Contraceptives containing estrogen tend to boost vitamin D levels in women

Contraceptives containing estrogen tend to boost vitamin D levels in women

Researchers have reported that vitamin D levels could fall when women stop taking birth control pills or other contraceptives with estrogen.

The vitamin plays a part in the immune system and in maintaining calcium level in the blood, influencing bone health. When body comes in contact with sunlight, it produces the vitamin. Researchers said that when a woman is pregnant, she produces higher amounts of vitamin D to boost fetal bone development. Pregnant women are highly vulnerable to experience vitamin deficiency.

Study first author Dr. Quaker Harmon, postdoctoral fellow at the US National Institute of Environmental Health Sciences, said that their findings are an indication that women could face the risk of developing vitamin D deficiency the moment they chose to conceive.

In a news release from the Endocrine Society, Harmon said, “For women who are planning to stop using birth control, it is worth taking steps to ensure that vitamin D levels are adequate while trying to conceive and during pregnancy”.

The research, including blood samples of around 1,700 black women in the Detroit region, demonstrated that the women who used birth control pills, patches or rings including estrogen possessed 20% higher vitamin D levels in comparison to those who didn’t.

Harmon noted that they weren’t able to detect any behavioral differences, like spending more and more time outdoors, to describe the rise.

The investigators discovered that the women who stopped using such birth control methods possessed average vitamin D levels.

Harmon added their findings have suggested that contraceptives with estrogen in tend to push vitamin D levels, and such levels probably drop once women cease using contraception. Fatty fish and fortified milk are among the dietary sources of vitamin D.
