According to the National Institutes of Health (NIH), the safe upper limit for adults is 4,000 International Units (IU) daily. Knowing what is too much vitamin D per day is essential, as excessive amounts can cause significant health problems, notably hypercalcemia (elevated blood calcium levels).

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 typically appear when daily intake from supplements is at least 10,000 IU for an extended period, leading to excess calcium. This article outlines what are the symptoms of too much vitamin D in the blood, a condition known as hypercalcemia, and its health implications.

While essential for bone health, immune function, and more, a 2021 case report highlighted a man who accidentally took 200,000 IU of vitamin D daily, leading to serious toxicity and hospitalization. This incident proves that yes, you can take too much vitamin D3 daily, leading to a potentially harmful condition known as hypervitaminosis D.
