We had exactly the same issues and tried lots of equine joint supplements before we triednaf superflex and it really sorted my mare out. Three months on and she's a different horse..Sorry to hijack an old post but this struck a chord..
Ressurecting an old tread but I've been trying superflex for two week and she's really come on. I'm using this liquid version http://www.naf-equine.eu/uk//products/productDetail.jsp?detail_id=superflex-liquid - is this better than the powder?
Does anyone use NAF Superflex for their horse? My friend has recommended it but looking for other opinions? Its this..http://www.naf-equine.eu/uk//products/productDetail.jsp?detail_id=superflex
