Modern diets don't typically include high nutrient foods such as organ meats, and modern agriculture is producing plant based foods that don't contain nearly the same level of vitamins and minerals our grandparents enjoyed. In short, we often need to supplement but almost all store bought supplements are cheap, imported, synthetic vitamins which the body doesn't as easily recognise. This makes it harder for your body to absorb and use them efficiently. 
Put back the nutrients modern diets leave out with Beef Liver, Kidney, Heart, Spleen and Tripe providing a broad range of essential vitamins and minerals including Iron, Copper, Selenium, Vitamin A, Vitamin B3 (Niacin), Vitamin B9 (Folate), Vitamin B12, Vitamin C and Choline. Not many people like the taste of organ meats so this encapsulated product enables you to get the benefits without the taste!
