Women with higher vitamin D levels lived longer and had less inflammation, several new studies reveal.
In a survival study, researchers measured vitamin D levels in 714 women, aged 70 to 79, and followed up for six years. Women with the highest vitamin D levels, more than 27 nanograms per milliliter of blood, were 60 percent less likely to have died from any cause compared to women with the lowest levels. Doctors believe vitamin D may help control inflammation, immunity, blood pressure, and hardening of the arteries.
In an inflammation study, researchers measured the diets and vitamin D levels in 69 healthy women, aged 25 to 82, who had either high or low sun exposure. Vitamin D levels in the high sun-exposure group were 52 ng/mL compared to 30 ng/mL for low exposure. In the low-vitamin D group, one sign of inflammation was higher than in the high-vitamin D group, leading doctors to conclude that, “Low vitamin D levels negatively impact inflammation and immune response, even in healthy women.”
