Synopsis

Source of validity: Scientific
Rating (out of 5): 4

Liver has been traditionally used in various cultures as a food to support eye health, but there is also solid scientific validation for its role in supporting the visual system. Liver is an exceptionally rich source of preformed vitamin A (retinol), which is crucial for the proper functioning of the retina and overall eye health. Vitamin A is a key component of rhodopsin, a protein in the eyes that allows for vision in low-light conditions. Deficiency in vitamin A can lead to night blindness and, in severe cases, complete blindness. Multiple clinical and epidemiological studies have shown that supplementation with vitamin A can prevent and treat vitamin A deficiency-related eye disorders. The World Health Organization recognizes vitamin A supplementation as a critical intervention to reduce childhood blindness globally. Beef liver, in particular, provides vitamin A in amounts far exceeding daily requirements in just a small serving. While liver is not used as a pharmaceutical intervention, its high nutrient density—especially in vitamin A—explains its reputation and scientific justification for supporting eye health. Thus, the use of liver to support the eyes is both traditional and validated by modern nutritional science.
