Gelding is a little stiff, I usually use SmartFlex but this is on sale so I'll try it.

Best joint supplement on the market. We have a 22yr old Quarter Horse who had joint issues and was sore for him to move around. Now he is in Western and English horse shows almost every weekend and if not showing is out pleasure riding 6-10 miles per day and most of it in a trot or canter. Love this stuff.

Best Answer: The Rapid Flex is a blend of a variety of natural herbs used for inflammation which is the cause of pain. Devils Claw is a single ingredient and may not be enough depending on the horse's issue. Easy Willow is the base ingredient of aspirin and should not be used long term due to effects on the overall health as well as stomach issues. Longer than 2 or 3 weeks is long term. It can be more effective in the short term. I have used Rapid Flex and Easy Willow with good results but for different purposes. I now supplement daily with tumeric (non-irradiated) for overall inflammation since the main purpose has resolved/healed.
