简要总结
The goal of this clinical trial is to learn if a human equivalent lactoferrin supplement (effera®) can improve menstrual symptoms, mood, and quality of life in healthy women aged 18-40.
The main questions it aims to answer are:
Does effera® reduce the severity of menstrual symptoms?
Does effera® improve mood, gastrointestinal symptoms, and overall well-being?
Researchers will compare three different doses of effera® to a placebo (a look-alike supplement with no active ingredient) to see if the supplement improves these outcomes.
Participants will:
Take the assigned supplement (effera® or placebo) daily for 12 weeks
Complete online questionnaires about menstrual symptoms, mood, and health
Optionally share sleep and activity data from a wearable device
详细描述
Explanation of Study Design This study will be completed as a randomized, double-blind, placebo-controlled investigation with all eligible participants being randomized in an equal allocation (1:1:1:1) to each of the four study groups. Upon screening and providing consent, each study participant will complete baseline assessments and be randomized into one of four groups. Each participant will take their assigned supplement each day for 12 weeks. Approximately every four weeks participants will complete a series of questionnaires intended to evaluate menstrual symptoms, quality of life, gastrointestinal symptoms, health, and more specific menstrual symptoms specifically aligned around their menstrual cycle. Participants are allowed to stop their participation or withdraw at any time.
Supplementation Groups Placebo Effera300 (1 daily dose of 300 mg) Effera100 (1 daily dose of 100 mg) Effera2x100 (2 daily doses of 200 mg)
Participants will be randomized to one of the four arms of the study using simple randomization (ABAB) and an even allocation ratio (1:1:1:1).

Change in menstrual symptoms (MSQ-24 score)
时间窗: Baseline, Week 4, Week 8, and Week 12
Menstrual symptoms will be assessed using the validated 24-item Menstrual Symptoms Questionnaire (MSQ-24), which measures the severity and frequency of physical, emotional, and behavioral symptoms associated with the menstrual cycle. Each item will be presented as a 5-level Likert scale (1=Never; 2=Rarely; 3=Sometimes; 4=Often; 5=Always). Higher scores indicate greater symptom burden.

- Change in psychological distress (PHQ-4)(Weekly from Baseline through Week 12)
- Change in gastrointestinal symptoms (PROMIS-GI Short Form)(Baseline, Week 4, Week 8, and Week 12)
