ZINNIA CATOX EZYME is a food product made from fruits and vegetables, and it does not have any negative effects on the menstrual cycle. However, some women may experience abdominal discomfort during their period, and when starting to take ZINNIA CATOX EZYME, may potentially cause stronger intestinal movements. If you don’t mind the possibility of increased intestinal activity, you can continue taking ZINNIA CATOX EZYME as usual during your menstrual period.
