DAILY IMMUNOTHERAPY
An allergy immunotherapy that fits the morning you already have. Once a day. Two minutes.
Built around your specific allergies. · $39 first month. 90-day money-back. Cancel anytime.
FSA/HSA eligibleTHE MECHANISM
Brush your teeth. Two minutes, once a day. Allergists have used these same allergen extracts in shots and drops for decades — but delivered through a toothpaste, they reach the densest concentration of immune cells in your body. Over six to twelve months, your immune system stops escalating. The brushing becomes the therapy.

Ritual is the active ingredient.

Before it was therapy, it was an idea at a bathroom sink.
INVENTED, THEN PROVEN
Allergen immunotherapy is decades old — the same mechanism behind shots and drops. The toothpaste vehicle is new, formulated by Dr. William Reisacher at Weill Cornell and proven through a decade of his peer-reviewed clinical work.

STILL DECIDING?
Twice a day, when you brush, the toothpaste holds tiny calibrated amounts of your specific allergens against the lining of your mouth. Over six to twelve months, your immune response gradually shifts from reactive to tolerant. Full mechanism at /science.
Most patients notice meaningful symptom reduction by month 6, with full immune-system retraining over a 12-month course. Some report earlier changes in months 2–3. Treatment is gradual by design — the same shift that shots and drops produce, just delivered on a daily route patients actually finish.
No. Your formula is custom-compounded to include all of your relevant airborne allergens in a single toothpaste. One tube, one routine — whether that's two allergens or eight.
Our adult course is for ages 18+. A pediatric track for ages 5+ is launching as a fast-follow — join the waitlist at /pediatric. Children under 5 are not eligible.
Mucosal-route immunotherapy more broadly has decades of safety data; the toothpaste vehicle is newer, with peer-reviewed safety data going back to 2014 and a 2025 Phase 1 trial of a related product that reported zero discontinuations due to side effects. Your formula is reviewed by a US-licensed allergy specialist. Full safety profile →
A US-licensed allergy specialist on our provider network reviews every formula before it's compounded. Your specific tube is then prepared by a state-licensed 503A compounding pharmacy under your prescriber's order.
If you don't see meaningful improvement in your first 90 days, we refund your treatment in full. No paperwork gauntlet.
Yes. You can pause shipments for up to six months from your portal, or cancel anytime — no calls, no retention scripts. Your 90-day money-back window remains open even after cancellation.
The allergen extracts in your formulation are FDA-listed. Your specific compounded toothpaste is prepared by a licensed 503A pharmacy under your prescriber's order. Compounded medications are regulated through the FDA's compounding pathway, not the FDA's approval pathway. Detail at /science and /safety.
Shots and drops are the same idea — gradually exposing your immune system to your specific allergens — but delivered through a needle in a clinic or under-the-tongue drops you take twice a day on top of everything else. Most people don't finish either course (26–38% for shots, 11.6% for drops). Easily integrates the dosing into brushing — once a day for two minutes, alongside your normal routine.
