Learn how to use natural horse calming supplements like NAF Oestress and TopSpec Calmer to reduce anxiety in your horse, with practical steps and expert tips.
Quick answer
To calm your horse naturally, start by identifying the source of anxiety, then choose a supplement that targets that specific trigger—such as NAF Oestress for hormonal balance or TopSpec Calmer for situational stress—and introduce it gradually into their feed.
Why natural calmers over sedatives?
Natural horse calmers work with your horse's physiology rather than masking symptoms. They are safer for long-term use and avoid the side effects of pharmaceutical sedatives, such as drowsiness or loss of coordination. However, they require consistency and may take a few days to show effect.
Choosing between hormonal and situational calmers
Not all anxiety is the same. Mares in season often benefit from hormonal support like NAF Oestress, which uses herbal ingredients to encourage regularity. For horses that spook at shows or during travel, a situational calmer like TopSpec Calmer is designed to help them cope with acute stress without dulling their responsiveness.
How to introduce a calming supplement in 4 steps
- Step 1: Assess your horse's anxiety triggers: Observe when your horse shows signs of stress—during riding, at competitions, when travelling, or around other horses. Note whether the behaviour is seasonal (e.g., mares in heat) or situational (e.g., new environment). This determines whether you need a hormonal or general calmer. A common mistake is assuming all anxiety is the same; matching the supplement type to the trigger improves results.
- Step 2: Select the right supplement: For mares with hormonal mood swings, choose NAF Oestress Liquid. For general anxiety during travel or competition, choose TopSpec Calmer. Read the label to ensure it matches your horse's weight and activity level. Check the dosage instructions carefully—some calmers are for daily feeding, others for event-day use only.
- Step 3: Introduce gradually into the diet: Start with a half dose for the first 2–3 days, mixed into a small amount of feed that your horse eats readily. Gradually increase to the full recommended dose. This helps the horse accept the taste and allows you to monitor for any digestive upset. If your horse refuses the feed, try mixing with a tasty base like NAF Mint (a natural appetite stimulant) to encourage consumption.
- Step 4: Monitor and adjust: Observe your horse's behaviour over 7–10 days. Note any reduction in spookiness, improved focus during work, or calmer demeanour in stressful settings. If no improvement, consider a different product or consult your veterinarian. Natural calmers are not instant fixes; give them at least a week before judging effectiveness.
