February 13, 2009 --Are you carrying extra pounds? Part of the problem may be low vitamin D levels. A study in California found that women with insufficient levels of vitamin D were about 16 pounds heavier and had greater body mass than their counterparts with sufficient levels of vitamin D.
Vitamin D regulates bone metabolism. It is mostly obtained through exposure of the skin to direct sunlight.
The study is reported in the Journal of Clinical Endocrinology and Metabolism.
