Vitamin D levels low?
Mushrooms may be able to help.
According to researchers at the Boston University School of Medicine, the fungi - in powder form - might provide as much vitamin D as some supplements.
In the small-scale study, 30 healthy adults were given either vitamin D supplements or mushroom powder for 12 weeks during the winter. By the end of the study, researchers say the participant's vitamin D levels were virtually the same.
"These results provide evidence that ingesting mushrooms that have been exposed to ultraviolet light and contain vitamin D2 ... can improve the vitamin D status of healthy adults," said Michael F. Holick, the principal investigator, in a statement.
"Furthermore, 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."
While previous studies demonstrate that mushrooms can produce vitamins D2 and D4, this latest study detected several other types of vitamin D, including provitamins.
