Tag: Symptoms of excess vitamin d

According to the National Institutes of Health, symptoms of vitamin D toxicity are most likely to appear when a person’s daily intake is at least 10,000 IU. When your vitamin D is high, it can lead to a serious condition called hypervitaminosis D, which causes a dangerous buildup of calcium in the blood.

While vitamin D is crucial for bone health and immune function, excess intake, primarily from supplements, can lead to serious health problems. Unlike dietary sources or sun exposure, supplemental D3 can cause toxicity if taken in very high doses over extended periods, a condition known as hypervitaminosis D.
