Can I do a ProLon cycle while I’m menstruating?
None of our trials so far have studied the impact of ProLon on menstrual cycles, nor have we studied the optimal time to fast regarding female hormone levels. You can do a ProLon fast at any time during your menstrual cycle. However, based on studies that others have done on the impact of water fasting on female hormones, it may be optimal to take ProLon mid-cycle, during the luteal phase.
