L. fermentum (Vaginal Health)
A probiotic strain that supports a healthy vaginal microbiome and helps prevent infections.
Also known as: Lactobacillus fermentum
Overview
Lactobacillus fermentum is a probiotic bacterium that is naturally found in the human body, including the vaginal tract. Specific strains of L. fermentum have been studied for their ability to inhibit the growth of pathogens that cause bacterial vaginosis (BV) and yeast infections, making it a valuable component of women's health supplements.
Key Benefits
Inhibits Pathogen Growth
L. fermentum produces antimicrobial compounds that can inhibit the growth of harmful bacteria and yeast, such as Gardnerella vaginalis and Candida albicans.
Supports a Healthy Vaginal pH
Like other lactobacilli, L. fermentum produces lactic acid, which helps maintain the acidic environment of the vagina that is protective against infections.
Contributes to a Balanced Microbiome
Supplementing with L. fermentum can help to restore and maintain a healthy balance of bacteria in the vaginal microbiome.
Dosage & How to Take
For vaginal health, L. fermentum is often included in probiotic blends with other Lactobacillus strains. The typical dosage is between 1-10 billion CFUs per day.
| Purpose | Dose | Notes |
|---|---|---|
| Daily Maintenance | 1-5 billion CFUs/day | As part of a probiotic blend for general vaginal wellness. |
| Support During or After Infection | 5-10 billion CFUs/day | A higher dose may be beneficial when trying to restore a healthy microbiome. |
Best Time to Take
Can be taken at any time of day.
