Guidelines recommend an intake of 400 international units daily after age 4 years, and many adults now take 1000 international units daily or more. When taken in doses that exceed what the patient needs, causing serum levels to exceed 250 mcg/L–1, Vitamin D can be toxic. Most references indicate that a level of 375 mcg/L–1 is associated with symptomatic toxicity.
