More on Vitamin D and Depression
We have recently written about the link between vitamin D and depression. While several studies have indicated that low vitamin D levels may be associated with depression, we lack randomized, controlled trials assessing the benefits of vitamin D supplements for the treatment (or prevention) of depression. A recent report from the Women's Health Initiative Calcium and Vitamin D Trial included 36,282 women (50 to 80 years of age) who were randomized to receive 400 IU vitamin D (with 1000 mg calcium) or to placebo.
