Can vitamin supplements cause your period to come a week early?

Answer 1

No, vitamin supplements cannot cause your period to come a week early - vitamin supplements are just vitamins, like what you'd consume with a healthy diet. Although Vitamin C in high doses can induce your period if it is due as it starves the uterus of progesterone.

Answer 2

Menstrual cycles vary from person to person, and there are many factors that can affect the timing of your period. Vitamin supplements are not known to cause your period to come early.
