Fresh beef liver is a nutrient-dense organ meat known for being one of nature's most concentrated sources of essential vitamins and minerals. This economical cut provides exceptional nutritional value, offering high-quality protein while remaining low in calories. Beef liver is particularly rich in iron, providing approximately half the recommended daily amount for men in a single 3-ounce serving, making it an excellent choice for combating iron deficiency. It also delivers exceptional amounts of vitamin A, vitamin B12, folate, and other B vitamins that support energy production, immune function, and healthy brain and nervous system function.

Each serving contains approximately 133 calories and 20 grams of protein per 100 grams. The liver is also a significant source of essential minerals including zinc for immune support, phosphorus for bone health, selenium for metabolism, and copper for energy production. As a complete protein source, it contains all essential amino acids necessary for muscle development and tissue repair. Beef liver should be cooked to an internal temperature of 160°F and is best consumed in moderation, with recommended portions of 100-250 grams per week depending on individual dietary needs.
