Nutrition, birth control pills and intrauterine device

Not so long ago, doctors prescribing oral contraceptives, at the same time prescribing 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, we know that the amount of hormones that is contained in birth control pills can only have a minimal effect on nutrition, notes nutritionist Bonnie Worthington-Roberts. A woman who has used contraceptive pills for many years may show signs of a deficiency in the body of vitamins C, B6 and B, but the probability of this is very small. "
However, if you use an intrauterine device to prevent pregnancy, there is a risk of iron deficiency. This is because the use of an intrauterine device often leads to an increase in the volume of menstrual flow and blood is lost iron. "Many women who prefer this type of contraception, for this reason, regularly use iron supplements," she says.
