Rating (out of 5): 3

Beef liver has been traditionally consumed as a health tonic and is scientifically recognized for its dense nutritional profile, particularly for individuals experiencing debility—a general state of physical weakness or lack of energy. The organ is exceptionally rich in highly bioavailable iron, vitamin B12, folate, vitamin A (as retinol), and protein. These nutrients are critical for the maintenance of red blood cell production, energy metabolism, and overall cellular health. Scientific studies have demonstrated that deficiencies in iron and B vitamins, especially B12 and folate, can directly contribute to symptoms of fatigue and weakness. Supplementation with these nutrients, such as through beef liver, has been shown to correct anemia and improve energy levels in deficient individuals. However, while the nutritional rationale for using beef liver to address debility is strong, there are few controlled clinical trials directly testing beef liver as a treatment for general debility outside of the context of specific deficiencies. Most evidence is extrapolated from its ability to treat or prevent conditions like iron deficiency anemia and B12 deficiency. Thus, beef liver is scientifically validated as a supportive food for certain forms of debility related to nutritional deficiencies, but not as a universal remedy for all causes of weakness.
