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.

Setting Your Horse Up for Success

While other calming supplements take a singular ingredient approach, we're proud to offer a potent, well-rounded supplement.

Like all our supplements, Calming pellets are house-crafted in our manufacturing facility in La Salle, Colorado where our team oversees all aspects of quality, purity, and potency.


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 synergestically 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.

A Three-Way Approach to Calming


Thiamine (B1)

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



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.



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

Calming is perfect for:

Horses who have difficulty focusing on training

Whether you are preparing for show season, or just trying to better your horse's training, Calming Pellets fed daily can provide the basis for progress with enhanced focus in the arena.

Magnesium helps to support the relaxation of muscles, allowing typically tense horses to release and better respond to your aids. The formula is not sedative, but instead is designed to take the edge off.

Horses who get anxious in new situations

We've all been on a horse that acts completely different the second you leave your barn. It can be especially stressful in a competition setting, where all nerves are running high. Feeding Calming daily can help take the edge off in training and preparation, and many of our customers will double dose the day before and days of competition, trail ride, etc. to help ensure their horse is in the best mindset to succeed.

Best of all, Calming Pellets do not contain banned substances from competition.

  1. Purchased for a particularly hot rescue mare and while it has not cooled her heels all the way, this product has definitely quieted her enough for her younger handler to make good, safe strides in training Hope as she gains weight, muscle and strength from extreme starvation.

  3. Truly made such difference with my horses one has a little spook and other one has a anxiety leaving the other horse and riding off but know they been on this for 6 months they have been great I can’t wait to try there fly pellets that’s what I’m going to try next.

  4. This supplement is a game changer for my 4-year-old mare. She traveled across the country and came to me overly nervous and anxious about everything. I dreaded riding her as it took everything I had to constantly reassure her in every corner. She tossed her head and would bolt or spook at the little noise or movement. Even her shadow was traumatizing. After less than two weeks, her demeanor has completely shifted. She no longer looks for things to spook at, her ears are on me, and she is more relaxed. I look forward to riding her and cannot wait to continue to develop her as the junior/children’s hunter that she was purchased to be. These videos were filmed 2 months apart. The last video was taken a week and a half into starting Formula 707 Calming.

Frequently asked questions:

  • Can this be used daily?

    Yes - Formula 707 Calming Pellets are safe to use on a continuous basis. Continuous administration is actually recommended, as it ensures that your horse maintains a calm disposition, rather than oscillating between levels of stress. For more intermittent and situation-induced reactivity, try our Formula 707 Calming Paste.

  • Can Calming Pellets be fed in conjunction with Calming Paste?

    Yes - Paste and pellets can be administered simultaneously. We recommend providing the pellets on a continual basis, and supplementing with the fast-acting paste as necessary (i.e. when traveling, competing, etc.).

  • Does this product help with ulcers?

    No - this product is not designed to help with ulcers. We'd recommend checking out ULZERless Pellets if your horse may be experiencing issues with ulcers.

  • Does this product help with sassy mares?

    Yes - many mare owners see great results by feeding Calming. The three active ingredients take a well-rounded approach to mare-ish behaviors, while other supplements marketed towards mares only contain one active ingredient.

  • Will this help a buddy sour horse relax?

    Yes, this should help the lack of ability to focus of a horse that is buddy sour. If you have specific circumstances (i.e. a show or clinic) where your horse may be alone, you are more than welcome to double the daily recommended serving the day before and day of for increased efficacy.

  • Can I use this product during horse shows?

    Yes - this product is show-safe! The active ingredients in this product are permitted in all federations.

  • My horse is smaller/larger than the average horse. How much should I feed?

    Our serving sizes are based off of the average 1100 lb horse. Serving sizes may be adjusted up or down in correspondence with weight. For instance, for a 500 lb pony, we'd recommend feeding half the recommended daily serving. However, you may safely adjust the serving down or up, depending on your horse's needs.

  • Do you offer free shipping?

    Free shipping is available on all orders over $100+. The 20 lb sizes will receive free shipping.
