Built for the woman living it — not an abstraction of her.

Menopause is not a chart or a checklist. It is mornings, work, intimacy, and everything in between. The Menopause Synbiotic was made for the whole of that life.

Let's normalize this upfront

Vaginal and gut health belong in the menopause conversation.

Menopause Synbiotic was built as the daily microbiome foundation of the SEASON34 system. It supports balanced vaginal flora, vaginal pH, vaginal hydration, elasticity, mucosal integrity, everyday freshness, digestive comfort, normal bowel regularity, and gut microbiome balance with one once-daily capsule.*

Proof you can actually understand.

The strongest story behind Menopause Synbiotic is a clinically studied probiotic blend, measured improvements across the markers that matter most for menopause, and a daily microbiome foundation built specifically for postmenopausal women.

Not a single-strain probiotic.

Pre + pro + postbiotic. In one daily capsule.

Most menopause probiotics ship one strain at a high CFU count and call it a day. Single strain. Single layer. No prebiotic to feed it. No postbiotic to back it up.

Menopause Synbiotic was built around all three layers — a prebiotic that feeds beneficial bacteria, a 3-strain live probiotic clinically studied in postmenopausal women, and a heat-killed postbiotic for immune-mucosal interaction. Delivered through an acid-resistant capsule designed to get the live strains and postbiotic past gastric acid intact.

Higher CFU is not automatically better and not all probiotics are created equal. The relevant question is whether the dose and strains have been clinically studied for the outcome you want.

What to expect

Microbiome restoration takes time. Daily use is how you give it that time.

Menopause Synbiotic is built on three layers of microbiome support — prebiotic fiber to feed beneficial bacteria, three live probiotic strains studied for vaginal flora support, and a heat-killed postbiotic for immune-mucosal interaction. The work happens daily. Here's what daily use actually looks like.

01
Day one

One capsule. With water. Done.

The whole routine is one capsule with breakfast — no probiotic refrigeration, no powders, no taking on an empty stomach. The BioVXR® acid-resistant capsule does the work of getting the live strains and postbiotic past gastric acid and into the intestinal target environment. Day one is just about starting.*

The capsule travels through stomach acid.
02
Day 14

The strains show up to work.

Fourteen days of daily use is when the SynbÆctive® Femme™ 3-strain blend has had real time to build a daily rhythm. The live strains have started doing what they're built to do — supporting balanced vaginal flora, vaginal pH, vaginal hydration, elasticity, and a Lactobacillus-dominated microbiome. Some women start to notice everyday freshness and vaginal comfort that feels more supported. Others need more time. Both are normal.*

Strains have populated. Daily rhythm builds.
03
Day 28

Four weeks in.

By now, daily use is just part of your morning. Four weeks of strains showing up, prebiotic feeding them, postbiotic working alongside. Some women describe everyday freshness, vaginal comfort, and a sense that the conversation has quieted down — less daily monitoring, more daily living. The 28-day window is also when the clinical research measured improvements across vaginal hydration, elasticity, fluid volume, mucosal integrity, and pH. Daily microbiome support that does its job in the background while you do yours in the foreground.*¶

VHI subcategories measured improvement.

Percentages and outcomes reflect published clinical research on standardized key ingredients in Menopause Synbiotic. Individual results vary based on baseline status, consistency of use, lifestyle, hormonal status, and whether products are used alone or as part of the SEASON34 system.

Inside the formula

Three branded actives. One daily capsule.

Each active was selected for a reason — and every dose is on the label. Menopause Synbiotic brings together three branded actives selected for vaginal flora and pH support, digestive comfort, gut microbiome balance, immune-mucosal interaction, and the broader microbiome shifts of menopause.*

01

SynbÆctive® Femme™ 3-strain probiotic blend.

Supports balanced vaginal flora, vaginal pH, vaginal hydration, elasticity, fluid volume, mucosal integrity, and a Lactobacillus-dominated vaginal microbiome.*¶

3 mg per serving · 3 billion cells per serving

FloraSMART® is heat-killed Lacticaseibacillus paracasei strain 327 from Japan. Cell-wall components and bioactive compounds support immune-mucosal interaction and daily digestive comfort.

Postbiotic layer
04

BioVXR® acid-resistant capsule (delivery).

