Rating (out of 5): 3

Beef liver is considered a nutrient-dense organ meat, rich in high-quality protein, vitamins (notably B12, A, and folate), and minerals (such as iron and zinc), all of which play critical roles in supporting muscle health and function. Scientifically, adequate protein intake is essential for maintaining and repairing muscle tissue, and deficiencies in vitamins like B12 or minerals like iron can contribute to muscle weakness or poor muscle tone. Several studies have shown that supplementation with proteins, B vitamins, and iron can help address muscle weakness in deficient individuals. However, there is limited direct clinical research specifically examining beef liver as a treatment for "lack of muscle tone" (hypotonia) outside of addressing underlying nutritional deficiencies. The evidence supporting beef liver's use is thus based on its established nutritional content and the role of these nutrients in muscle function, rather than on targeted clinical trials. Historically, beef liver has been valued as a strength- and vitality-promoting food in various cultures, but its modern use for muscle tone is grounded more in its nutritional profile than long-standing tradition. In summary, while beef liver can support muscle health due to its nutrient density, direct evidence for its use in treating lack of muscle tone is moderate and primarily tied to correcting specific deficiencies.
