Eggs are often recommended as a good source of Vitamin B12, a nutrient that supports nerve function and metabolism, among other body processes. While eating eggs can certainly help you meet your daily B12 needs—packing 0.5 micrograms, or 19% of your Daily Value per egg—several other foods provide significantly more of the vitamin per serving.

Beef liver is one of the most concentrated sources of B12 you can eat, providing nearly 3,000% of the DV per 3-ounce serving.
In addition to B12, beef liver is packed with protein plus critical vitamins and minerals, like iron, zinc, folate, vitamin A, and choline. Beef liver is especially high in vitamin A, with a 3-ounce serving providing 891% of the DV.
Because vitamin A is fat-soluble and eating too much could lead to vitamin A toxicity, beef liver should only be enjoyed occasionally and in small portions.
