  • In 2015 Multiple Sclerosis published a retrospective study based on 953 MS patients and 1717 controls which found that the use of cod liver oil during adolescence was associated with a lower incidence of MS – likely due to the vitamin D3 supplied by cod liver oil (low vitamin D is a risk factor for MS).
