"I use this when the warm days and cool nights cause digestive upset. I also use a probiotic at all times. I have seen great improvement in his digestion when I add digest support. The formula is very concentrated compared to other herbal brands so I actually use half the reccommended dose with great success. My horses love the taste and will lick it off the bottom of the bucket if I give it to them straight (like when I get there after feeding and see that evening temp is dipping 25-30 degrees below the daytime high)."
