If You Choose to Take Oral Vitamin D, How Much Should You Take?
June 28, 2008
New research has once again placed optimum vitamin D intake at much higher than the current recommended amount.
The study of 138 subjects suggested a daily dose of 3800 IU for those with adequate blood vitamin D levels, and 5000 IU each day for those who are vitamin D deficient.
The current recommended intakes for vitamin D are as low as 200 IU daily for those aged 19-50, and go only as high as 600 IU daily for those over the age of 70.
