Calming Fresh Packs


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.

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.

Amazing stuff!

This product had changed my gelding for the better ! He is a whole different horse ! Before he was spooky and reactive to everything ! He had been on the calming pellets for sixty days ! What a difference ! Thank You!

Jennifer Rodencal
Great value for a great product

I love this product, it takes the edge off but not the spirit. there have been several other ones that i have used and they just leave my gelding a zombie, this helps him manage his anxiety and still be the great horse that i love

Dawn Foust

Can definitely see a difference in my 4 yr old geldings attitude.

Lynne Mullens

This my second container of the calming pellets. I t really didn't make much of a difference. I even tried giving two scoops but unfortunately it didn't work out any difference

Judith Lynch

My mare appears to be responding to Formula 700 with a positive response. She has been even tempered more receptive towards her training and less stressed.


I'm really impressed! My 9 year old gelding who is an amazing barrel horse has really settled down on this product. He is definitely more on the anxious side and I needed something to just level him out that wouldn't take the run out of him. I'm very impressed ♥️

Lindasue Lewis

I am seeing a real difference in my mare's attitude, she is more focused and calmer which makes her a joy to work with again. Thank you for your product.


My reiner was having a hard time calming down after being shown by my trainer and then me taking him in green reiner - this supplement has helped him "chill" after going full throttle to going slow and quiet for me.
