Our 100% pure Chicken Hearts treats provide a high quality protein supplement along with an array of important vitamins and minerals. Heart is also an excellent source of CoQ10, or coenzyme Q as it is commonly called, which performs many complex biochemical functions. Coenzyme Q assists cells of the body in producing the energy needed for cell growth and maintenance, and the organs with the highest energy requirements, such as the heart and liver, have the highest concentrations of Coenzyme Q. In addition to its importance in cellular energy production, coenzyme Q also contains strong antioxidant properties as a free radical scavenger. Circulating in the blood, coenzyme Q is believed to prevent oxidation of LDL, which may help to prevent cardiovascular disease. It also serves to regenerate other antioxidants such as vitamin E. Our chickens are humanely raised, cage-free, on a vegetarian diet in the United States with no added hormones, steroids and no antibiotics ever. Proudly made in our bakery in Boulder, Colorado in the USA.  Ingredients: Chicken Heart
