About

The purpose of this study is to examine and compare the uptake of Yasmin (oral contraceptive containing drospirenone and ethinylestradiol) with or without levomefolate calcium (Metafolin, a registered vitamin supplement) in the body and to examine and compare the uptake of levomefolate calcium with or without Yasmin in the body, in healthy volunteers not using hormonal contraception.
