The 707 Calming pellets worked almost immediately on my nervous quarter horse gelding. He didn't worry about things anymore and was much calmer to ride. Highly recommend.

Description:

Formula 707 Calming contains COMPLETE support for the three processes that lead to a balanced central nervous system: serotonin, relaxation and energy metabolism. A horse that’s nervous, jumpy and easily distracted is hard to train, difficult to work with and dangerous to be around. While some horses are born nervous, others may suffer from environmentally induced stress. Among the symptoms of low magnesium are nervousness, muscle tremors, a lusterless hair coat and intolerance to work or exercise. Thiamine deficiency may be expressed in nervousness, irritability, excitability, elevated blood lactate and pyruvate, and muscle cramping. Both are more likely to occur in horses on a high-carbohydrate (i.e. high-grain) diet. Formula 707 Calming uses premium quality magnesium oxide to maximize bioavailability and combines it with two of the agents best known to have a calming effect in horses, thiamine and L-tryptophan.

The Most Complete Calming Support Supplement

Take control of your horse's behavior with our show-safe pellets. Whether you have a mare-ish mare or a horse with too much spook, this best-selling supplement is a comprehensive way to help take that unmanageable "edge" off. 

 

Specifically designed to address behavioral challenges, these pellets promote a calm and focused demeanor. Crafted with premium ingredients, they support mental well-being without compromising performance. Perfect for competitions or daily rides, Formula 707 Calming Pellets ensure a more enjoyable and manageable experience with your equine companion.

Setting Your Horse Up for Success

Formula 707 Calming Pellets for horses feature magnesium, L-Tryptophan, and thiamine, which support calmness and relaxation. Magnesium plays a role in nerve and muscle function. L-Tryptophan is an amino acid involved in producing serotonin, which influences mood. Thiamine (Vitamin B1) contributes to the normal functioning of the nervous system.

What makes Formula 707 Calming better than other solutions for anxious horses?

1. Triple-Action Approach

Other supplements focus on one ingredient to address a horse's nervousness. Formula 707 Calming provides substantial quantities of three ingredients that work synergistically together to promote relaxation.

2. Not a Sedative

Our pellets allow you to continue training as normal, with your horse retaining alertness and manageable energy. Calming works to take the edge off.

3. Show Safe

You can continue giving Formula 707 Calming pellets to your horse leading up to, and through the duration of a competition. Our customers show in a variety of disciplines and federation, and you can be assured that from the hunter ring to the racetrack, Calming pellets will not test.

4. Made In-House

Our pellets are produced in our own facility, and have been for decades. We're able to oversee every part of the manufacturing process to ensure your horse is getting the highest quality pellet. Best of all,  while other companies spend extra money on having someone else manufacture for them, we're able to pass those savings along to you.

Loved by thousands of horses and their people.

Formula 707 is the trusted choice of thousands of horse owners globally. From various disciplines and all ages, our community values the special connection that horses and humans have. We prioritize the health and happiness of your horse by formulating our supplements in collaboration with experienced veterinarians.

Thiamine (B1)

Supplementing Thiamine helps specifically with nervousness, especially for horses with high energy.

Magnesium

We use premium quality magnesium oxide, which maximizes bioavailability and efficacy. Many horses are deficient in magnesium levels, with common signs such as muscle tremors, a lusterless hair coat and intolerance to work or exercise.

L-Tryptophan

After absorbing L-Tryptophan, the body converts a portion into seratonin, which can help regulate a horse's mood.

Works well to calm but not dead head

The weaving stopped, his brain is back!

Recently started 707 calming after purchasing a horse who I found was a chronic weaver. I couldn’t keep any weight on him because of his weaving. He came to me rather underweight to begin with and I wanted to find something that would help support him and calm his anxiety. Now he stands quietly and eats everything I put in front of him. He is gaining weight because of it!

Pictures:
Before: eating while noticeably ribby.
After: no longer ribby after a bath.

Fiorenzo

My big boy was just a foal when I found him in Idaho. We walked to the gate of a HUGE Pasture with at least 15 horses at the back. I gave a huge whistle, no horses even turned their heads except a big colt. He turned and came galloping full speed. We didn’t move. He broke to a trot, stopped right in front of me and said “Hello!! Are you my mommy!!! That was twelve years ago. I remember like it was yesterday. I have kept him on formula 707 for years. He is everything to me.

