SmartEquine Smart & Simple Magnesium Oxide is a single-ingredient magnesium supplement. Magnesium is a cofactor in hundreds of metabolic processes and matters most for muscle and nerve function — which is why it turns up in both calming and metabolic feeding programs.
Feeding it on its own is the economical way to add magnesium to a ration that’s otherwise balanced, without paying for a full calming blend or doubling up on ingredients your horse already gets.
