Cod liver oil contains high concentrations of the omega 3's eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). As the oils are produced in the liver, they also contain natural levels of vitamins A and D. Our High Strength Cod Liver Oil capsules 1000mg are the perfect choice to support general health and wellbeing. Glucosamine is naturally produced by the body to support the growth of healthy joint tissue. To ensure that each tablet is consistently of the highest quality, glucosamine is combined with low levels of potassium chloride (2KCl). This acts to stabilise the glucosamine.
