  • The best instant calmers for horses are fast-acting — often in paste-form and administered via a large syringe into the horse’s mouth — while other horse calming supplements that are fed daily take time to build up in your horse’s system and are more likely to be in powder or liquid form. They all have the same overall aim of reducing acute stress and overall anxiety, which should allow your horse to learn better and have a lower risk of stress-related disease.

    Any change of routine or novel situation can bring new stresses with it. In these situations, the best instant calmers for horses can help to “take the edge off”, leaving you with a more relaxed horse that may be safer to handle. Some are designed to work alongside a daily calming supplement, while others are effective on their own.

    How to choose an instant calmer

    Despite lots of anecdotal evidence to support their effectiveness, there is limited scientific research into how calmers and their active ingredients work in horses. Popular ingredients include:

    • magnesium, which is thought to produce an anxiety-reducing effect
    • tryptophan — a building block of serotonin, which is a neurotransmitter associated with lower levels of stress
    • valerian, which is thought to reduce anxiety

    We’d usually suggest to consider the form a supplement takes, but these all come in paste form. Instead it’s worth considering the time each one takes to act as although they’re billed as “instant calmers”, most take at least an hour or two to enter your horse’s system.

    Cost is another consideration – some of these syringes deliver multiple doses so are better value for money if they work for your horse. You’re also better off buying multipacks where available if you’re likely to require the calmer on multiple occasions.

    If you compete with your horse then it is important you make sure any supplements you use do not contain any prohibited substances.
