A lack of magnesium can make some horses harder to handle. Riders may respond by exercising them more in an attempt to manage the behavior, but that can increase stress and magnesium loss. The result may be a cycle of fatigue, muscle cramping, and a negative association with work or training.
Magnesium Support for Performance Horses
Supplements from Performance Equine Nutrition offer a targeted, flexible, and safe approach to addressing magnesium deficiency. MagRestore has been shown to alleviate symptoms of magnesium deficiency in horses. It may take up to four servings daily before symptoms begin to dissipate, with noticeable improvements typically seen within ten days.
After the initial symptoms improve, maintenance doses vary, but one to two servings daily are generally recommended. This flexibility allows owners to tailor supplementation to the individual horse’s needs.
Workload and Magnesium Needs
Performance horses can lose magnesium quickly during heavy training, travel, or competition. This can contribute to a deficiency when magnesium is used faster than it is replenished. Depending on exercise intensity, performance horses need 10 to 30% more magnesium than usual while they are working.
Proper magnesium levels are important for the health, comfort, and performance of horses, particularly those in competitive or high-stress environments.
Using MagRestore
MagRestore is given orally and is available in pellets or powder. For horses showing more severe signs of deficiency or those in heavy training, MagRestore can be combined with a magnesium bath for additional support. Horses in demanding work often require a higher daily dosage, sometimes double the amount used for a non-working horse.
We recommend splitting magnesium supplementation between morning and evening feedings to support absorption and minimize potential laxative effects.
