Vitamin D reduces the risk of fibroids
Circulating vitamin D levels were low in women with uterine fibroids
by Newsletter Editor
Fibroids are non-cancerous tumors that form a mass in the uterus of premenopausal women. In this study, doctors measured vitamin D levels and sun exposure in 1,036 black and white women, aged 35 to 49, and used ultrasound to detect uterine fibroids.
Half of the white women had sufficient levels of vitamin D, which doctors said was at least 20 nanograms per milliliter of blood, while 10 percent of black women had sufficient levels.
Compared to those whose vitamin D levels were low, women with sufficient circulating vitamin D levels were 32 percent less likely to have a fibroid, regardless of race.
In 2011, the U.S. increased its recommended dietary allowance for vitamin D to 600 IU per day for most people.
