Brief Summary
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

Outcome Measures
Primary Outcomes (1)
Change in menstrual symptoms (MSQ-24 score)
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.
Baseline, Week 4, Week 8, and Week 12
Secondary Outcomes (4)
Change in global health (PROMIS Global Health-10)
Baseline, Week 4, Week 8, and Week 12
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
Change in menstrual cycle-specific symptoms
Baseline and monthly during the study (Weeks 4, 8, and 12)
Other Outcomes (1)
Sleep and physical activity metrics (wearable devices)
Continuously collected throughout the 12-week study period
Study Arms (4)
Arm 1: Placebo Comparator
PLACEBO COMPARATORParticipants receive a matched placebo supplement daily for 12 weeks.
Arm 2: Effera® 100 mg
ACTIVE COMPARATORParticipants receive 100 mg of effera® (human equivalent lactoferrin) once daily for 12 weeks.
Arm 3: Effera® 200 mg (Split Dose)
ACTIVE COMPARATORParticipants receive 200 mg of effera® daily, administered as two 100 mg doses, for 12 weeks
Arm 4: Effera® 300 mg
ACTIVE COMPARATORParticipants receive 300 mg of effera® once daily for 12 weeks.
Interventions
Matched placebo supplement identical in appearance and packaging to the active intervention, administered orally once daily for 12 weeks.
Effera® is a human equivalent lactoferrin supplement administered orally once daily at varying doses (100 mg, 200 mg, or 300 mg) depending on randomized assignment. Lactoferrin is a naturally occurring protein involved in immune regulation, iron metabolism, and inflammation.
Eligibility Criteria
You may qualify if:
- Participants must meet all of the following criteria to be eligible for participation:
- Women, 18 - 40 years of age
- No changes in hormonal contraception use in the past 6 months
- Regular or mildly irregular cycles (24-45 days) for the past 3 months
- In the majority (\>3) of menstrual cycles over the past 6 months, experience menstrual cramps on a pain scale of at least 4 out of 10 (1=no pain at all and 10 = worst pain ever experienced)
- In the majority (\>3) of menstrual cycles over the past 6 months, experience pain so significant that it requires over-the-counter pain medication for at least 2 days (on average) per period
- In the majority (\>3) of menstrual cycles over the past 6 months, experience at least one day per cycle where menstrual symptoms either interfere with work or school performance, limit normal daily activities or exercise, or lead to staying home, leaving early, or modifying plans
- Reports noticeable mood or physical changes in the 5-7 days before menses in most cycles (irritability, mood, bloating, breast tenderness, cravings, sleep changes, etc.)
- Generally healthy and free of diseases or disorders that impact functioning of the gastrointestinal system.
- No recent or acute infection in the past 30 days and no chronic systemic illness

- Body mass index (BMI) 18.5 to 32.5 kg/m2 (Inclusive)
- Non-smoker
