Cod Liver Oil in older persons

Steve: Cod liver oil is a traditional source of vitamin D in Iceland, and regular intake is recommended partly for the sake of health. A British Journal of Nutrition study discovered that intake of aged participants was positively associated with serum vitamin D3 25(OH)D levels. Individuals with intakes of less than once/week, one to six time(s)/week and daily intake had concentrations of approximately 40, 50 and 60 nmol/l respectively. This is awesome!
