Well I've been doing a little research and have found that there are a few products in the health food stores which contain the same ingredients and levels as the horse products and are also alot cheaper. Currently I have been feeding Advanced feeds "joint guard" which is $300 for a 4kg tub. I have found a product "Nazmy Naturals Glucosamine chondroitin Joint Formula with MSN" in the health food shop which is pretty much on par with joint guard however also contains "Chondroitin" which "joint guard" does not. Currently its on special for $70.95 (half price) for a 2kg tub. I'm thinking about buying some and giving it a go. Just wondering if anyone has used this before or has any information on it?
