Take Vitamin D Pills Only If You Have a Deficiency

An editorial in the February 19, 2015 Journal of the
American Medical Association states that Vitamin D,
in combination with calcium, has been shown to be
good for your bones. However, Joanne Manson, the
author of the editorial, says that there is no good
evidence that large doses of vitamin D prevent
cancer, cardiovascular disease, diabetes, autoimmune
disorders, depression, infection or other maladies.
She heads a study of 25,875 people across the United
States to see if vitamin D pills prevent these
conditions. Results will be available in two years.
Doses of vitamin D greater than 4,000 IUs increase
risk for kidney stones, calcification of blood
vessels and even the very cardiovascular disease you
were seeking to prevent. The dose of vitamin D
recommended by the National Academy of Sciences is
600 international units daily for those up to 70
years of age , and 800 IU for those over 71.
Many people can get all the vitamin D they need
without pills, from a few minutes of exposure to
sunlight three or four days a week, or four servings
each day of vitamin D-fortified foods such as milk,
yogurt, soy beverages, orange juice or cereals, plus
fatty fish twice a week.
