Question

Quizplus · Accepted Answer

Skin produces previtamin D when exposed to sunlight, which is then converted to vitamin D in the body. Vitamin D is important for bone health and various other functions, but excessive intakes can lead to toxicity. Rickets is actually caused by vitamin D deficiency, not excess. Pellagra is a deficiency disorder of niacin (vitamin B3). Vitamin C is necessary for proper collagen formation, not vitamin D.