Acid-resistant chemistry helps the live strains and postbiotic survive gastric acid and dissolve preferentially in the intestinal target environment.

Capsule technology

BioVXR® is a delivery technology, not an active ingredient.

Biology-based microbiome support

Not one-size-fits-all. Not a single-strain probiotic.

Menopause is universal. A woman's microbiome experience is not. SEASON34 was built around biology-based symptom areas, not generic wellness buckets.

Menopause Synbiotic focuses on the area where vaginal flora, pH, comfort, digestive balance, and gut microbiome support can overlap. Different layers. One smarter formula.

01

Vaginal flora, pH, hydration, and elasticity support.

The SynbÆctive® Femme™ 3-strain probiotic blend at 3 billion CFU daily supports balanced vaginal flora, vaginal pH, vaginal hydration, elasticity, fluid volume, mucosal integrity, and a Lactobacillus-dominated vaginal microbiome.*¶

02

Digestive comfort and bowel regularity.

FiberSMART® prebiotic fiber and FloraSMART® postbiotic support digestive comfort, normal bowel regularity, and gut microbiome balance.*‡

03

Immune-mucosal support.

The live probiotic blend and heat-killed postbiotic deliver bioactive cell components for immune-mucosal interaction through the gut microbiome.*

04

Gut-brain axis support.

Supports mental wellness through the gut-brain axis as part of daily microbiome support.*

More precise than one-size-fits-all

Targeted, not generic.

Most probiotics are generic gut formulas. SEASON34 was built differently, with targeted formulas designed around biology-based symptom clusters. Menopause Synbiotic is the foundational microbiome layer — vaginal flora and pH, digestive comfort, gut microbiome balance, immune-mucosal interaction, and the gut-brain axis.

Frequently asked

Questions, answered honestly.

What does Menopause Synbiotic support?

Menopause Synbiotic supports balanced vaginal flora, vaginal pH, vaginal hydration, elasticity, fluid volume, mucosal integrity, everyday freshness, digestive comfort, normal bowel regularity, gut microbiome balance, immune defenses through the gut microbiome, and mental wellness through the gut-brain axis.*

What makes Menopause Synbiotic different from a generic probiotic?

Menopause Synbiotic was built around three layers — a prebiotic, a clinically studied vaginal-flora probiotic blend, and a postbiotic — in one daily capsule. Most menopause probiotics deliver just one of the three layers. The SynbÆctive® Femme™ 3-strain probiotic blend at 3 billion CFU daily is the dose studied in postmenopausal women.*¶

Why 3 billion CFU? Other probiotics advertise higher counts.

Three billion CFU is the dose studied in the Vicariotto 2024 clinical trial on postmenopausal women aged 45–65. Higher CFU counts in other probiotic products are not automatically better — the relevant question is whether the dose has been clinically studied for the outcome you want. *¶

Why is Synbiotic built for menopause?

The vaginal microbiome, gut comfort, and microbiome shifts can all become more relevant during the menopausal transition. The SynbÆctive® Femme™ 3-strain probiotic blend was clinically studied in postmenopausal women aged 45–65. Menopause Synbiotic was designed specifically for this stage of life.*¶

How long should I use it?

Consistency matters. The supplier-recommended minimum daily-use window is 14 days, and the primary clinical research endpoint was measured at Day 28. Longer-term daily use supports the daily microbiome foundation.*

Does it need refrigeration?

No. Menopause Synbiotic uses the BioVXR® acid-resistant capsule, a plant-based delivery technology designed to protect the live strains and postbiotic at room temperature through the typical shelf-life window. Store cool and dry, out of direct sunlight.

Can I take it with other SEASON34 formulas?

Yes — Menopause Synbiotic is the foundational microbiome layer of the SEASON34 system. Every active is unique to this SKU and delivers its full per-serving dose with every capsule, regardless of what else you stack. Take the quiz to find the formulas that fit your symptom profile.*

Why do you disclose every ingredient dose?

Because you should know what you're taking. Many probiotic products use proprietary blends that disclose total CFU but not per-strain doses. Menopause Synbiotic discloses every active and every dose on the label — including 3 billion CFU of the SynbÆctive® Femme™ 3-strain blend (1 billion CFU per strain), 50 mg of FiberSMART® prebiotic fiber, and 3 mg / 3 billion cells of FloraSMART® postbiotic. Transparent doses on every label.*
