Supports Oral Microbiome Balance
A complete complex with three oral-specific probiotic strains that help support a more balanced oral microbiome — not just surface-level cleaning.
Clinically Studied Ingredients
Every active ingredient selected based on peer-reviewed research — chosen for its studied role in oral health and microbiome support.
Designed For the Oral Environment
A chewable format designed for the oral environment — helping reduce plaque buildup, support beneficial bacteria, and enamel remineralization.
Introducing OMC-1
A Complete Complex — Designed to Support a More Balanced Oral Microbiome
OMC-1 is designed to help shift the oral environment toward a more balanced relationship between beneficial and less favourable bacteria — focusing on the ecosystem itself rather than simply covering up surface-level concerns. A balanced oral microbiome plays an important role in long-term oral health.
By introducing beneficial strains such as L. salivarius and L. paracasei, OMC-1 is designed to work with the mouth’s natural microbial environment. These strains are studied for the compounds they produce and for how they interact with other oral bacteria — helping support a more stable and resilient ecosystem over time.
The mouth plays a central role in the body’s wider biological network. By supporting a more balanced oral environment, OMC-1 is designed to help maintain the conditions associated with the oral–systemic connection — starting at the source.
Oral Health Support
Real Oral Health,
Starting at the Source
By supporting oral microbiome balance, OMC-1 is designed to address the underlying environment behind common oral concerns — helping support fresher breath, stronger teeth, and healthier gums over time.
Stronger, Brighter Teeth
By helping support a more balanced oral pH and reducing the conditions that allow acid-producing bacteria to thrive, OMC-1 helps create an environment that supports natural enamel maintenance — contributing to improved 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 help reduce the conditions associated with their formation — supporting fresher breath rather than simply masking it.
Healthier Gums
By helping shift the oral environment away from imbalance, OMC-1 supports a healthier gum environment and contributes to a more stable foundation for long-term oral health.

As that imbalance is addressed, the downstream effects can begin to shift.
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.

Everything Your Mouth Needs,
In One Daily Bite
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.
