What this trial studies

This is a 12-week, randomized, placebo-controlled trial in which participants take either a probiotic blend capsule or matching placebo daily. All study visits are conducted virtually, including symptom questionnaires and remote reporting, while blood samples are collected at baseline and follow-up to measure metabolic and inflammatory markers. Eligible participants report irregular menstrual cycles for at least six months and at least one hormone-related concern and must not be using hormonal therapies, metformin, GLP-1 agonists, or anti-androgens. Participants taking menstrual/hormonal supplements must stop them for a two-week washout before baseline and remain weight-stable during the study.

Who should consider this trial

Good fit: Women with self-reported irregular menstrual cycles and one or more hormone-related concerns (such as skin issues, unwanted hair growth, hair thinning, or weight concerns) who are not currently using the excluded medications are the intended participants.

Not a fit: Individuals currently on hormonal therapies, metformin, GLP-1 receptor agonists, or anti-androgens, or those unwilling to stop supporting supplements for the washout or provide required blood samples, are unlikely to benefit or be eligible.

Why it matters

Potential benefit: If successful, the probiotic could provide a low-risk daily supplement option to reduce inflammation, improve metabolic measures, and relieve some hormone-related symptoms for some women.

How similar studies have performed: Some small trials have shown modest metabolic or inflammatory benefits from specific probiotic formulations, but evidence directly supporting probiotics for menstrual irregularity and related hormone symptoms remains limited.
