Why Choose Forageplus Ultra-Pure Magnesium Oxide for Horses?
Magnesium is an essential mineral in your horse’s diet, needed for normal nerve and muscle function, bone and hoof structure, and energy metabolism. Forageplus Ultra-Pure Magnesium Oxide for Horses is 99.8% pure and supplies 60.7% elemental magnesium, so a small daily amount goes a long way. It is suitable for feeding to laminitis-prone horses.
Our magnesium oxide for horses is ultra-low in iron with just 26ppm (0.0026%), which is 20 times lower than the commonly available magnesium carbonate form. Many forages are already high in iron, so a magnesium source that adds as little iron as possible helps keep the whole diet in balance.
Key Benefits:
- Ultra-low iron content: At just 26ppm, our magnesium oxide contains significantly lower iron than other magnesium sources like magnesium carbonate (which can contain up to 500ppm of iron).
- High purity: 99.8% magnesium oxide, so you know exactly what you are feeding.
- Muscle and nerve function: Magnesium is needed for normal nerve and muscle function.
- Hoof and bone structure: Magnesium is one of the minerals needed for normal hoof and bone development.
- Energy metabolism: Magnesium is involved in a wide range of enzyme reactions, including those that release energy from feed.

What is Magnesium for Horses?
Magnesium is an essential mineral that plays a key role in several physiological processes, including muscle contraction, nerve transmission, bone formation and energy metabolism.
Many horses’ diets fall short of magnesium, particularly where the forage itself is low in magnesium. A forage analysis shows exactly where your horse’s diet stands, and Forageplus Ultra-Pure Magnesium Oxide provides a concentrated, low-iron source to close the gap.
How Much Magnesium Should I Feed My Horse?
Supplementation needs depend on factors like your horse’s activity level, age, and overall diet. For an average 500kg horse, we recommend 1 x 25ml scoop per day (approx. 23g, providing 13.8g of elemental magnesium), unless otherwise indicated by a forage analysis.
- Pregnant, lactating, young horses, and those in moderate to heavy work will need higher amounts of magnesium.

Learn about how to tell if the magnesium you are buying is of high purity and low in iron here.
We do not stock magnesium chloride because it is less palatable and you would have to feed 5 times more chloride than oxide to get the same elemental magnesium supplementation.
We carefully select only the finest magnesium oxide products, as your horse’s health is our top priority. The magnesium oxide we sell separately and use in our balancers is of human pharmaceutical grade, selected for the highest purity.
Every Batch Tested Before Release
We go beyond manufacturing accreditation by independently assessing every batch before sale for purity, safety and consistency. Our quality assurance programme includes contaminant screening, batch traceability and rigorous quality control.
Forageplus does not advise the feeding of separate minerals unless levels have been checked by carrying out a forage analysis. The ratios of minerals are important and feeding one mineral without supplementing correct levels of another can be detrimental to horse health. If you are uncertain of mineral levels then feeding either a Forageplus Equine Balancer or carrying out analysis of forage is wise.
