Beef liver is the earth’s original (and best) multi-vitamin. An amazing source of vitamins A, B2, B3, B5, B6, B7, B9 and B12 as well as minerals copper, phosphorus, selenium and iron. In terms of variety and density of micronutrients, no other natural food really stacks up. This is especially true due to all the nutrients in liver being in the most bioavailable (useable) format for humans. Like all of our nose-to-tail supplements, our beef liver capsules are made from cattle that are 100% grass-fed and completely free from antibiotics, hormones and foods contaminated with fertilisers, pesticides or any other artificial chemicals.
