FAQ:

Q: How much vitamin D is too much?

A: Too much vitamin D-3 has health risks. The recommended intake of vitamin D is 200 international units, or IU, per day for adults 50 years and younger, and 400 to 600 IU for adults over 50 years of age. Vitamin D toxicity, also called hypervitaminosis D, can result when you take too much vitamin D-3 in supplemental form.

Q: Is 1000 IU’s of vitamin D per day enough?

A: A daily vitamin D intake of 1000-4000 IU (25-100 micrograms) should be enough to ensure optimal blood levels for most people.

Q: What is the therapeutic dose of vitamin D?

A: The American Academy of Pediatrics recommends 400 units/day of vitamin D in infants and adolescents. Clinical data are not yet sufficiently robust to make definitive recommendations for therapeutic dosages of vitamin D; however, in the elderly, 700 to 1,000 units/day have been shown to reduce the risk of falls.
