Vitamin D is not actually a vitamin, but a hormone. Vitamins are not able to be made but must be obtained from the diet. Ninety to 100% of Vitamin D Hormone is made in the skin from cholesterol under the influence of UVB radiation.
If you go out in the summer sun in your bathing suit until your skin just begins to turn pink, you make an average of 20,000 international units (IU) of Vitamin D in your skin. Translation: a few minutes in the midday summer sun produces 100 times more vitamin D than the government says you need!

Potential side effects of Vitamin D3 Hormone
Taking more than 40,000 iu per day can result in calcium levels that are too high. (American Journal of Clinical Nutrition, Vol. 69, No. 5, 842-856, May 1999) These symptoms include anorexia, nausea, and vomiting, frequently followed by polyuria (urinating a lot), polydipsia (drinking a lot), weakness, nervousness, pruritus, and ultimately, renal failure. If vitamin D3 is too high (>100 ng/dL), it may cause atrial fibrillation (Circulation, 2011; 124:A14699). Monitoring Vitamin D levels and adjusting the dose as required avoid these potential side effects.
