“I am giving my 13 yr old mare, Horse Guard and SmartDigest Ultra (pellet form). Since both supplements contain probiotics and prebiotics, is it safe to continue to use both products or should I only use Horse Guard? Thanks”
Answer by Ph.D. Equine Nutritionist, Kelsey Johnson Nonella:
It is perfectly safe to feed both products together, as you don’t have to worry about any vitamin and/or mineral toxicities. Extra probiotics and prebiotics are fine to feed to help out your mare’s digestive system.
