Vitamin D has the greatest potential for toxicity of all the vitamins, though amounts up to 1000mcg are generally agreed to be safe in adults. Younger adults or children may supplement up to 400iu daily. Vitamin D is theoretically contraindicated while taking warfarin (albeit no case of increased bleeding has ever been reported) and verapamil medications. Oestrogen-based hormone medications may increase blood levels of vitamin D (and hence improve bone density).
