Breathe better at work —
without changing your routine
A lot of us mouth-breathe through the working day without realising it — especially at a desk, in meetings, or staring at screens. REMplenish turns your water bottle into a passive breathing trainer. Every sip strengthens the muscles that support nasal breathing, so the habit builds itself.
Nasal breathing training that fits your working day
The REMplenish Myo-Nozzle™ is a patented drinking nozzle that transforms everyday hydration into targeted tongue and throat training. Each sip activates the muscles that support nasal breathing — with no separate exercises, no routine changes, and no extra time out of your day.
- Strengthens the tongue and throat muscles that support nasal breathing
- Encourages correct oral rest posture throughout your day
- Reduces the mouth breathing that causes afternoon fatigue and brain fog
- Works with any compatible 8–10mm straw
- Available in Level 1 (gentle) and Level 2 (stronger resistance)
The Myo-Nozzle™ — passive training built into your bottle
Fit your Myo-Nozzle™
Attach your Level 1 or Level 2 Myo-Nozzle™ to any compatible bottle or straw. Keep it in your bag, at your desk, or grab it on your lunch break.
Drink as normal
Every sip requires your tongue, lips and throat muscles to engage correctly. The nozzle guides the right movement automatically — no technique needed.
Build strength passively
Hundreds of training reps built into your daily hydration. The habits you build carry over into nasal breathing at rest, in meetings, and during sleep.
Six ways it helps your working day
Sharper focus & less brain fog
Nasal breathing improves oxygen absorption by up to 18%. More oxygen to the brain means better concentration, clearer thinking and fewer afternoon slumps.
Better sleep, better mornings
Training nasal breathing during the day carries over to night. Stronger airway muscles reduce snoring, improve sleep quality, and help you wake up sharper.
Lower stress throughout the day
Nasal breathing activates the parasympathetic nervous system — your body's natural calm-down response. Less tension in meetings, calmer commutes, easier afternoons.
Breaks the mouth breathing habit
Long days encourage mouth breathing without you realising it. REMplenish retrains your tongue position and breathing pattern with every sip — no conscious effort required.
Zero disruption to your routine
No apps, no timers, no exercises. Replace your regular water bottle and the training happens automatically — at your desk, in the kitchen, or on the go.
Stay hydrated while you train
Most of us don't drink enough water at work. REMplenish gives you a reason to sip more often — building two good habits at once.
Clinically studied. Professionally recommended.
REMplenish is built on myofunctional therapy science and is currently being evaluated in a Mayo Clinic clinical trial. Independent studies show that nasal breathing improves cognitive performance, reduces stress, and supports better sleep — exactly what your working day demands.
Oxygen & Cognitive Performance
Nasal breathing produces nitric oxide, which dilates blood vessels and improves oxygen delivery to the brain — supporting sharper focus and better decision-making throughout the day.
Stress & Nervous System
Research consistently shows nasal breathing activates the parasympathetic nervous system, reducing cortisol levels and promoting a calmer, more focused mental state during high-pressure work.
Mayo Clinic Clinical Trial
REMplenish is currently being evaluated in a Mayo Clinic randomised clinical trial examining its impact on snoring and mild to moderate obstructive sleep apnoea.

My favourite thing about REMplenish is it doesn't make someone add anything extra to their life. Simply switching water bottles allows them to get stronger and help themselves.
The REMplenish nozzle is one of the best products I have seen launched for airway health — I personally use one and recommend them to every patient working to promote nasal breathing.
I've enjoyed using it and am becoming more conscious of tongue and throat muscle function with each sip. A wonderful, low-burden tool that fits seamlessly into daily life.
