Horses with Increased Magnesium Needs

Horses that perform heavy work, sweat frequently, are pregnant, or nursing a foal often require more magnesium. Additionally, horses that are naturally nervous or excitable typically have higher magnesium needs.

A Versatile Mineral

Magnesium is essential for around 300 bodily processes. This mineral is crucial for the health of your horse’s bones, muscles, and nervous system. It also plays a role in energy production and metabolism. Magnesium positively affects focus and mood as well. In short, a horse with sufficient magnesium intake can concentrate better, has supple muscles, plenty of energy, and recovers quickly after training.

Magnesium for Stress Relief

Magnesium plays a key role in a horse’s nervous system. Scientific studies have shown that magnesium helps regulate signal transmission between nerve cells, ensuring effective communication within the nervous system. Improved signal transmission contributes to a calm and balanced state of mind. Therefore, magnesium is especially beneficial for nervous or stressed horses. A stressed or anxious horse also uses more magnesium than a naturally calm one.
Magnesium isn’t just vital for the nervous system. A well-absorbed magnesium supplement can help reduce muscle cramps and stiffness while promoting overall flexibility. This is particularly important for sport horses that perform intense physical activity.

Do Horses Need Extra Magnesium?

Magnesium is present in forage, but some horses may require additional amounts. In certain situations, a supplement can be beneficial. It’s also worth noting that forage in the Netherlands often has low magnesium levels, especially if it comes from nutrient-poor sandy soils. While not all horses suffer from magnesium deficiency, it is a common issue, particularly in sick or stressed horses and sport horses.

Supplementing Magnesium

Horses under significant stress or those exerting themselves heavily may benefit from a magnesium supplement. It’s also important to consider how much calcium they consume, for instance, through feeds like alfalfa. Calcium can inhibit the absorption of magnesium, meaning a calcium-rich diet could contribute to magnesium deficiency in your horse.
If you suspect a magnesium deficiency, you can try supplementing magnesium for a period to see if your horse shows improvement. Any excess magnesium will simply be excreted in the urine. It’s crucial to provide magnesium in a highly absorbable form, such as liquid magnesium chelate.

The nervous system and immune system also need magnesium. The amount of magnesium a horse needs depends on factors such as the horse's age and the amount of work the animal does. For example, a sport horse needs more magnesium than a recreational horse, and a mare with a foal at foot needs more than an adult gelding.
