What this trial studies

This multicentre, exploratory study aims to assess the efficacy of SE5-OH tablets, a food supplement containing S-equol, in reducing menopausal symptoms in healthy women aged 45-60. The study will involve up to 300 participants across 10 hospitals in Spain, with a recruitment period of 6 months. Participants will receive the tablets for 12 weeks, followed by a 4-week follow-up period to evaluate symptom changes. The study will ensure that all candidates meet specific inclusion criteria and will provide detailed information about the investigational product before participation.

Who should consider this trial

Good fit: Ideal candidates are healthy women aged 45-60 who have been experiencing moderate to severe menopausal symptoms for at least one month.

Not a fit: Patients currently receiving hormone replacement therapy or with certain severe health conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could offer a new non-hormonal treatment option for women experiencing menopausal symptoms.

How similar studies have performed: While this approach is exploratory, similar studies evaluating S-equol for menopausal symptoms have shown promise, suggesting potential for success.
