What Causes Anxiety & Nervous Behaviour in Horses?
Veterinarians define anxiety in horses as an exaggerated stress response, often shaped by genetics, diet, environment, or training routines.
Horses can become reactive in high-pressure settings like shows, travel, or when faced with sudden changes in their surroundings.
Deficiencies in nutrients such as magnesium, irregular schedules, or limited coping outlets can all make things worse. The best solutions combine consistent management, supportive nutrition, and well-chosen calming supplements, which are part of our broader horse supplement collection.
How Calming Supplements Can Help
A study in the Journal of Equine Veterinary Science (2015) showed that when Standardbred geldings were given magnesium aspartate, they reacted more slowly to sudden startles. Horses on the higher dose took longer to cover a short distance after being startled, which pointed to a calming effect.
A review in Veterinary Clinics of North America: Equine Practice (2011) explained that when horses don’t get enough magnesium, they can become nervous, excitable, and handle stress poorly. Bringing magnesium levels back to normal can help them stay calmer and support healthy nervous-system function.
So, therefore there are two things to keep in mind when using calming supplements:
- Magnesium (especially aspartate form) shows to affect reaction speed under stress in horses.
- Proper dosage & administration studies point to measurable effects when supplementing beyond base dietary magnesium levels.
Choosing the Right Calming Supplement
Picking the right calming supplement depends on your horse’s age, workload, and natural temperament.
Consider whether your horse needs daily support, quick-acting help, or a product gentle enough for sensitive types. The form matters too; powders, pellets, or liquids. Safety for long-term use should always guide your choice. Below we have a few recommendations:
- Performance / High-Stress Horses → fast-acting powders or liquids
- Everyday / Maintenance Horses → safe, gentle daily formulas
- Sensitive or Nervous Horses → blends with proven calming actives
