Thank You For Your Interest In Our Vaginal Health Study

Are you experiencing a recurring odor that keeps coming back even when nothing else seems wrong?

You're not imagining it, and you're not the only one. It may be vaginal dysbiosis, a common imbalance in the vaginal microbiome, and we're studying whether a daily supplement can help correct it.

This study is:  No cost · Fully at-home · About 4 weeks · IRB-reviewed

Why vaginal odor happens

A healthy vaginal microbiome is dominated by Lactobacillus bacteria, which keep odor-causing bacteria in check. When Lactobacillus drops, other bacteria move in producing the compounds behind that recurring smell.

effera® is a human-equivalent lactoferrin, a protein your body already makes naturally to support healthy Lactobacillus levels. This study tests whether taking it daily can help restore that balance.

Study requirements

• Take a daily supplement (double-blind, randomly assigned dose)
• Complete an at-home microbiome test kit and swab at the start and end of the study
