“I have a question about using the selenium/Vit E supplement. If your horse has tested low for selenium can you use the regular Horse Guard and the Selenium/Vit E both? If selenium levels are within normal limits then just the Horse Guard is fine is that correct? Just wanting to find out if it is safe to use the 2 together. As I am assuming that the selenium/vit E is just that and does not have the vitamins and minerals of the Horse Guard?”
Answer by Ph.D. Equine Nutritionist, Kelsey Johnson Nonella:
Yes, you are safe to feeding both the horse guard and the selenium/vitamin E. It usually takes about 8 months to get horses to adequate levels but all horses metabolize selenium differently. Horses that are adequate should only receive horse guard. Like you assumed, the selenium/vitamin e product has no other vitamins and minerals.
