The is hands down the best price for a HA supplement. Most supplements have 100mg HA per 2 oz where the Flex Force is per 1 oz. My gelding has a bog spavin which was reduced by half of its size in 3 weeks after starting the HA supplement. My 16 y/o OTTB goes wonderfully on it AND even though she is extremely picky, she licks her tub clean every time.
