Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in Menstrual Symptoms Questionnaire (MSQ) Scores
Time Frame: Baseline, Menstrual Cycle 1, Menstrual Cycle 2, Menstrual Cycle 3 (each measured 2 days following menstruation)
Change from baseline in menstrual symptom severity as measured by the validated 24-item Menstrual Symptoms Questionnaire (MSQ). Rated on a 5-point Likert scale (Never, Rarely, Sometimes, Often, Always). Higher scores indicate greater symptom severity.
Baseline, Menstrual Cycle 1, Menstrual Cycle 2, Menstrual Cycle 3 (each measured 2 days following menstruation)

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Symptom Severity Ratings
Time Frame: Baseline, Menstrual Cycle 1, Menstrual Cycle 2, Menstrual Cycle 3 (each measured 2 days following menstruation)
Self-report rating of the severity of 13 common menstrual cycle-related symptoms experienced during their most recent menstrual cycle. Each item is scored on a 5-point Likert scale (Not noticeable, Barely noticeable, Moderate, Distracting, Severe). The questionnaire assesses 7 physical symptoms (fatigue, bloating, breast tenderness, headaches, cramps, body aches, food cravings) and 6 psychological symptoms (anxiety, irritability, mood swings, crying spells, concentration difficulties, low mood). Higher scores indicate greater symptom severity.
Baseline, Menstrual Cycle 1, Menstrual Cycle 2, Menstrual Cycle 3 (each measured 2 days following menstruation)
Proportion of participants with perceived reduction in menstrual cycle symptoms
Time Frame: Baseline, Menstrual Cycle 1, Menstrual Cycle 2, Menstrual Cycle 3 (each measured 2 days following menstruation)

Participants are asked how much they agree or disagree with 18 statements about the test product reducing symptoms, for example: "The test product reduces the severity of my menstrual symptoms", "The test product reduces the duration of my menstrual symptoms", "The test product reduces the amount of mood swings I have related to my period", "The test product reduces my menstrual cramps".

Response options: Strongly agree, Agree, Neither agree or disagree, Disagree, Strongly disagree
