Why is an Excess of Vitamin D Dangerous?
Vitamin D is a fat-soluble vitamin. In contrast to water-soluble Vitamins, the body cannot easily get rid of fat-soluble Vitamins. Therefore, supplementing too much can cause the accumulation of Vitamin D inside the body.
The exact mechanism of Vitamin D toxicity is complex and still poorly understood. In general, this can cause excess Vitamin D levels in the body to increase. It can get inside cells and overwhelm the signaling processes it controls.
One of them involves enhancing calcium absorption from the digestive system. Therefore, the main symptom of Vitamin D toxicity is hypercalcemia. High calcium levels can bind to other tissues and damage them.
Long-term high-dose Vitamin D supplementation poses a potential risk of toxicity if used improperly according to the dosage instructions of the doctor.
