Why do many horses calm down when fed NATURAL GLO?
A. NATURAL GLO contains B vitamins and tryptophan (an amino acid) that have been associated with a calming effect on animals and humans. However, the main reason that many horses changed from high-grain rations to NATURAL GLO rations seem calmer is that they no longer are eating a lot of starch from carbohydrates that tends to produce a ‘grain high.’ NATURAL GLO doesn’t provide nutrients that increase the glycemic response (increased blood sugar), so, often, the final result is a ‘calmer horse.’ Q.
