Vitamin D plays an important role in maintaining your overall health. It’s necessary for the growth and development of your muscle cells and maintaining skeletal health. Vitamin D deficiency is extremely common and as per the National Institutes of Health in the USA, its deficiency affects around 1 billion people worldwide.
To combat the deficiency, many people use vitamin D supplements that are considered safe and non-toxic. However, toxicity is a possible outcome when consumed in large unhealthy doses. Vitamin D toxicity, also called hypervitaminosis D, is a rare but potentially serious condition that occurs when you have excessive amounts of vitamin D in your body.
