Cleaning Is Essential. But It Doesn't Address The Real Issue.
Cleaning remains the foundation of oral care. It helps remove plaque, food debris and surface buildup. OMC-1 does not replace that first step. It adds a second one: dedicated support for the oral microbiome and the changing environment inside your mouth.
MICROBIOME SUPPORT WITH OMC-1
You Don’t Need to Replace Your Routine. You Need to Complete It.
Remove plaque, food debris and buildup from the mouth.
Add daily support for the oral microbiome after cleaning for microbial balance.
True Oral Health, Starting at the Source. Feel the OMC-1 Difference.
OMC-1 is designed to support the oral environment behind the everyday signals you actually notice, instead of just masking the symptoms temporarily.
Stronger, Healthier Teeth
By helping support a more balanced oral pH and the conditions that influence acid-producing bacteria, OMC-1 helps create an environment that supports natural enamel maintenance.
OMC-1 also contains hydroxyapatite — a mineral naturally found in tooth enamel. Rather than simply relying on temporary surface-level colour correction, hydroxyapatite supports the mineral tooth surface itself — helping support natural brightness and long-term tooth integrity.
Fresher Breath, Naturally
Breath freshness is often influenced by volatile sulphur compounds produced by certain oral bacteria. OMC-1 is designed to support a more balanced oral microbiome and the conditions associated with their formation — supporting fresher breath rather than simply masking it with flavour.
Healthier Gums
The bacteria living around the gumline interact directly with the tissues surrounding your teeth. When the oral microbiome shifts out of balance, plaque-associated bacterial activity can become more dominant in this area.
By supporting a more balanced oral microbiome, OMC-1 helps maintain healthier conditions around the gumline — supporting gums that look and feel healthy and a stronger foundation for your long-term oral-care routine.
Reduced Tongue Coating
Tongue coating is made up of microorganisms, proteins, dead cells and food debris that collect across the textured surface of the tongue.
By supporting a more balanced oral microbiome and healthier conditions inside the mouth, OMC-1 is designed to make the oral environment less supportive of excessive microbial buildup — helping the tongue maintain a cleaner, fresher appearance between cleaning.
Fresh Mouth Feeling
Supports an oral environment that feels fresher and more cared for throughout the day.
Helps support that clean, cared-for feeling between your regular brushing sessions.
Confidence in Your Smile
Your smile is part of how you recognise yourself. When your mouth feels fresh, healthy and cared for, you can spend less time checking what might be changing and more time simply feeling comfortable in your smile.
OMC-1 gives you a simple way to keep supporting that part of yourself as your oral-care needs evolve — helping you feel confident, feminine and like yourself when you smile.
OMC-1 is designed to support everyday oral wellness. Individual experience varies. Ingredient research should not be interpreted as a clinical trial of the finished OMC-1 product.
Your OMC-1 Journey: What To Expect
- Wake up with a fresher-feeling mouth after your nighttime routine.
- OMC-1 becomes an easy final step after brushing and flossing.
- Freshness feels more consistent between your morning and nighttime brushing.
- You spend less time thinking about or checking how your mouth feels during the day.
- Your mouth feels consistently cleaner and more cared for from one routine to the next.
- Daily oral microbiome support is now built into the routine you already trust.
- OMC-1 feels like an automatic part of your nighttime oral-care routine.
- You feel more confident knowing your routine now supports the oral microbiome as well as cleaning your teeth.
How long do I need to take it for?
OMC-1 is designed for ongoing daily use, just like any other supplement.
We recommend using it consistently for at least 90 days to give your oral microbiome time to adjust and for changes to build gradually.
For continued support, simply keep taking OMC-1 as part of your daily oral-care routine.
Individual experience varies. This timeline is not a guaranteed progression and is not based on a clinical trial of the finished OMC-1 product.

Your mouth isn’t just a surface to clean. It’s a living ecosystem made up of hundreds of different microorganisms competing for space, nutrients and access to oral surfaces.
Microbiome support means helping create and maintain the conditions in which that microbial community can remain balanced — rather than simply trying to remove as much bacteria as possible.
Traditional oral care is extremely important for removing plaque, food debris and surface buildup. But cleaning the mouth and supporting the ecology of the microbiome are not the same thing.
That is the gap ÓSTA was created to address.
ÓSTA means “host” in Irish — a reflection of the idea that your mouth is the host environment in which the oral microbiome lives.
OMC-1 is designed to support that environment through our Tri-Phasic Ecosystem Modulation™ system — Condition, Seed and Stabilize.
It doesn’t replace cleaning. It supports the living ecosystem that cleaning alone isn’t designed to manage.
You do not need to wait until your mouth feels dramatically different before thinking about the oral microbiome.
For many women, the appeal of microbiome-first oral care is proactive: supporting the oral environment as their biological needs evolve rather than waiting for a major problem to appear.
OMC-1 is designed as a daily wellness routine, not as a treatment for an oral disease.
No. It is a one-time purchase.
There is no automatic renewal and no recurring charge.
If you choose the 90-day option, you pay $118 once and receive the 90-day supply.
One payment. No subscription. No auto-renewal.
Orders typically arrive in around 5 days, although delivery can take up to 8 days.
OMC-1 purchases are covered by our 90-day satisfaction guarantee, subject to the terms of our refund policy.
