Is it Ok to take vitamin D without prior blood testing? I.e. is it harmful to take vitamin D if ur body happened not to be at defeciency of it?

Dr. Zakia Dimassi Pediatrics
Any vitamin taken without having actual deficiency may eventually lead to side effects. And although the majority of the Lebanese population seems to have vitamin D insufficiency or deficiency, it is recommended that you have a baseline measurement of the level of vitamin D in your blood to make sure that you are actually in need of vitamin D supplements, the needed dose, the duration of treatment, and to later on do a follow-up vitamin D level to assess for proper response to the supplements and whether or not you need to keep taking vitamin D.
