Customer Reviews

  1. Been using for my boy who has arthritis in hocks and flat stifles. Both legs have been medicated but when we moved from 24/7 turnout to only daytime during the winter months, I started to use this supplement. WOW – what a difference!! He’ll now be on this throughout the year; he is springy and bouncy and feeling fantastic (a huge change from last winter). Really impressed and highly recommend.


  2. I’ve had my horse, who has had his stifles pinned due to bone cysts, on Performance Flex for around 6 months now. Wouldn’t use any other product! Within a week or so, I saw an improvement in his movement and way of going, and he seems so much more willing and keen to work and generally happier in himself. I use it with Premier Calm for a powerhouse combo!
