“My horse has been on your products for the last several years, and seems to be doing well on it. I’m glad I can buy from a local company that understands our PNW special needs. I was just curious what the source of Vitamin E is – is it the natural or synthetic analogs for Vitamin E? Thank you for your help!”

Answer by Ph.D. Equine Nutritionist, Kelsey Johnson Nonella:
Great to hear your horse is doing well on our products. We use the synthetic form on Vitamin E in our products which about 60% is available to the horse. It works well to meet most horse’s requirements when paired with good-quality hay. However, extruded soybeans are naturally high in Vitamin E, and therefore, our extruded soybean based products, such as Super Weight Gain, provide both the synthetic vitamin E found in the guaranteed analysis but also high levels of natural vitamin E as well.

We have 15 of our own horses that range in age from weanlings to 24 years old, with many of the horses being high level performance horses. All of them have been on Trifecta for years, and have adequate levels of Vitamin E. We formulate all of our products with the horse’s best interest in mind, especially Northwest horses.
