Rating (out of 5): 4

Fish liver oil, particularly cod liver oil, is scientifically recognized for its role in supporting the skeletal system due to its high content of vitamin D and vitamin A. Vitamin D is essential for calcium absorption in the gut, which is critical for bone mineralization and overall bone health. Deficiency in vitamin D can lead to rickets in children and osteomalacia or osteoporosis in adults. Numerous clinical studies have shown that supplementation with vitamin D, including from fish liver oil, can improve bone density and reduce fracture risk, especially in populations at risk of deficiency. Cod liver oil was historically given to children to prevent rickets, and this practice was later validated by research identifying vitamin D as the protective factor. Additionally, fish liver oil provides omega-3 fatty acids, which may have ancillary benefits for bone health by modulating inflammation, although the evidence for omega-3s specifically in bone health is less robust than for vitamin D. However, excessive intake of vitamin A from fish liver oil can be detrimental to bone health, so appropriate dosing is important. Overall, the use of fish liver oil to support the skeletal system is well-supported by both historical practice and scientific validation, primarily due to its vitamin D content.
