I know, but capsules are more convenient and don't cause oily gross feeling in my mouth (I suppose the oil could be soaked into something)
those pills contain A, D, E, C, B1, B2, B6, B12, niacin, biotin, folic acid, magnesium, calcium, potassium, zinc, iron, manganese, copper, iodine, chromium and selenium + some antioxidants (various plants extracts)
taking some of these together impacts absorbability but I can't be bothered to get separate pills
> I also have vitamin d3 but I'm not sure if I should take it because there is vitamin d3 in cod liver oil already.
depends on the dose, but it's not that easy to overdose vitamin D (although it is easier than other vitamins since it's not water-soluble)
