Excess vitamin D
Too much vitamin D can be harmful. Vitamin D is stored in fat cells and can build up over time, leading to high calcium levels in the blood (hypercalcemia). High calcium levels can cause nausea, vomiting, confusion, and kidney problems. Calcium stones in the kidney can also be a problem.
Bottom line
Vitamin D is a nutrient that is essential for good health. It can be obtained from sun exposure, food sources, and supplements. While most people get enough vitamin D from these sources, some may need to take supplements to ensure they get this nutrient.
Vitamin D is an essential nutrient that helps the body absorb calcium and phosphorus. These minerals are necessary for strong bones and teeth.
