Mushrooms Contain as Much Vitamin D as Supplements
(Ivanhoe Newswire) -- Researchers from Boston University School of Medicine have found that eating mushrooms containing vitamin D2 can be as effective at increasing and maintaining vitamin D levels as taking supplemental vitamin D2 or vitamin D3. The findings are published in the Federation of American Societies for Experimental Biology Journal.
The randomized study involved 30 healthy adults. They took capsules containing 2,000 International Units (IU) of vitamin D2, 2,000 IU of vitamin D3, or 2,000 IU of mushroom powder containing vitamin D2 once a day for 12 weeks during the winter. The levels among the three groups increased gradually and peaked at seven weeks and maintained for the next five weeks. After 12 weeks, the levels were not significantly different statistically than those who ingested mushroom powder. “We found ingesting mushrooms containing vitamin D2 was as effective in raising and maintaining a healthy adult's vitamin D status as ingesting a supplement that contained either vitamin D2 or vitamin D3,” principal investigator, Michael F. Holick, was quoted as saying. For more information go to: http://www.faseb.org/News-and-Publications/News-Room.aspx#sthash.n8NAbeZw.NMNcWrZL.dpbs.
