"My horse has a bit of arthritis in his front ankle. After just 2 weeks with Mega Grand Flex I noticed he was feeling much better and not as stiff when I rode. This is the first supplement I have found that I really could see the results. My horse now has a spring in his step and ready to roll!"

"I started using Mega Grand Flex last month and my horse loves it! She is a picky eater and often leaves her supplements behind in the bottom of the feed dish. She licks her bowl clean with the Mega Grand Flex. I haven't been able to tell if she feels better ot not because it is too soon to tell. But I am confident this product will produce results."

"We chose the Mega Grand FLex for all the healthy ingrediants to transition from the HA Synergy. Our horse TJ had a previous injury and we want to allow him maintain good healthy joints for all the work he does. TJ has never refused his food with Mega Gran Flex and is moving greatly even with the cold weather."
