Not too much, no: Most adults need 5000-8000 iu of Vit D per day to attain optimal blood levels of 50-80. 4400 iu of D per day is quite safe. See http://tinyurl.com/2chkcer Vit D increases calcium absorption but doesn't affect serum calcium, which is controlled by the parathyroid gland. It's ideal to take Vit K with D. There are MUCH better multivits than Centrum silver-see http://tinyurl.com/mzrkbx8 and comment:
