Vitamin D toxicity is almost always caused by taking too high a dose of vitamin D supplements, rather than from eating too much vitamin D -- rich food or from sun exposure. When you take in too much supplemental vitamin D, the levels of calcium in your blood can get too high. The “safe upper limit” of vitamin D for adults is 4,000 international units (IU) a day.
