WHAT THIS DOES FOR YOU
Targeted support, delivered
exactly where it's needed
An oral probiotic supports your gut. A vaginal probiotic supports the environment that matters most for reproductive health — directly, locally, and with the specific strains your microbiome actually needs.
The exact two strains recommended for restoring the vaginal and uterine microbiome
The right strains
We use L. rhamnosus and L. gasseri in our supositories, the two strains specifically recommended by Igenomix, the global leader in reproductive genetics and endometrial microbiome testing. These are the strains that matter for the vaginal and uterine environment, chosen by the clinicians who study it most closely.
Strain specificity matters enormously in probiotic science. Not all Lactobacillus strains do the same thing — and in reproductive health, the right strains are the difference between effective support and a product that simply doesn't work.
Supports the microbiome profile associated with favorable fertility and pregnancy outcomes
Fertility + Pregnancy
The vaginal and uterine microbiome play a meaningful role in implantation, early pregnancy, and reproductive outcomes. A Lactobacillus-dominant vaginal microbiome is consistently associated with more favorable fertility and pregnancy results in the clinical literature. These suppositories support that microbiome profile locally, directly, and with the strains that research points to most strongly.
Many fertility clinics now recommend vaginal probiotic support as part of pre-transfer protocols. These suppositories are formulated with exactly that clinical context in mind.
Supports balanced vaginal PH
PH Support
Antibiotics, among other causes, can disrupt the vaginal microbiome and pH balance. These suppositories help restore and maintain the Lactobacillus-dominant environment your body naturally supports, and prevent BV and yeast infections.
Applicator-free capsule - no mess, no additives
Clean Formula
No applicator, no parabens, no glycerin, no artificial fragrance. Just the strains, in a dissolvable capsule that's as simple to use as it is effective.
Clean ingredient standard: no artificial fragrances, no parabens, no glycerin, no unnecessary fillers. Made in a US FDA-registered facility.
Nurse Suzie & PA-C Andi
"When I was going through infertility, we learned that my vaginal microbiome did not contain some of the lactobacillus strains it needs to be healthy for pregnancy. I started using compounded vaginal probiotic suppositories, and they worked. Now we're making them accessible for everyone."

TRIPLE-TESTED QUALITY
Raw material tested. In-batch tested. 3rd-party tested for purity and potency. Every single batch.
GUIDELINE-FORMULATED
Every dose calibrated to ACOG, ASRM, and WHO recommendations — not marketing targets.
What's Inside Every Serving
The ingredients we chose, why we chose them, and what the clinical evidence actually says.
INGREDIENT Highlight 01
L. Crispatus
10 Billion CFU
WHY IT'S IN HERE
The dominant strain in a healthy vaginal microbiome. Clinically shown to reduce BV recurrence, support cervical mucus quality, and protect the vaginal ecosystem during fertility treatments.
The clinical evidence for L. crispatus is the strongest of any vaginal probiotic strain. We include it at therapeutic dose, not a token amount.
Ingredient highlight 02
L. Rhamnosus
5 Billion CFU
WHY IT'S IN HERE
Supports vaginal pH balance and reduces inflammatory markers associated with poor IVF outcomes. Works synergistically with L. crispatus to restore and maintain a Lactobacillus-dominant microbiome.
Selected specifically for its combination of evidence in both vaginal health and fertility outcomes.
HOW TO USE
Simple. Consistent. Effective.
One suppository
Insert one veggie capsule vaginally. No applicator needed. The capsule dissolves on its own.
At bedtime, every day
Take at bedtime for best results — lying down after insertion gives the probiotic strains time to establish.
As directed by your provider
Many protocols use 14 consecutive days. Always follow your individual provider's guidance.
WHAT TO EXPECT
Give it 30 Days
Establishing
Vaginal pH begins to shift as Lactobacillus strains start to establish. Many women notice reduced irritation and improved comfort within the first two weeks.
Stabilizing
Microbiome composition continues to stabilize toward a Lactobacillus-dominant environment.
Maintained
Use as needed to maintain a healthy vaginal PH and microbiome environment.

Everything you need to know about our Vaginial Probiotic Suppositories
Oral probiotics don't reliably colonize the vaginal microbiome. The vaginal route delivers the organisms directly where they're needed, at therapeutic concentrations, without the attrition of the GI tract.
Vaginal probiotics are most commonly used during fertility treatment cycles, after antibiotic use, or as ongoing maintenance for women with a history of BV or yeast infections. Our providers can give you personalized guidance.
Yes, this is formulated to the same standard used in clinical IVF protocols. Always inform your RE you're using it.
One suppository vaginally at bedtime, as directed. Refrigerate after opening.
BUILD YOUR FULL SYSTEM
Local support is one layer
Here's the full picture.
The Vaginal Probiotic supports the microbiome locally. These are what our clinicians most often recommend alongside it for a complete reproductive health protocol.
✓ LOCAL + SYSTEMIC SUPPORT
Reset Synbiotic
The first synbiotic formulated for fertility and pregnancy - 13 strains targeting gut, uterine, and vaginal health orally.
Why pair it: The Vaginal Probiotic works locally. Reset works systemically, supporting the gut-to-vaginal microbiome axis from the inside. Together, they address microbiome health at both levels simultaneously, which is how our clinicians approach it in practice.
✓ COMPLETE FERTILITY SUPPORT
Fertility Kit
Prenatal multivitamin + CoQ10 + NAC + Omega 3 - the egg quality and nutritional foundation for conception.
Why pair it: The Vaginal Probiotic optimizes the microbiome environment. The Fertility Kit optimizes egg quality, antioxidant status, and nutritional readiness. If you're actively trying to conceive or preparing for IVF, these two together form the most complete protocol we offer.
✓ Pregnancy Support
Prenatal Kit
Complete multivitamin + Algae DHA + Reset Probiotic - everything your pregnancy needs in one daily packet.
Why pair it: If you're already pregnant or just got your positive, the Vaginal Probiotic pairs naturally with the Prenatal Kit, supporting the vaginal microbiome locally while the Kit covers your full nutritional and systemic probiotic needs throughout pregnancy.
