is produced from shark fins and is a global problem leading to the decline of a very important species. So when you buy glucosamine, you are supporting these abusive practices :(
MSM can be absorbed but, as above, it's effectiveness can be debated for an already arthritic horse.
The best thing you can do is talk to your vet and make as many positive management changes as are possible including increased turnout, consistent moderate physical activity (ie light rides every day), long warm up and cool down periods, icing the legs after exercise and using NSAIDs after tough rides.
After that, the use of legend, Adequan, glucosamine IM, Map5, Icon, Pentosan, etc.. can also work to manage the arthritis. Posted via Mobile Device
