Not only does cod liver oil contain omega-3 fatty acids which could help to reduce the risk of blood clots, cardiovascular disease, and ease joint pain, but it also contains vitamins A and D which are essential to the body’s healthy function.
Vitamin A is great for your skin, immune system, eye health and reproduction, while vitamin D can help to prevent bone issues in the elderly and birth defects in pregnant women.
Most cod liver oil supplements contain around 5 micrograms of vitamin D, which is half the recommended daily intake of 10 micrograms suggested by the NHS, so you may need to top up with a separate, small dose of vitamin D.
