An Exploratory Investigation of Dietary Supplementation and the Effect on Common PMS and Menstrual Symptoms

This is an open-label observational trial to study the effectiveness of a commercial dietary supplement and its effect on common symptoms of normal menstrual discomfort. It is hypothesized that the dietary supplement marketed as Semaine PMS \& Period Support will improve subjective wellbeing and biomarkers in trial participants. A total of 58 participants will be recruited for the trial following screening, with the expectation that at least 51 will complete the trial. The trial will be fully remote, and all participants will undergo a menstrual cycle without intervention to establish a baseline, and then will be given the intervention (dietary supplement) for a second menstrual cycle. For both menstrual cycles the participants will complete a subjective wellbeing survey and provide a blood sample for biomarker analysis. The biomarker analysis will be performed through an at-home fingerprick blood test. To maximize consistency, the tests should be performed on the same days of each cycle - preferably on days 4 or 5. If absolutely necessary, however one day of buffer on either side will be allowed.