It’s designed to give you enough time to actually incorporate OMC-1 into your daily routine rather than feeling like you need to make a decision after only a few uses.
No. Standard shipping applies to the $59 30-day supply.
Free U.S. shipping applies to the 90-day offer because the order value is above $100.
Everything Your Mouth Needs,
In One Daily Bite.
OMC-1 is built around our Tri-Phasic Ecosystem Modulation™ system - a three-stage approach designed to address the key conditions involved in supporting a stable oral ecosystem:
Reduce the Existing Ecological Advantage
Introduce Beneficial Strains Directly Into the Mouth
Support the Wider Oral Ecosystem
Unlike fermentable sugars, xylitol cannot be efficiently converted into acid by many plaque-associated bacteria. In xylitol-sensitive bacteria, repeated uptake can also create a metabolically wasteful cycle — helping reduce the energetic advantage of acid-producing species without trying to sterilise the mouth.
Guava fruit supplies naturally occurring polyphenols and other plant compounds that become part of the chemical environment surrounding the oral microbiome. Rather than adding bacteria, its role is to complement the conditioning phase before the probiotic strains are introduced.
Beta-cyclodextrin is a ring-shaped molecule with a water-compatible exterior and a relatively hydrophobic central cavity. That cavity can temporarily encapsulate certain small hydrophobic and volatile molecules, changing how they are dispersed and carried within the saliva-rich oral environment.
LS97 introduces a live Lactobacillus population directly into an already occupied microbial ecosystem. Its role is ecological: beneficial organisms compete with neighbouring microbes for nutrients, available space and access to oral surfaces — adding competitive pressure rather than attempting to eliminate the existing microbiome.
LC86 adds a second live probiotic population to that competitive environment. Because microbial communities are shaped by interactions between many organisms, introducing multiple species broadens the probiotic input across different microbial relationships, nutrients and potential surface interactions.
LA85 completes the three-strain probiotic component, adding another live microbial population rather than relying on a single organism. Together, the three strains increase the diversity of beneficial competitors being introduced into the oral ecosystem each day.
Hydroxyapatite is the calcium-phosphate mineral that makes up most of natural tooth enamel. Microcrystalline particles can deposit onto the enamel surface and into microscopic irregularities, providing mineral material that supports remineralisation and helps reinforce the physical tooth surface.

Everything You Might Still Be Wondering About OMC-1.
OMC-1 is designed to make microbiome-first oral care simple. Here are the answers to the questions women most often have before adding it to their routine.
Perimenopause and menopause involve changes in estrogen and other biological factors that can influence saliva, oral tissues, gum health and the environment inside the mouth.
Because the oral microbiome lives inside that environment, changes to the “terrain” can also influence the conditions in which different microorganisms compete and thrive.
That does not mean every woman will experience the same oral changes. It does mean menopause can be an important part of the picture that many women were never taught to consider.
OMC-1 includes three probiotic strains, but the formulation was designed around more than simply adding beneficial bacteria.
Its Tri-Phasic Ecosystem Modulation™ approach considers three complementary parts of oral microbiome support:
- Condition — support the oral environment.
- Seed — introduce beneficial probiotic strains.
- Stabilize — support the tooth surface and wider oral environment.
The idea is simple: bacteria do not act in a vacuum. The environment they enter matters too.
No.
Your existing cleaning routine and regular professional dental care remain the foundation of good oral hygiene.
OMC-1 is designed to add a microbiome-support step after that foundation — not replace it.
Take one OMC-1 chewable as the final step in your nighttime oral-care routine.
Slowly chew it and allow it to dissolve across the teeth, gums and tongue rather than treating it like a tablet that needs to be swallowed immediately.
The goal is to make it an easy final step in a routine you already perform every day.
You do not need to wait until your mouth feels dramatically different before thinking about the oral microbiome.
For many women, the appeal of microbiome-first oral care is proactive: supporting the oral environment as their biological needs evolve rather than waiting for a major problem to appear.
OMC-1 is designed as a daily wellness routine, not as a treatment for an oral disease.
Individual experiences vary.
OMC-1 is designed to be used consistently as part of an ongoing oral-care routine rather than as a one-time quick fix.
That is one reason the 90-day option is the recommended starting choice: it gives you enough time to make the routine habitual instead of judging a daily wellness practice after only a handful of uses.
The 90-day option gives you three bottles of OMC-1 for $118 instead of $177.
That means you save $59 — effectively making your first bottle free.
Because the order is over $100, it also qualifies for free U.S. shipping.
No. It is a one-time purchase.
There is no automatic renewal and no recurring charge.
If you choose the 90-day option, you pay $118 once and receive the 90-day supply.
No. Standard shipping applies to the $59 30-day supply.
Free U.S. shipping applies to the 90-day offer because the order value is above $100.
OMC-1 purchases are covered by ÓSTA's current 90-day satisfaction guarantee, subject to the terms of the refund policy.
This is designed to give you time to actually incorporate the product into your routine rather than feeling as though you have to make a decision immediately.
OMC-1 is not intended to diagnose, treat or replace professional care for dental or periodontal disease.
Persistent bleeding, significant pain, swelling, loose teeth or other concerning symptoms should be assessed by a dentist or appropriate healthcare professional.
Think of OMC-1 as a daily oral-wellness support step, not a substitute for clinical care.
