Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this study is to investigate the effect of pollen extracts on menopausal symptoms in healthy women The main question it aims to answer is:

What is the difference in change in severity of menopausal symptoms as assessed by the total Menopause Rating Scale (MRS) score from baseline at Week 36 between Graminex Water Soluble Pollen Extract (WSPE), Lipid Soluble Pollen Extract (LSPE), and Placebo?

Participants will be asked to complete the MRS assessment tool to rate their menopausal symptoms while receiving either WSPE, LSPE, or Placebo.
