Horse owners constantly seek effective, natural solutions to help manage anxiety and promote calmness in their equine partners, especially during stressful situations like competitions, travel, or training. Vitamin B1 (thiamine), magnesium, and ashwagandha are popular supplements known for their calming properties.
Vitamin B1 (Thiamine): The Nerve Soother
What is Vitamin B1? Vitamin B1, or thiamine, is a water-soluble vitamin essential for nerve function and energy metabolism. It’s commonly included in calming supplements to support the nervous system.
Benefits for Horses
- Nervous System Support: Thiamine promotes healthy nerve function, potentially reducing irritability.
- Stress Management: It may help horses cope with stressful environments like shows or transport.
Effectiveness
Thiamine is most effective for horses with deficiencies, often caused by high-grain diets or poor-quality forage, which can manifest as nervousness or poor coordination. Typical doses range from 500-1,000 mg/day for a 500 kg horse, with effects taking days to weeks. Research suggests high doses (2.2 mg per kg of body weight) can restore vigor in performance horses.
Considerations
- Deficiency Focus: Thiamine is most beneficial when addressing deficiencies, often linked to poor-quality diets.
- Gradual Effects: As a water-soluble vitamin, it’s safe but not an immediate calming solution.
- Synergistic Use: Thiamine is often paired with magnesium or other supplements for enhanced effects.
Magnesium: The Mineral for Muscle and Mind
What is Magnesium?
Magnesium is a critical mineral for muscle relaxation, nerve function, and metabolic health. It’s a cornerstone of many equine calming supplements due to its role in reducing tension, fizz and nervousness.
Benefits for Horses
- Muscle Relaxation: Magnesium helps prevent cramps and tightness, contributing to a calmer disposition.
- Reduces Hyperactivity: It supports nerve function, helping horses stay composed under stress.
- Versatile Use: Beneficial for horses in high-stress settings or prone to tying-up (exertional rhabdomyolysis).
Effectiveness
Research supports magnesium’s ability to reduce stress responses in horses, particularly those with low magnesium levels due to poor soil or forage quality. Magnesium is well-studied for its calming effects, particularly in horses with deficiencies due to poor absorption from feedstuffs or low soil quality. Effective doses range from 5-10 g/day for a 500 kg horse, with bioavailable forms like magnesium oxide, proteinate aspartate or citrate being most effective.
Considerations
- Bioavailability Matters: Forms like magnesium citrate or proteinate are more absorbable than magnesium oxide.
- Calcium Balance: Magnesium works with calcium, so ensure a balanced diet to avoid imbalances.
- Veterinary Guidance: Excessive magnesium can cause diarrhea, so consult a vet for proper dosing.
Ashwagandha: The Adaptogenic Herb
What is Ashwagandha?
Ashwagandha (Withania somnifera) is an adaptogenic herb used in traditional medicine to combat stress and promote balance. While less common in equine supplements than tryptophan or magnesium, it’s gaining popularity for its calming potential.
Benefits for Horses
- Stress Adaptation: As an adaptogen, ashwagandha may help horses manage stress by regulating cortisol levels.
- Promotes Calmness: It may reduce anxiety without causing drowsiness, making it ideal for performance horses.
- Holistic Support: Ashwagandha supports overall well-being, potentially boosting immunity and resilience.
Effectiveness
Limited equine-specific research exists, but anecdotal evidence and studies in other species suggest ashwagandha can reduce stress and improve behavior. Typical doses for horses range from 5-10 grams of root powder per day for a 500 kg horse, though standardized extracts may require lower doses.
Considerations
- Limited Research: Ashwaghanda's use in horses is less studied, so results may vary.
- Quality Matters: Choose high-quality, equine-specific ashwagandha products to ensure safety and efficacy.
Tyrosine: The Focus-Enhancing Amino Acid
What is Tyrosine?
Tyrosine is an amino acid that serves as a precursor to dopamine and norepinephrine, neurotransmitters linked to focus and stress response. It’s less common in equine calming supplements but may support mental clarity.
Benefits for Horses
- Improves Focus: Tyrosine may enhance cognitive function, helping horses stay alert yet calm under pressure.
- Stress Resilience: Supports neurotransmitter production, potentially aiding stress response.
- Performance Support: May benefit horses needing mental sharpness in competitive settings.
Equine research on tyrosine is limited, but it may help horses maintain focus during stressful events. Typical doses are not standardized but may range from 1-3 grams per 500 kg horse, based on human and small animal data. Effects vary by individual.
Considerations
- Limited Evidence: Tyrosine’s role in equine calming is speculative and requires further research.
- Potential overstimulation: Excessive tyrosine could increase alertness, potentially counteracting calming effects.

Choosing the Right Calming Supplement
The best supplement depends on your horse’s needs and circumstances:
- For Deficiency-Related Issues: Vitamin B1 is ideal for horses with suspected thiamine deficiencies, often linked to diet.
- For Muscle and Nerve Support: Magnesium is a versatile choice for horses in high-stress environments or with muscle tension.
- For Holistic Stress Relief: Ashwagandha may benefit horses needing overall stress management, particularly in performance settings.
- For Inflammation and Recovery: Resveratrol could support horses under physical or stress-related strain.
- For Focus Under Stress: Tyrosine may help horses needing mental clarity without sedation.
