Horizon uses both grains and vegetables as its carbohydrate source, depending on the formula.  In Horizon Complete formulas, we use high quality grains such as rye, hulless barley and hulless oats.  In our grain-free formula, Horizon Legacy, and our raw frozen diet, Horizon Pure, we use fruits and vegetables.

In those formulas with grains, Horizon uses rye, barley and oats.  Barley and rye have five times more fiber than other wholegrains which steadies blood sugar levels and may help to avoid heart disease.  These grains are especially abundant in the B vitamins, which are essential for energy metabolism and the nervous system and vitamin E which is a strong anti-oxidant.
