The best results have been observed when it has been used in conjunction with GrazeEzy along with our other recommended diet adjustments.
While you are building up GrazeEzy, feed SOS high dose to overcome more serious issues. Once the horse is back to normal, gradually drop the amount. Keep some on hand for adding when necessary.
For acute problems remove the horse from ALL green, grass until he is back to normal, then gradually and carefully reintroduce grass again.
