Unlike if you follow a vegan diet, you shouldn’t need any supplements if you follow a nose-to-tail animal-based diet. That’s because you’ll get all of the macronutrients and micronutrients from muscle and organ meats.  That means that even if you’re a competitive athlete or a serious fitness enthusiast, you probably get enough protein from the meat you eat. Case in point: I don’t use protein powders because I get more than enough protein from red meat. However, if you absolutely don’t like the taste of organ meats or don’t have easy access to them, there is nothing wrong with using freeze-dried organ meats, such as the Grass-Fed Beef Liver capsules we sell at MK Supplements.
