True for some horses. Untrue for others. Some horses (even with all the training and work) put selves in constant stress that may cause ulcers etc. Supplements just take the edge off for such animals.
P.S. I'm not talking about my own mares because they don't need a calmer. But I know some (mostly higher level show horses) that need it.
