At Performance Equine Nutrition, we often hear from owners dealing with behavior that may have more than one contributing cause. Jonie’s story stood out because the changes in her horse were severe and had become dangerous.

A Horse Who Had Become Unsafe
Jonie described a horse who had once been honest and dependable but had become unrideable. He was rearing, striking, difficult to handle, pacing his stall, and rarely appearing to rest. He had also been diagnosed with Grade 4 ulcers.
Behavior this severe requires careful veterinary attention and appropriate safety precautions. Pain, ulcers, diet, training history, medications, and other medical conditions can all affect behavior, so no single symptom or feeding detail can establish the cause.
Reviewing the Full Management Picture
The horse was eating a calcium-rich alfalfa diet and receiving omeprazole and gut-support products for his ulcers. Those details prompted a broader review of his ration and supplement program, including whether magnesium intake was appropriate for his individual needs.
MagRestore was added as one part of his management plan. It was not a replacement for ulcer treatment, veterinary care, or safe handling.
Jonie’s Six-Week Update
Six weeks later, Jonie reported a major improvement. The rearing and striking had stopped, the horse was resting more normally, and she felt safe and happy riding him again. In her words, he felt like a different horse.
This is one owner’s experience, not proof that every horse with dangerous behavior has a magnesium deficiency or will respond the same way. Because several parts of the horse’s care were being addressed, we cannot isolate one variable as the sole explanation. Still, the response suggested that magnesium support may have been a useful part of this horse’s individual program.
What Owners Can Take From This Story
When a horse’s behavior changes dramatically, start with safety and veterinary evaluation. Then review the complete picture: pain, digestive health, diet, workload, medications, environment, training, and mineral balance. Thoughtful nutritional support can be valuable, but it should sit alongside diagnosis and good horsemanship rather than replace them.
