Selenium may improve cervical cell health

The surface of the cervix can develop abnormal cells as a result of human papillomavirus, but inflammation and oxidative stress may also play a role. The condition is called cervical intraepithelial neoplasia (CIN), or cervical dysplasia.

In this study, 56 women diagnosed with CIN, grade 1, took a placebo or 200 mcg of selenium per day. After six months, 88 percent of the women taking selenium had improved cervical cellular health, compared to 56 percent for placebo. The selenium group also saw a 23 percent increase in total antioxidant capacity compared to 5 percent for placebo; fasting blood sugar levels decreased 7.2 percent compared to a 1.4 percent increase; insulin levels decreased 34.6 percent vs. 17.3 percent; insulin resistance decreased 39.4 percent vs. 17.8 percent; and signs of oxidative stress fell 26.4 percent compared to a 1.7 percent increase for placebo.
