A chewable format designed for the oral environment — helping reduce plaque buildup, support beneficial bacteria, and enamel remineralization.
Your Mouth Is The Gateway to Your Internal Ecosystem
There's now a growing body of published research behind the connection between your oral health and your broader health.
Large-scale UK Biobank research involving 500,612 adults found that signs of gum disease were independently associated with higher odds of living with multiple chronic health conditions — even after researchers accounted for factors including age, smoking, body weight and other shared risk factors.

The mouth is connected to the rest of the body through the bloodstream, immune system and digestive tract.
Inflamed gums can allow oral bacteria, microbial by-products and inflammatory signals into circulation, while saliva carries oral microbes into the gut every day.
Research Details
The analysis examined data from 500,612 UK Biobank participants. Researchers assessed self-reported signs of gum disease — including bleeding, painful or loose gums and teeth — and compared them with the presence of multiple chronic health conditions. The association remained after adjustment for major shared risk factors.

Why Oral Health Matters Beyond the Mouth
Research continues to reveal how the mouth is connected to systems throughout the body. From the gut and immune system to cardiovascular and cognitive health, the oral microbiome plays a far bigger role than most people realise.
Research continues to reveal how the mouth is connected to systems throughout the body. From the gut and immune system to cardiovascular and cognitive health, the oral microbiome plays a far bigger role than most people realise.
Inflamed gums can allow oral bacteria, bacterial by-products and inflammatory signals to enter the bloodstream. These can affect vascular health, activate immune pathways and contribute to inflammatory activity linked with the brain. This mouth-to-bloodstream-to-brain pathway is one reason oral health is increasingly studied in relation to memory, cognitive function and long-term neurological health.
Inflamed gums can allow oral bacteria and inflammatory compounds into the bloodstream. These can affect the inner lining of blood vessels, increase vascular inflammation and contribute to the biological processes associated with arterial plaque buildup.
The mouth is the first microbial environment in the digestive tract. Saliva carries billions of oral microbes into the gut every day, where they interact with the intestinal microbiome. When the oral ecosystem becomes imbalanced, greater numbers of unwanted oral bacteria can reach the digestive system and influence the wider microbial environment.
The oral microbiome is in constant communication with the immune system. A balanced oral environment helps maintain a healthy immune response, while persistent microbial imbalance can place greater demand on the body's defences.
Oral and metabolic health influence one another. Gum inflammation, microbial imbalance and metabolic health are connected through shared inflammatory pathways, making oral health an important part of the wider metabolic picture.
The mouth can be a significant source of ongoing inflammatory activity. When the gums and oral microbiome are out of balance, inflammatory signals can extend beyond the mouth and contribute to the body's overall inflammatory burden.
These connections make it clear that oral health is not isolated from the rest of the body. Supporting a healthy oral environment is part of a more complete approach to whole-body wellness.
Modern Living Strips the Oral Microbiome of Its Natural Defences
The scale of the problem can be seen in rates of gum disease.
Between highly processed diets and frequent exposure to harsh antibacterial oral-care products, everyday habits can deplete beneficial oral bacteria—leaving the oral ecosystem vulnerable and creating conditions for unwanted species to gain ground.
The Worst Part?
Most People Don't Even Notice The Symptoms
Sources: CDC/NHANES periodontal-health analyses and Luo et al., “Self-awareness of ‘Gum Disease’ Among U.S. Adults.” Prevalence estimates apply to adults with one or more natural teeth.
The Antibacterial Rebound Cycle
Harsh, antibacterial products are designed to kill bacteria broadly rather than distinguish between beneficial and unwanted species. They may create an immediate feeling of cleanliness and freshness, but temporarily lowering bacterial numbers does not correct the conditions that allowed unwanted species to thrive in the first place.
By repeatedly disrupting the bacteria that help maintain balance, harsh antiseptic routines can leave the oral ecosystem less resilient—and create conditions for unwanted species to regain ground easier.
Without supporting the conditions beneficial species need to thrive, the original problem returns, another rinse feels necessary, and the wipeout-and-rebound cycle begins again.
Your Mouth Should Act As Your Own Personal Guardian
Your Mouth Should Be Its Own First Line of Defence.
The oral microbiome is a living ecosystem where beneficial bacteria help maintain balance, support healthy teeth and gums, and keep unwanted species from gaining ground.
Caring for that ecosystem is an important part of a more complete approach to whole-body wellness.

