It is a concentrated source of Coenzyme Q10, CoQ10, that is needed for basic cell function and optimizing the rhythm of heart beats. The heart contains about twice as much elastin and collagen than regular meats, which is important for healthy joints. More importantly, the heart is an important source of taurine, an important amino acid needed for vision, digestion, heart muscle function, and overall immune system. Lack of this amino acid results in severe health repercussions. We recommend that heart should be about 10% of your dog or cat's diet.
