Beef liver has been called nature's original multivitamin for good reason. Gram for gram it is the most nutrient-dense food measured by nutritional science, delivering heme iron, B12, retinol, copper, choline, folate, and riboflavin in concentrations no synthetic supplement can match in bioavailability. MK's Beef Liver is sourced from 100% grass-fed and grass-finished cattle raised on regenerative pastures in the United States, gently freeze-dried to preserve heat-sensitive nutrients, and third-party tested for purity. Packaged in glass bottles with metal lids. No plastic contact from production to supplement.
