My 23 yr old gelding has DSLD. He has been on Flex-Force MSM and I add full strength Flex-Force Glucosomine and blend together. He has no lamness. My 10 yr old dogs both have hip issues and have been on this for years. Both run like puppies.
I use this MSM daily in combination with pure glucosamine on my Thoroughbred. He has bone chips in his knees from racing and I give him this combo proactively for the inevitable arthritis is he sure to have. He has stayed very sound for the 8 years I have had him. He's 16 and moves like he did 8 years ago. A very cosr effective way to get a joint supplement into him daily!
