Tag: Health risks of high vitamin d

While vitamin D is crucial for bone health, immune function, and overall well-being, excessive intake can lead to serious health problems. Taking too much vitamin D through supplements, a condition known as vitamin D toxicity or hypervitaminosis D, can cause a dangerous buildup of calcium in the blood.
