I have been using Omega Horseshine for more than 8 months now (just finished my first 50 lb bag and already received my second 50 lb bag). I started giving it to my insulin-resistant horse and liked it so well that I put my other 4 horses on it a few months ago. My farrier cannot get over how good all of my horses feet are doing (all barefoot), especially the IR mare who has suffered 3 episodes of laminitis in the past. The IR mare was still recuperating last summer but she was able to walk on gravel for the first time since I bought her (2004).
