Best Horse Calming Supplements

Here we take a look at the best horse calming supplements available to purchase over the counter, or online.

Not all horses suffer from stress, anxiety and nervousness, but you will find many that do. It can be pretty stressful to watch your horse if they exhibit these symptoms consistently and if you are regularly dealing with a particularly hot horse you could be putting yourself in danger. The best horse calmers can be effective and reliable.

Many owners choose horse calming supplements to take the edge off and they can really make the difference when it comes to safe handling and riding. They can also make your horse feel much more relaxed and at ease in their surroundings. Most calming supplements work in a similar way however the ingredients in the formulas vary enormously. This is why it is important to be in the know about what you’re feeding your horse. You certainly don’t want to make the situation worse for yourself.

Calming supplements can help your horse become the best version of themselves and assist in relieving them from stress, anxiety and nervousness. These supplements are designed to help horse’s that need them the most, but should never replace proper handling and training.


Let’s take a deeper look into calming supplements for horses and some of the best calming supplements available on the market to buy to help you with your search.


Why Use a Horse Calming Supplement?

Calming supplements are generally only used for horses that really need them. If your horse exhibits the odd spook now and again or occasionally gets a bit full of themselves this is not a situation where we would recommend your horse needing a calmer. This is just life and individual personalities.

When we talk about horses having a real need for calming supplements we are referring to those that are often anxious, nervous and stressed in daily life. This can be challenging for any owner and often a calming supplement can help relieve this behaviour by keeping your horse cool, calm and collected.

Another valid reason horse calming supplements are used is when a horse gets stressed in particular situations such as at a competition where nerves are high, travelling the horsebox (which can often be scary for horses) or even a vet visit (yes your equine friend is well aware an injection is looming!). In these types of situations, calming supplements can be an absolute godsend.

Let’s take a look at some of the key situations when you may choose to use horse calming supplements:

  • Nervousness takes over and your horse finds dealing with day to day life worrying
  • Your horse suffers from stress and anxiety on a day to day basis
  • You have a hot or excitable horse that needs to chill out
  • Your horse finds competing at competitions stressful and worrisome
  • Travelling in the horsebox or trailer makes your horses nervous or anxious
  • Your horse has been moved to new surroundings and is struggling to cope with the change

These are just a few of the most common reasons why you may choose to use calming supplements to help your horse through difficult times.


Best Ingredients in Horse Calming Supplements

So what can be found in your horse’s calming supplements?

There are so many types of ingredients that can be found in horse calming supplements and with so many different combinations and formulas available, it can be difficult to decide what would be best to buy. You will find that one type works much better for your horse than another will. Trial and error are usually key. Combinations of ingredients in the formula usually work best and provide the most all-round relief. Always ensure you read the label of ingredients on the packaging carefully so you are in the know about what you are administering to your horse.

With that being said, here are 5 of the very best ingredients you will most commonly find in horse joint supplements:


Magnesium sulphate is quite possibly the most popular ingredient that can be found in horse calming supplements. It is true to say that many horses suffer from a magnesium deficiency which can often leave them feeling nervous and with excess excitement. Magnesium provides a clear all-round calming effect for horses. Many studies have shown Magnesium to have significant soothing and calming effects. Daily feeding has also proven to have a noticeable effect on anxiety.


Tryptophan is referred to as an amino acid that is said to have a significant calming effect on horses. It is used regularly in horse calmer supplements and is often high up the list of ingredients, but there is little to no research to suggest it has a valuable effect on calming horses. It is very possible however that by combining this ingredient with others, such as Magnesium sulphate, it may have an enhanced effect on calming your horse. Many believe Tryptophan is a must-have ingredient in supplements of this nature.

Thiamine and Niacin

Thiamine and Niacin (otherwise referred to as B vitamins) are considered to be a very important addition to your horse’s diet. B vitamins are regularly found in calming supplements. Feeding at much higher levels has historically been known to calm nervous or anxious horses and help them stay relaxed and comfortable, even in particularly anxious times.

You will often find Thiamine and Niacin together in formulas for calming supplements as they work together hand in hand for a maximum effect. These won’t necessarily work for all horses, but the success rate in using these vitamins as calmers is exceptionally high.

Vitamin E

Vitamin E is a very valuable ingredient in any horse supplement and fresh pasture is usually your horse’s main source of intake. Fresh pasture isn’t always readily available to your horses and despite providing hay as the next best option, Vitamin E levels decrease as soon as the pasture is cut, meaning your horse may be lacking some nutrients.

Vitamin E is a very potent antioxidant that works to help your horse’s body deal with stress, illness and certain medical conditions and is a key ingredient in any good horse calming supplement.

A Variety of Herbs

Herbs can be a great natural alternative for calming horses. They are becoming more and more popular to use amongst owners and you will find that many commercial horse calmers now include at least one herb into the mix.

It is not uncommon to see Chamomile in many horse calming supplements and is a great addition to any formula. It has been used as a natural remedy in human medication for years and is generally safe for most people and animals to take. Other herbs you may notice included in horse calmers are Vervain, Valerian and HOPS. Be careful if you are giving Valerian to horses at competition. It is actually a banned substance under FEI and Jockey Club rules.