Introducing OMC-1
A Complete Oral Microbiome Complex — Designed to Help Restore Microbial Balance.
OMC-1 is designed to help shift the oral environment toward a more balanced relationship between beneficial and less desirable bacteria—focusing on the ecosystem itself rather than simply masking surface-level concerns. A balanced oral microbiome plays an important role in long-term oral health.
With beneficial strains including L. salivarius and L. paracasei, OMC-1 is designed to work with the mouth’s natural microbial environment. These strains have been studied for the compounds they produce and their interactions with other oral bacteria, which is why they are included to support a more stable and resilient oral ecosystem over time.
The mouth is closely connected with wider biological systems through circulation, immune signalling and the digestive tract. OMC-1 keeps its direct focus where it belongs: supporting a balanced oral environment as part of a more complete approach to everyday wellness.

Oral Health Support
True Oral Health,
Starting at the Source
By supporting a healthier oral microbiome, OMC-1 is designed to address the underlying environment behind common oral concerns.
Supports Strong, Healthy Teeth
With hydroxyapatite and xylitol, OMC-1 is formulated to support the conditions associated with healthy enamel and everyday tooth mineral maintenance—complementing regular brushing and professional dental care.
Fresher Breath, Naturally
Bad breath is mostly caused by volatile sulphur compounds produced by certain oral bacteria. By supporting microbial balance, OMC-1 is designed to make the oral environment less favourable for these odour-producing bacteria—helping support fresher breath at the source rather than temporarily masking it with mint flavouring.
Supports Healthy Gums
By supporting a balanced oral environment, OMC-1 helps maintain healthy gums and a stable foundation for long-term oral health.
The OMC-1 Difference
Not Just an Oral Probiotic
Many oral probiotics simply introduce beneficial strains into an environment still dominated by harmful bacteria and structurally favourable to their return. Without addressing those conditions first, meaningful colonization becomes difficult to sustain.
Tri-Phasic Ecosystem Modulation™
Tri-Phasic System Designed to Support Colonization, Not Just Delivery
OMC-1 is built around our Tri-Phasic Ecosystem Modulation system—a three-part approach designed to address the key conditions involved in supporting a stable oral ecosystem:
Unlike harsh antibacterial products that broadly reduce beneficial and unwanted bacteria alike, OMC-1 uses xylitol and guava fruit powder to place targeted pressure on certain harmful oral bacteria.
Xylitol is taken up by susceptible bacteria but cannot be efficiently metabolized, forcing them to expend energy without gaining it. Guava fruit powder provides tannins and flavonoids studied for their ability to disrupt unwanted oral bacteria—helping them lose ground without treating the entire oral microbiome as something to sterilize.
Three oral probiotic strains are introduced into this prepared environment, where they can better adhere to oral surfaces, compete for space and nutrients, and contribute to a more balanced microbial ecosystem.
Microcrystalline hydroxyapatite supports enamel remineralization and helps create smoother tooth surfaces, helping reduce the structural niches where unwanted bacteria can adhere and persist.
Support Whole-Body Wellness Starting With Your Oral Microbiome
Finally… Oral Care As It Should Be
Rather than killing bacteria indiscriminately, OMC-1 helps suppress harmful species while supporting the beneficial bacteria your mouth actually needs.

Antibacterial oral care keeps your mouth clean.

Everything Your Mouth Needs,
In One Daily Bite
_a0743696.webp)
Every ingredient in OMC-1 was selected based on peer-reviewed research and given a defined role within our Tri-Phasic system—designed to help reduce conditions that favour unwanted bacteria, introduce beneficial probiotic strains and support the oral surfaces they interact with.
Certain acid-producing oral bacteria absorb xylitol as though it were sugar but cannot metabolise it efficiently—forcing them to expend energy without gaining the fuel they need to thrive. This helps make the oral environment less favourable to certain unwanted species without relying on broad-spectrum antibacterial action.
Provides naturally occurring polyphenols and other plant compounds that complement OMC-1’s microbiome-conscious formulation. Used alongside xylitol, guava fruit powder helps support a balanced oral environment before the probiotic strains are introduced in Phase 2.
A ring-shaped molecule designed to bind with volatile sulphur compounds associated with oral odour — helping reduce their presence at a molecular level rather than simply masking them.
A strain naturally found in a balanced oral microbiome. Following Phase 1, LS97 is introduced to compete with odour-associated bacteria for space and resources — helping support a more stable and balanced microbial environment over time.
Interacts with other bacteria in the oral environment and may help limit their ability to adhere to tooth surfaces — reinforcing the environment shaped in Phase 1. Contributes to maintaining oral microbial balance as part of the broader microbiome system.
Complements LS97 and LC86 by broadening the probiotic component of the formula. Together, the three strains help support microbial competition and maintain a more balanced oral environment over time.
Hydroxyapatite is the primary mineral found naturally in tooth enamel. OMC-1 includes microcrystalline hydroxyapatite to support enamel surface integrity and help maintain smoother tooth surfaces that are less favourable for unwanted bacterial buildup.

