What is the tolerable upper amount of daily Vitamin D intake? If I take two or three Os-Cal tablets with Vitamin D, will that be too much?
It is generally recognized that the tolerable upper intake of Vitamin D from dietary sources and supplements combined is around 2000 IU. Therefore, taking two or three of these tablets per day will provide between 800 and 1200 IU per day, well below the safe upper intake limits recommended by the U.S. National Academy of Sciences.
