Brief Summary

This clinical trial aimed to evaluate the effectiveness of a combination of Black Cohosh, Soy Isoflavones, and SDG Lignans compared to a placebo in reducing menopausal symptoms in postmenopausal women aged 45-60 years. The study was meticulously designed to be a randomized, double-blind, parallel-group trial, ensuring rigorous scientific standards and participant confidentiality. It received ethical approval and adhered to the Declaration of Helsinki guidelines. Participants were carefully selected based on specific inclusion and exclusion criteria to maintain the study's integrity and relevance to the target population. The trial involved 96 eligible women from the Center for New Medical Technologies registry in Novosibirsk, Russia, divided into two groups through a computer-generated random sequence. One group received the active supplements, while the other received a placebo, with both groups and researchers blinded to the assignments. The supplements and placebos were produced to be indistinguishable in appearance, with dosages designed to maximize absorption and efficacy while minimizing side effects. The primary endpoint was the change in Menopause Rating Scale (MRS) scores, with secondary outcomes focusing on adverse symptoms and key hormonal changes. The study's design also included measures to ensure adherence and minimize bias, such as drug container returns and daily reminders. The involvement of S.Lab (Soloways) was limited to manufacturing the supplements, with the research conducted independently to avoid commercial influence. The sample size calculation indicated that 48 participants per group would provide adequate power to detect significant differences in menopausal symptom reduction, aiming for a high level of confidence and statistical power.
