Correct Vitamin D Dosage

by Dr. Randy

A new study published in the Feb 2011 issue of the Anticancer Research journal confirms that Vitamin D in the range of 4000-8000 IU is necessary for adults to maintain an adequate blood level of vitamin D to prevent chronic disease, including diabetes and cancer. This level of supplement intake contradicts the recent recommendation of the US Institute of Medicine, which would limit intake to much lower levels. That recommendation proved very controversial and many vitamin D experts complained that their advice was spurned by the recommendation committee. This study from the University of California, San Diego School of Medicine and Creighton University School of Medicine in Omaha shows the wisdom of the Vitamin D Council’s recommendation that adults take 5,000 IU of vitamin D3 per day.

My recommendation is that adults continue to take 5,000 IU Vitamin D3, children 2,000 IU, and infants 35 IU per pound of body weight (or 400-1,000 IU depending on weight).
