Nutrition, contraceptive pills and intrauterine device

Not so long ago, doctors, prescribing oral contraceptives, at the same time prescribed vitamins. It was believed that taking birth control pills increases the need for a number of nutrients, including vitamins C, B6 and folates (vitamin B).
“Today it is known that the amount of hormones contained in birth control pills can only minimally affect the nutritional processes, says nutritionist Bonnie Worthington-Roberts. A woman who has used birth control pills for many years may have signs of a lack of vitamins C, B6 and B, but this is very unlikely. ”
However, if you use an intrauterine device to prevent pregnancy, there is a risk of iron deficiency. This is due to the fact that the use of an intrauterine device often leads to an increase in the volume of menstrual flow and iron is lost with blood. "Many women who prefer this type of contraception, for this reason, use iron supplements regularly," she says.
