I have been using these SFM products for many many years now
I successfully used the whole programme to treat a new horse who suffered with ulcers, and the vets scoping proved it worked!
I have always fed the maintenance to all the horses I have owned, to prevent ulcers from forming
Any type of stress to the horse can cause ulcers, such as diet, travelling, exercise, being stabled away from home, a change in their daily routine,
a loss of a stable companion etc
I can highly recommend this supplement
