It can: Unusual tho. Mayo study gave 50, 000/iuday & found hypercalcemia . 2, 000iu should not get u in2 trouble unless u r very sensitive 2vd. U only need a max of 2, 000iu/day. Save ur money.

If too high: You can get high calcium if your vitamin d level is too high. 4000 iu is an acceptable dose if your level is current very low and need to be raised up. The only way you will know for sure if you are getting too much is to get retested after being on the replacement dose for a short time. The main thing is to follow up with the doc that started the replacement to remeasure levels.

DON'T REALLY NEED 4,000iu tho, some studies say 800-1000iu. 4,000 will not cause a problem at all. just 2X$

It all depends on the current level. The Endocrine Society and American Association of Clinical Endocrinologists (AACE) recommends at most 4000 IU for Vitamin D Deficiency.
