Report: We don't need more vitamin D, calcium
from The Atlantic
In a report likely to send shock waves through the dietary supplement industry, the Institute of Medicine released new Dietary Reference Intakes for vitamin D and calcium. The report summary says Americans are getting all the vitamin D and calcium we need, and we do not need more: "The committee emphasizes that, with a few exceptions, all North Americans are receiving enough calcium and vitamin D. Higher levels have not been shown to confer greater benefits, and in fact, they have been linked to other health problems, challenging the concept that 'more is better.'" In an account of the report in The New York Times, Gina Kolata writes that the committee was puzzled about how vitamin D became the hot nutrient of the year. Sales rose 82 percent from 2008 to 2009.