Frequently Asked Questions
Oral microbiome changes can occur before noticeable symptoms appear.
Supporting balance early can help maintain a healthy oral environment over time.
OMC-1 is designed for both proactive care and ongoing maintenance.
Gut probiotics are formulated for the digestive tract, while oral probiotics are designed to interact with the mouth's environment.
OMC-1 includes strains selected for their ability to function effectively within the oral cavity.
Brushing and flossing are essential for removing plaque, food debris and buildup from the teeth and gums. But they are primarily mechanical cleaning methods—they do not introduce beneficial probiotic strains or directly address every factor that shapes the oral microbiome.
OMC-1 is designed to complement, not replace, daily brushing and flossing by supporting a more balanced oral environment.
Absolutely keep brushing and flossing. OMC-1 is designed to work alongside these essential hygiene habits, not replace them. Brushing and flossing remove plaque and food debris, helping create a cleaner oral environment for the probiotic strains and other ingredients in OMC-1.
Take OMC-1 after brushing at night so its ingredients remain in contact with the oral environment rather than being immediately brushed away.
Antiseptic mouthwash is different. Many antibacterial rinses are designed to reduce bacteria broadly rather than selectively, meaning they may reduce beneficial bacteria alongside unwanted species. Regularly suppressing both can work against a microbiome-supportive approach.
For that reason, we recommend avoiding routine use of broad-spectrum antiseptic mouthwash while taking OMC-1, or using it at a different time of day. However, do not stop using a mouthwash prescribed by your dentist or healthcare professional without speaking to them first.
Two reasons—value and consistency.
OMC-1 uses oral-specific probiotic strains and active ingredients that are more expensive to formulate than a basic supplement. Subscriptions give us more predictable recurring demand, allowing us to reduce the margin on each order and pass that saving on to you.
OMC-1 is also designed for consistent daily use. The subscription makes it easier to maintain your routine without having to remember to reorder, and you can pause or cancel at any time.
Yes. Anytime. Two clicks from your account dashboard. No emails, no phone calls, no hoops.
Oral microbiome research is an evolving field, and approaches can vary between practitioners.
OMC-1 reflects a newer perspective focused on supporting microbial balance alongside traditional care.
OMC-1 combines multiple approaches, including supporting beneficial bacteria and maintaining the oral environment.
This multi-faceted design is intended to work alongside daily hygiene habits.
Chewable tablets release the active ingredients directly into the oral cavity, where they can interact with the teeth, gums, tongue and wider oral environment before being swallowed.
A conventional capsule is swallowed whole and provides very limited direct exposure inside the mouth. The chewable format gives OMC-1’s probiotic strains and supporting ingredients more direct contact with the oral environment.
OMC-1 can generally be taken alongside many commonly used supplements. However, antimicrobial supplements may reduce probiotic viability when taken at the same time, so consider separating them from OMC-1.
Speak with your healthcare provider before use if you take prescription medication, use high-dose antimicrobial products, have a medical condition, or are pregnant or breastfeeding.
Chew one OMC-1 tablet slowly after brushing at night and allow it to dissolve throughout the mouth before swallowing.
Taking it after brushing allows the probiotic strains and supporting ingredients to remain in contact with the oral environment rather than being immediately brushed away.
Individual experiences vary. Some beta testers have reported noticing changes within the first few weeks, while others may require more consistent use over time.
OMC-1 is designed for regular daily use rather than as an immediate or one-time solution.
No. At the moment, we only ship domestically in the US.
OMC-1 is designed for ongoing daily use rather than as a short, one-time course. Like brushing, flossing and other oral-care habits, consistency helps maintain the environment the routine is designed to support.
Our subscription makes consistent use easier, but you can pause or cancel at any time.
Use at least 90 days’ worth of OMC-1 as directed, whether purchased as one 90-day supply or as three 30-day supplies. If you’re not satisfied after 90 days, you may request a refund of the eligible product purchase price between days 90 and 120 after delivery of your first qualifying order.
Shipping charges are non-refundable, and the guarantee is limited to one approved claim per customer. Refund requests submitted after day 120 are not eligible. See our full guarantee terms for details.
OMC-1 is formulated for adults. Consult a paediatrician or dentist before giving OMC-1 or any dietary supplement to a child.
The formula includes ingredients commonly used in oral care products designed to support enamel. If you have sensitivity concerns, it's best to check with your dentist.
OMC-1 contains xylitol and no added sugar. However, people with diabetes or any other medical condition should review the full ingredient list and consult their healthcare provider before use.
