Supreme Source Pork is hot extruded (which means it's processed under extreme heat and pressure) and made with feed grade ingredients, which are unfit for human consumption. It contains 26 synthetic additives (so it is not all-natural), it has 5 anti-nutrients including Peas, Lentils, and Faba Beans (which may interfere with the absorption of essential nutrients), and it has 4 other sketchy ingredients, including Brewers Dried Yeast and Natural Flavor.

Warning Due to this being a grain-free food that contains legumes or potatoes this Supreme Source recipe may be implicated in the FDA's ongoing investigation into diet-related Dilated Cardiomyopathy (or DCM), a potentially fatal heart condition.