Cool as a Cucumber

While a generally solid citizen, my horse can get tense & looky. I had tried your average magnesium supplement but never quite got that cool & relaxed feel that I like. Formula 707 did the trick. The little bit of L-Tryptophan was the key to “taking the edge off” without making him dull. Very satisfied with the results.

Excellent product

707 Calming is a great product. It worked quickly and has been just the right product to take the edge off my gelding. No issues with him eating it too dressed on his feed.

Great stuff

My sweet Levi had so much trauma from going through auction after auction till he landed in a kill pen and I found him. Nearly 5 yrs later he’s not 100% calm till I tried your calming pellets. I have to mix it with applesauce to get him to eat it but yesterday I was able to brush spots I couldn’t before and he no longer flinches on the one side when putting his halter on or taking it off. So glad I found your Formula 707 calming.
Thank you

Its working!

Not sure if you know the famous practice rope horse Jumanji. Well I swear our one horse is his brother from another mother lol. You would think he was abused you never know whats going to scare him but everything scares him. Its exhausting sometimes. He is on an all forage diet. Last year he was stuck in the field with no riding for only 2 weeks because of ice and we had to sedate him to get shod because he needs to be handled every single day or he thinks the whole world is out to get him. I started him on the calming supplement a couple months ago. We had the worst winter in years. He has been sitting in the field for 4 months. My daughter pulled him out of the field and rode him yesterday. She said he was oddly calm and such a joy to ride. This stuff WORKS!!!

FAQs

How long does Formula 707 Calming take to work? 

It takes 72 hours to be fully absorbed in the system, a couple weeks to begin to overcome some of the mental aspects of their anxiety, and 72 hours to leave the system.  

Can I use a loading dose?

Every horse is different, but a loading dose won’t necessarily “expedite” the process of seeing effects. However, for increased efficacy during potentially stressful events, it could be useful to double dose.  

Is Formula 707 Calming safe for insulin resistant/metabolic horses?

The binder we use is rice bran that has a 29% nonstructural carb level with a 33% fiber level. No other sugars added to the formula. Basically, feeding a daily serving of Calming is equivalent to feeding your horse 1 oz. of rice bran. Hope that helps! 

My horse is picky. How do I get him to eat Formula 707 Calming?

You can try giving small quantities in his grain and increasing over time until he's acclimated to the smell and taste. You can also try a binder such as apple sauce or molasses to hide it! 

Where is Formula 707 Calming made?

Calming is made in our own facility in Colorado - where we voluntarily adhere to the strict good manufacturing practices set forth by the National Animal Supplement Council.

Does Formula 707 Calming contain L-Theanine?

No - Formula 707 Calming does not contain L-Theanine, which was released by USEF as a prohibited substance in 2025. No Formula 707 products contain L-Theanine.

Will Formula 707 Calming stop cribbing?

It depends on the reason for the cribbing. If it’s a behavior issue out of boredom, that cannot be remedied with a supplement. If it is due to stomach pain, we would suggest our ULZERless pellets. They help to create a stronger mucus barrier and low the acid production.  

Is Formula 707 Calming a drug?

Calming is not a drug; it uses a triple-action approach with Magnesium, Thiamine, and L-Tryptophan—each being a mineral, vitamin, and amino acid, respectively—to help relax muscles and soothe the mind. This supplement is designed to support training for horses that tend to be a bit more high-strung. While it complements training, it does not replace it. 

Is Formula 707 Calming truly show safe?

Our research has shown that Tryptophan, as well as the other two natural active ingredients, are not prohibited in the AQHA, USEF, FEI, etc. We have many customers that actively use the product and have had their horses tested with no positive result. If you are concerned, please reach out to your association. 

Can I give two scoops of Formula 707 Calming?

Most horses can tolerate two scoops per day, and some horses have added efficacy with double the normal serving. Too much magnesium can cause loose stool, so make sure you are not supplementing large amounts of magnesium in addition to feeding Calming before trying this.

I'm a trainer and I have a big program I want to put on Formula 707 Calming. Are there bulk discounts?
