In just the past three weeks I have received a number of calls and messages regarding how well MellowMax has done to relieve horses with ulcer related problems. I believe this is happening for two reasons; First, it helps to calm a horse down without using herbal or chemical tranquillizers. Second, the added magnesium works as a great acid buffer. While supplementing is important, keeping some kind of long hay (preferably mature) in front of them throughout the day is very important. If you have any questions about your horse regarding these issues please feel free to give us a call. 800-580-6632
