The effect of preconceptional multivitamin supplementation on the menstrual cycle.
The database of the Hungarian randomised controlled trial of periconceptional multivitamin supplementation for the prevention of neural-tube defects was used to evaluate the length of the pre- and postovulatory phases of the menstrual cycle before and during multivitamin supplementation. The female cycle was more regular (i.e., the variance was lower) during the multivitamin supplementation.
