Vitamin D does not occur naturally in the diet. Adequate amounts are gained through fortified foods, supplements, and exposure to sunlight. Vitamin D₃ is preferred. If calcium intake is not sufficient, vitamin D can promote bone decalcification. Vitamin D acts to increase the absorption of calcium and phosphorus from the intestine.
