Is this trial a fit for you?

Likely a good fit

Women age 18–40 with regular or mildly irregular cycles who in most of their past cycles had menstrual cramps rated ≥4/10, used OTC pain relief for at least two days per period, and who have had no changes in hormonal contraception in the past six months.

Probably not a fit

People outside the 18–40 age range, those without significant menstrual pain, those with major medical causes of pelvic pain, recent contraception changes, pregnancy, or lactation are unlikely to benefit from this trial.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a randomized, double‑blind, placebo‑controlled trial that assigns eligible participants equally to one of four arms (placebo, 100 mg Effera, 300 mg Effera, or two 100 mg doses daily) and follows them for 12 weeks of supplementation. Participants complete baseline assessments, then online questionnaires about menstrual symptoms, mood, gastrointestinal health, and quality of life roughly every four weeks, with an option to share wearable sleep and activity data. Randomization uses simple ABAB allocation with equal group sizes and all participants and study staff are blinded to assignment. Participants may stop at any time and the protocol targets otherwise healthy women with regular or mildly irregular cycles who experience moderate-to‑severe period pain.

Why it matters

Potential benefit: If successful, Effera could provide a nonprescription supplement option that lowers menstrual pain and improves mood and daily function for some women.

How similar studies have gone: Lactoferrin has some prior small studies suggesting anti‑inflammatory and gastrointestinal benefits, but using a human‑equivalent lactoferrin supplement specifically for menstrual pain and mood is relatively novel and not well established.
