The RDA for vit D is set ridiculously low at 400iu – in America it has just been raised further, but I like people to have at least 2,000iu and many people I recommend 10,000iu daily. At this level of dosing there are no side effects and no toxicity. In winter in our climate we should all be taking vitamin D. ................
