Why Symphony?

A Horse of Course Symphony was created by Brad Kloss, an animal nutritionist with
more than 38 years of experience.


Brad started his career with one of the largest horse
nutrition companies in the world.
He spent months trying many different supplements
and nutrients for his own family horses, but never found an all-in-one supplement that
matched the quality he wanted.
There were far too many products claiming to do
different things to support equine health, and at a huge monthly cost.


Symphony uses the best ingredients in the industry and has been tested and proven! Brad took his
nutrition experience to team up with the biggest, most respected names in equine
nutrition worldwide: Zinpro®, Diamond V®, and Cool Stance®.


Today, Symphony by A Horse of Course is a very palatable, durable pellet that's made in a high-quality
manufacturing plant that only produces horse feed. You can fully trust Symphony's
source and ingredients for your horses.

Our Expertise Is Backed By:

  • 38 years of experience in animal nutrition

  • Studies from world-renowned companies that we partner with

  • Nutritionists, Ph.D.s, and Veterinarians

A quality product starts with quality ingredients. We use industry-leading ingredients that
have decades of proven equine research.

Symphony is the only supplement in the industry that combines all of these proven
ingredients at recommended levels — all in one product.

Feed Trial Rules

This Symphony Feed Trial offer is good for one participant per household and for new purchasers only.


Symphony should not be used with any other supplement during your 60-day trial. Since Symphony is a one-horse, one-bag, one complete supplement, you do not need anything else. Simply use it in conjunction with your normal hay program! 


After your 60-day trial period (and with each new 12-month subscription), you will be eligible to receive a free feed analysis with our Equine Nutritionist. You will also receive a free bag of Symphony at the end of your 12 months as our way of saying thank you for trying Symphony.


Symphony is the only supplement you need.  Welcome to the A Horse of Course family!
