Magnesium for Horses: Benefits and Supplementation
Magnesium is an essential mineral that plays a crucial role in the overall health and well-being of horses. From supporting muscle function to enhancing stress tolerance, magnesium is vital for various physiological processes. In this blog, we will explore the benefits of magnesium for horses and provide insights into effective supplementation strategies.
The Importance of Magnesium for Horses
Magnesium is involved in over 300 metabolic processes in the horse's body, making it indispensable for maintaining optimal health. Here are some key benefits of magnesium for horses:
1. Muscle Function and Relaxation
Magnesium works closely with calcium to regulate muscle contractions. When muscles contract, calcium is released onto muscle fibres. Magnesium then helps to push calcium back into storage, allowing muscles to relax. This process is essential for preventing muscle cramps, spasms, and pain, especially after intense exercise. This balance between magnesium and calcium is what keeps your horse's muscles functioning smoothly and efficiently.
2. Nervous System Support
Magnesium plays a critical role in nerve function by regulating ion balance across cell membranes. This helps nerve cells transmit signals efficiently, reducing the likelihood of nervousness, excitability, and anxiety in horses. A calm and focused horse is more likely to perform well in training and competition. Just like humans, horses benefit greatly from a balanced nervous system, ensuring they stay cool and collected under pressure.
3. Stress Tolerance and Recovery
Stress depletes magnesium levels in the body, making it essential to ensure adequate intake. Optimal magnesium levels can improve a horse's tolerance to stress and speed up recovery after exposure to stressors. This is particularly important for horses that undergo frequent training or competition. Think of magnesium as a stress shield, helping your horse bounce back faster and stay resilient.
4. Insulin Sensitivity and Metabolic Health
Magnesium helps cells respond to insulin, which is crucial for maintaining healthy blood sugar levels. Supplementation with magnesium can improve insulin sensitivity, particularly in overweight horses, and may help prevent conditions like laminitis. By supporting metabolic health, magnesium ensures your horse stays fit and healthy, avoiding the pitfalls of metabolic disorders.
5. Bone Health
Magnesium aids in the absorption of calcium from the diet, supporting healthy bone development and maintenance. This is especially important for growing horses and those with high physical demands. Strong bones are the foundation of a strong horse, and magnesium plays a key role in building and maintaining this foundation.
Signs of Magnesium Deficiency
While severe magnesium deficiency is rare, mild to moderate deficiency can occur and affect a horse's mood and performance. Common signs of magnesium deficiency include:
- Nervousness and anxiety
- Muscle tremors and cramps
- Hypersensitivity to sound and movement
- Irritability and resistance to training
- Fatigue and irregular heartbeat
Factors Leading to Magnesium Deficiency
Several factors can contribute to magnesium deficiency in horses:
Diet Composition
Fast-growing grasses, often low in magnesium, can lead to deficiency, especially in the spring. High-fibre, oxalate, phosphate, and fat content in forage can also reduce magnesium absorption. Ensuring your horse's diet is balanced and contains enough magnesium-rich foods is crucial to prevent deficiency.
Soil Quality
Forage grown on acidic or clay soils may have lower magnesium levels throughout the year. Understanding the soil composition of your grazing fields can help you anticipate and manage potential deficiencies in your horse's diet.
Exercise
Horses that exercise frequently lose magnesium through sweat, increasing their dietary needs. Active horses, especially those in regular training or competition, may require additional magnesium to replace what is lost during intense physical activity.
Supplementation Strategies
To ensure your horse receives adequate magnesium, consider the following supplementation strategies:
Dietary Analysis
Before adding supplements, analyse your horse's diet to determine existing magnesium levels. This can help you make informed decisions about supplementation needs. A thorough dietary analysis can reveal gaps in nutrition and help you address them effectively.
Magnesium Sources
Magnesium can be supplemented in various forms, including:
- Magnesium Oxide: Highly absorbable and cost-effective, making it a popular choice for supplementation.
- Magnesium Citrate and Sulphate: These forms are also effective but may require larger doses to achieve the same effect as magnesium oxide.
Dosage Recommendations
The National Research Council (NRC) recommends a daily magnesium intake of 15 mg per kg of body weight for horses. For a 500 kg horse, this equates to 7.5 g per day. Horses undergoing moderate to intense exercise may require up to 15 g per day to compensate for losses through sweat. Always consult with a veterinarian or equine nutritionist to determine the appropriate dosage for your horse.
Feeding Practices
To improve palatability and minimize digestive upsets, divide the daily magnesium dosage into two meals. Gradually increase the dose to ensure your horse adjusts to the supplement. Introducing supplements slowly helps prevent any adverse reactions and ensures your horse receives the full benefit.
Conclusion
Magnesium is a vital mineral for maintaining the health and performance of horses. By understanding its benefits and implementing effective supplementation strategies, you can ensure your horse remains healthy, calm, and resilient. Always consult with a qualified equine nutritionist to tailor supplementation to your horse's specific needs.

Remember, keeping your horse's magnesium levels in check is a simple yet powerful way to ensure they stay happy, healthy, and performing at their best. Don't let magnesium deficiency hold your horse back—make sure they're getting the nutrients they need to thrive.
How do I know if my horse needs magnesium?
Signs of magnesium deficiency in horses include nervousness, anxiety, muscle tremors, cramps, hypersensitivity to sound and movement, irritability, resistance to training, fatigue, and irregular heartbeat. If you notice any of these symptoms, consider consulting with a veterinarian or equine nutritionist for proper diagnosis and advice on magnesium supplementation.
Can you give a horse too much magnesium?
Yes, it is possible to give a horse too much magnesium. Over-supplementation can lead to adverse effects such as diarrhea and imbalance of other essential minerals. Always follow dosage recommendations and consult with a qualified equine nutritionist or veterinarian to ensure safe and effective supplementation.
How long does magnesium take to work in horses?
The effects of magnesium supplementation can vary depending on the horse and the severity of deficiency. Generally, you may start to notice improvements in a few days to a few weeks. Consistent supplementation and monitoring will help ensure the best results for your horse's health and performance.
Which form of magnesium is best for horses?
Magnesium oxide is a popular choice for supplementation due to its high absorbability and cost-effectiveness. Other effective forms include magnesium citrate and magnesium sulphate, though they may require larger doses to achieve the same effect as magnesium oxide. Consult with an equine nutritionist to determine the best form and dosage for your horse's specific needs.
