The 15 Best Horse Calmers

Horses are very inquisitive and excitable. This excitability, however, makes them prone to becoming agitated, nervous or stressed.

Horse calmers are a great way to ease your horse’s anxiety and acute stress. These supplements come in various forms and can be either slow- or fast-acting.

No matter which one you choose, these calming aids are a great way to help your horse reduce their anxiety levels and risk of developing stress-related diseases.

In this article, we’ll tell you all you need to know about the different horse-calming supplements and help you choose the best horse calmer to use with your equine companion.

What Are Horse Calmers?

Horse calmers are supplements given to horses to lower their acute stress and anxiety levels.

Some calmers come in paste form and are given to the animal using a large syringe. These are quick-acting and help reduce stress and anxiety in horses.

Other calmers come in liquid or powdered form and are given daily to help build up the animal’s immune system and stress response, ensuring a more calm and relaxed horse.

What Are The Main Ingredients In Horse Calmers

Horse calmers, generally, contain the following ingredients:

  • Magnesium: This mineral is known for its calming and anxiety-reducing effects. It also helps horses better respond to insulin, helps prevent laminitis and protects against free radical damage and inflammation.
  • Tryptophan: This amino acid is a precursor of the neurotransmitter serotonin. Adequate serotonin levels help reduce anxiety, aggression, fear and stress.
  • Valerian root: This herbal supplement helps reduce stress and anxiety, and strengthens and supports your horse’s nervous system.

How To Choose A Horse Calmer

Keep the following in mind when choosing a calmer:

  • Supplement form: Consider which supplement form your horse takes more easily. Choose the form – whether paste, liquid or powder – that the animal finds easier to ingest. The best instant calmer for horses comes in paste form.
  • Cost: Horse calming supplements can be costly, especially if given to the animal daily. Therefore, consider how much money you’ll have to fork out daily and monthly. Buying a horse calmer in bulk can help horse owners save costs.

Except for using calming supplements, how else can I help my horse calm down?

Horse experts suggest that you use the following methods to help your horse destress during difficult or stressful situations:

  • Feed the animal smaller meals to reduce digestive stress
  • Give your horse a relaxing massage
  • Allow the animal to stretch and relax
  • Play soft music to help your horse unwind and destress

Can I also feed calming supplements to a pony?

Yes, many horse calming supplements also work on ponies. Calming supplements are a great aid to help your ponies overcome difficult and stressful situations.

Consult your supplier or veterinarian about the correct doses of calming supplements to feed your pony.

Are calming supplements legal?

Yes, many calming supplements are made from natural, laboratory-tested ingredients and do not contain any illegal substances. However, check with your supplier or veterinarian which products will be the safest to use – and won’t give a positive test result for banned substances – when participating in competitions.

Some horse enthusiasts argue that horses that are given calming supplements before an event or competition have an unfair advantage over other horses. Consult with your association to ensure which calming supplement will be allowed at events.

How long will it take for calming supplements to work on my horse?

This will depend on which type of supplement you’re using. Pastes, normally, take up to 90 minutes to have a calming effect, while powder and pellet supplements take longer to build up in your horse’s system. Even though paste supplements are considered the best instant calmers for horses, their effects are not as long-lasting as those of pellet and powder supplements.

Have your horse use a supplement for at least two weeks to see if it’s working optimally.
