The Science
Beef liver is excellent for muscle building due to its high protein content (20.4g per 100g, +41% DV) which provides essential amino acids for muscle protein synthesis. Additionally, it is rich in iron (+27% DV) and zinc (+36% DV), which support oxygen delivery to muscles and testosterone production, respectively, both critical for muscle growth and recovery. The high copper content also aids in energy metabolism and connective tissue formation.
Recommendation
Include beef liver in your diet 1-2 times per week as a nutrient-dense protein source, but balance it with other protein foods to avoid excessive vitamin A intake.
