Tag: Side effects of vitamin d

While vitamin D deficiency is a well-known health concern, a lesser-discussed but serious issue is excessive intake, known as vitamin D toxicity or hypervitaminosis D. It is caused almost exclusively by taking excessive doses of supplements, not from diet or sun exposure. Understanding what happens to your body when you take too much vitamin D is crucial for safe supplementation.

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. This can lead to a condition known as hypercalcemia, which is the main cause of the health problems you can experience if you have too much vitamin D in your body.
