What Is The Best Horse Calming Supplement On The Market?

What if I told you there was something you could do to make your horse calmer and more relaxed?

I bet you’d burst out laughing and tell me to pull the other one! But trust me on this, there are actually supplements out there that you can add to your horse’s dinner that will make him calmer, and so more receptive to your aids.

1. Formula 707 Daily Fresh Packs Equine Supplements Review

Formula 707 Calming Equine Supplement, Daily Fresh Packs, 28 Day Supply - L-Tryptophan, Thiamine & Magnesium Provide Support to Improve Focus in Horses

This is a complete feed that can really help keep your horse calm, collected and focused. It contains ingredients that are specific to maintaining a chilled out horse – which means a chilled out rider! This one offers support for the whole nervous system, making it ideal for those who want to maintain a calm demeanour long term.


  • Contains L-Tryptophan – This element is renowned for helping serotonin delivery and for decreasing anxiety, making it perfect for the horse who is naturally nervous.
  • Also contains Magnesium – Magnesium Oxide helps with bioavailability and can allow the Tryptophan to spread around the body doing its work.
  • Can help with weight gain – Keeping weight on older horses and certain breeds can be tricky, and this supplement can help put weight on and keep it there, thus improving the whole body system.
  • Ready made packets for convenience – No need to worry if you’re feeding your horse the right amount; it’s measured out for you so you don’t have to worry about whether or not you’re giving the correct dosage.


  • Apple flavor may be unpalatable – Some horses don’t like artificial flavourings so this may not be suitable for those who spit out anything that doesn’t taste like what they’re used to.


This is a fantastically convenient, easy to administer supplement that has proven results. Giving it to your horse can only do him good, due to the easily available minerals that can help the entire body function better.


2. SynChill Daily Horse Calming Pellets Review

SynChill Daily Horse Calming Pellets

This supplement is great for the horse who is naturally highly strung. It is equivalent in human terms to taking 5HTP – natural, harmless, and something which can really help with nervousness and unwanted, difficult behaviours.


  • Contains L-Theanine – This particular element can help with increasing calmness because it enhances activity in the hippocampus.
  • All natural ingredients – Most people don’t want to feed their horse anything artificial, so will love this supplement’s natural composition.
  • Palatable composition – Supplied in an alfalfa base, this one will be attractive and tasty to any horse, meaning that you can guarantee you can get it into him easily!
  • Developed by equine vets – In case you needed any other encouragement that this is a great supplement, the fact that it has been designed and is used by equine vets is a huge boost for its appeal.


  • It’s pretty pricey – Of course, we all know that we pay for quality. Luckily this supplement delivers, because it is an expensive investment.


A fantastic, all natural supplement that does exactly what it says on the tin. This one can be taken a few hours before a stressful event, or daily for the horse that is naturally highly strung to achieve a long-lasting calm.


3. Mare Magic Review

Mare Magic 32 oz

As we all know, mares (like some women!) can be a bit hormonal. This can result in some pretty hair raising rides, or even just a lot of drama on the ground, neither of which are ideal for a relaxing environment. You can get a supplement that is specific to mares to help her through this time and which will make her more calm and more fun to be around.


  • Tones the uterus and helps the reproductive tract – This means that your mare will be much more comfortable during her cycle, which will make her happier and less cranky.
  • Natural ingredients include raspberry leaf – Long used for humans as well as horses, raspberry leaf is specific to the female reproductive system and can help make things easier for horse and rider.
  • One pack lasts a long time – The amount provided will last approximately 240 days, making this a fantastic investment. Nearly a year’s worth of supplement for this price is amazing!
  • Can also be used for geldings – Although this supplement is made to be specific for mares, it can also be used to induce a calm demeanour in geldings, with great effect.


  • Can affect bowel movements – Because this product is very relaxing, it may have a similar effect on the bowels. Keep an eye out for any unusual movements.


This is a fantastic supplement for helping your mare get through her “time of the month” as well as the rest of the time. There is no need to put up with a “mareish” mare anymore! Just add a bit of this to her feed and be amazed at the change in personality.



We all know that supplements can really help with dietary issues, medical issues, keeping weight on and the like. But the fact that supplements can actually help keep your horse calm and relaxed too is an absolute godsend! Finding a supplement that contains natural ingredients and actually does what it’s meant to is even better. Have a look through the above and see which suits your horse the best, and you can thank us later.
