Magnesium is an incredibly important mineral for horses. It is important for muscles, bones and the nervous system. Often owners notice magnesium deficiency quite late. While a magnesium deficiency is quite common and can have a significant impact on horses' mood and performance.
How do you know if your horse is magnesium deficient? And what can you do about it?
Signs of magnesium deficiency
Sometimes the symptoms of magnesium deficiency fall somewhat into the category of 'vague complaints'. They usually only show up when your horse has been deficient in magnesium for a while. It is therefore easy to overlook a shortage. Signs of a magnesium deficiency include:- Fatigue, poor sleep
- Stress, nervousness
- Muscle cramps or muscle tremors
- Hard muscles, muscle pain
- Difficulty concentrating, very distracted in riding
- Difficult cantering or cantering at will
- Injury prone
- Demineralisation of bones
- Insulin resistance, EMS
- Lameness
Why do horses get magnesium deficiency?
Some horses have a higher magnesium requirement than others. They need to get magnesium through their diet. Much of our Dutch roughage is very poor in magnesium because the soils are quite acidic. Consequently, very little magnesium gets into the grass. Horses that sweat a lot, work a lot, are pregnant or nursing a foal need more magnesium. Horses that are naturally very nervous or hot also often have a higher magnesium requirement. The roughage usually does not supplement the required magnesium sufficiently and concentrate often does not contain enough absorbable magnesium either. A mineral balancer is usually better, but may still be insufficient for sport horses. In that case, a magnesium supplement is needed.What does magnesium do?
