Lactoferrin for Vaginal Health Study

Join a 4-week randomized, double-blind research study on effera® for women with recurring vaginal odor.
See if you qualify

This 4-week study tests whether a daily dose of effera®, a bio-identical lactoferrin, helps support a balanced vaginal microbiome, and it is done fully at home. Your participation helps researchers learn whether a simple daily supplement can make a difference for recurring vaginal odor. There is no cost to join, and the supplement and test kits are provided.

About This Study

Fully at-home study
Everything happens from home, with surveys in the Alethios app and test kits delivered to you. No clinic visits are required.
Free supplement and test kits
There is no cost to join. The study provides your daily effera® supplement and two at-home microbiome test kits.
At-home microbiome testing
You will collect a simple vaginal swab with an at-home microbiome test kit at the start (Day 0) and end (Week 4) of the study.
Randomized, double-blind dosing
Each participant is randomly assigned a dose of effera®. Neither you nor the study team will know your dose during the study.

What's Involved

You will take one dose of effera® each day for 4 weeks and answer a short weekly survey (about 5 minutes) in the Alethios app, which also lets the study team check in on how you are doing. You will collect an at-home vaginal swab with a microbiome test kit at the start (Day 0) and end (Week 4) of the study. No clinic visits are required.

Complete Screening and Electronic Consent

Answer a short screening questionnaire to see if you qualify. If you do, review and sign the consent form electronically through the Alethios platform.

Complete Baseline Survey and First Microbiome Swab

On Day 0, complete your baseline survey in the Alethios app and collect your first vaginal swab with the at-home microbiome test kit. On Day 1, start taking your daily dose of effera®.

Take Your Daily Supplement and Answer Weekly Surveys

Take one supplement each day and complete a short weekly survey (about 5 minutes) in the Alethios app during Weeks 1 to 3.

Complete Final Swab and Survey at Week 4

At Week 4, collect your second vaginal swab with the at-home microbiome test kit and complete your final survey in the Alethios app. There is no cash payment; your supplement and both test kits are provided at no cost.

What's Being Studied?

Lactoferrin is a protein the body makes naturally, and it helps support healthy Lactobacillus levels in the vagina. Less is known about whether taking lactoferrin daily as a supplement helps restore that balance in women with recurring vaginal odor. This study tracks changes in the vaginal microbiome over 4 weeks using at-home tests at the start and end, along with weekly surveys, while participants take a randomly assigned dose of effera.
