According to Wahls, beef liver is an excellent source of B vitamins, includingfolate, riboflavin, niacin, and cobalamin (B12). In fact, she says it's superior to greens when it comes to B12, which is not readily available in plants.
Beef liver also contains one of the highest sources of nonsynthetic, preformed vitamin A (aka retinol). "Three ounces of this organ meat provides around 7,900 micrograms of vitamin A, equaling about 883% of the recommended daily intake (RDI)," registered dietitian Molly Knudsen, M.S., RDN, tells mbg.This essential micronutrient is critical for immune functioning and difficult to find in most foods. "It's different from beta-carotene, which is what most vitamins/prenatals use," LeVeque explains in her Instagram caption.
In addition to its vitamins and minerals, beef liver "is a great source of high-quality protein to boost the metabolism while also being a good low-calorie and low-carb option," says dietitian Priscilla Blevins, M.S., R.D., L.D.
