Carbohydrate oral-rinse science
The Science is called Rinsing. We built a pouch.
35+ studies have investigated carbohydrate mouth rinsing, with some time-trial studies reporting improvements of roughly 1–3% under specific conditions. Rinse is designed to deliver that stimulus — passively, hands-free, throughout your effort.

Smallest worthwhile change for elite athletes — the margin that wins races
Hopkins et al.
✓Works with repeated bursts
Serial administration within a session significantly improves performance. No receptor desensitization. Effect may increase as glycogen depletes.
✓No one-use ceiling
Published protocols use 8–10 discrete exposures per session. The polysaccharide receptor does not adapt like sweet taste receptors.
✓Validated in sport
Hockey players report wearing lip pouches throughout high-intensity play — noticeable but non-irritating. Same anatomical placement.
✓Patent pending
US Application No. 64/052,432, filed 29 April 2026. Novel application of oral pouch delivery to COR reflex stimulation in athletes.
How it works
Simple. Passive. Built from 20+ years of oral-rinse research.
01
Place
Tuck the pouch between your upper lip and gum before the start. Stays in place by anatomical compression — no adhesive needed. Same as caffeine pouches.
02
Activate
Saliva dissolves the first carbohydrate pocket, releasing a targeted dose into the oral cavity. Your carbohydrate receptors activate. Your brain responds.
03
Repeat
Every 15–20 minutes the next wax barrier erodes and the next pocket releases. Each burst is a fresh receptor event. No rinsing, no spitting, no stopping.
04
Finish
Caffeine releases gradually across your effort. Remove the pouch at the line. All materials food-safe and swallowable.

First-tin guarantee
If you don't feel it — it's free.
Try your first tin. If you notice no difference during training or competition, we'll refund it in full. No form, no questions.
Research suggests roughly 70–80% of trained athletes show a meaningful response. The remaining 20–30% have lower oral carbohydrate receptor sensitivity — a genetic individual difference, not a product failure.
Who Rinse is for
Trained cyclists, runners, and triathletes competing in efforts from 45 minutes to several hours. If you've ever felt a carbohydrate drink lower your effort perception mid-race — that's the reflex. Rinse delivers it passively, on a pouch.
Evidence is strongest in trained athletes in 45–90 minute high-intensity efforts, fasted or race-morning fuelling. Effect attenuated in recreational athletes in fed state.

We're putting the first tins in the hands of trained athletes for testing. Join the list and we'll reach out when they're ready.

The evidence base
The carbohydrate oral-rinse reflex.
Oral carbohydrate receptors — including a T1R-independent polysaccharide receptor distinct from sweet taste receptors — may influence brain regions tied to reward, effort, and motor control before meaningful digestion is required.
35+ randomised controlled trials have demonstrated this effect consistently across cycling and running time trials in trained athletes.

Key findings
What the research shows
01
Serial exposure works. Repeated carbohydrate mouth rinse administration within a single session significantly improves peak power output. Published protocols commonly use repeated carbohydrate exposures during exercise. Rinse is designed to mimic this repeated-signal approach.
02
The receptor doesn't desensitize. Carbohydrate (maltodextrin) activates a T1R-independent polysaccharide receptor, separate from sweet taste receptors. Unlike sugar receptors, this receptor does not show rapid adaptation. Each burst event is a fresh signal to the brain.
03
Effect strengthens with depletion. The COR reflex effect is actually enhanced under glycogen-depleted conditions — the greater the depletion, the more sensitive the oral receptors appear to be. This means the effect grows across a race as fatigue accumulates.
04
Strip format beats liquid rinse. A dissolvable oral strip produced 3.02% improvement in a running TT vs. 1.91% for standard liquid mouth rinse. Sustained mucosal contact is superior to bolus rinse-and-spit. This is the mechanistic basis for the Rinse pouch format.
05
Menthol enhances perception at trace levels. A 0.01% menthol coat in the flavour layer adds a clean, neutral mouthfeel without altering pharmacological effect. It signals freshness during exertion and improves pouch acceptability across long sessions.
06
Non-responders exist. Approximately 20–30% of athletes have lower oral carbohydrate receptor sensitivity and may experience little or no benefit. This is a genetic individual difference. This is why Rinse offers a full first-tin guarantee.
Marathon / Ironman athletes, fed state, 2–3+ hours. Use alongside normal race fueling.

The founder
Built by a student. Built on science.
I'm Harrison Landry, an exercise science student studying sport and human performance. I've spent the last year reviewing 40+ peer-reviewed studies on carbohydrate oral sensing, conducting an independent literature analysis, and developing the formulation concept — before filing a provisional patent in April 2026.
The mechanism is real. The performance benefit is consistent across 35+ randomised controlled trials. But every existing protocol requires athletes to carry rinse solutions, rinse and spit, and interrupt their race. Nobody has built a passive, hands-free delivery system for it.
Rinse is that product. A single-use oral pouch designed to deliver repeated carbohydrate exposure throughout a competition — without rinsing, without spitting, without stopping.
The product is patent pending. The science is peer-reviewed. The first tins are in development.

The mission
Science for every athlete.
The carbohydrate oral-rinse effect has been demonstrated in peer-reviewed literature since 2004. In twenty years, it has never been practically accessible to athletes during competition. Rinse changes that.
