Synopsis

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

Fat liver oil, more commonly known as cod liver oil, is widely used to support eye health, and this use is supported by scientific evidence. Cod liver oil is a rich source of both vitamin A and omega-3 fatty acids, notably EPA and DHA. Vitamin A is essential for the maintenance of normal vision; its deficiency can lead to night blindness and, in severe cases, complete blindness. The scientific community recognizes vitamin A as a critical nutrient for the retina, particularly for the formation of rhodopsin, a protein in the eye that absorbs light in the retinal receptors.

Clinical studies and nutritional guidelines consistently cite cod liver oil as an effective dietary source for vitamin A. In addition to vitamin A, the omega-3 fatty acids in cod liver oil have been researched for their role in supporting retinal health and possibly slowing the progression of age-related macular degeneration (AMD). For example, a review in the journal Progress in Retinal and Eye Research (2016) details the positive impact of omega-3 fatty acids on visual development and retinal function.

Overall, the use of cod liver oil to support the eye body system is justified primarily by the scientific understanding of its nutrient composition and the established roles of vitamin A and omega-3s in ocular health. However, excessive intake of vitamin A from cod liver oil can be toxic, so its use should be carefully monitored.
