Build a better breathing routine
one sip at a time
REMplenish is a breathing training system built around the Myo-Nozzle™. It adds gentle resistance to drinking through a straw, encouraging consistent, repeatable nasal breathing practice throughout the day, at home, work, school, or on the go.
Nasal breathing training built into your water bottle
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 and a healthy airway, with no separate exercises, no routine, and no extra time.
- Strengthens the tongue and throat muscles that keep your airway open
- Promotes nasal breathing patterns over mouth breathing
- Improves oral rest posture with every sip
- 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. Choose your resistance based on your starting strength.
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, during exercise and during sleep.
Six reasons people switch to the Myo-Nozzle™
Supports better sleep
Stronger airway muscles reduce the vibration in soft tissues that causes snoring, building better breathing habits day and night.
Promotes nasal breathing
Trains correct oral rest posture and tongue position with every sip, encouraging the nasal breathing patterns your body is designed for.
Strengthens tongue & throat
Targets the genioglossus and pharyngeal muscles, the muscles that keep your airway open and stable during sleep and exercise.
Fits into your daily routine
No separate exercises, no extra time. Simply switch your water bottle and let the nozzle do the work throughout your day.
Supports exercise recovery
Nasal breathing is linked to faster post-exercise recovery and better oxygen efficiency. REMplenish helps you build that habit passively.
For the whole family
Used by adults and children from age 2 to 75. Recommended by myofunctional therapists, ENTs, dentists and sleep doctors worldwide.

Learn moreThe science behind the nozzle.
REMplenish is built on myofunctional therapy science. Independent studies on oropharyngeal exercises, the foundation of the Myo-Nozzle™, show consistent improvements in breathing habits, snoring and airway strength.
Nitric Oxide & Oxygen Delivery
Nasal breathing produces nitric oxide, which dilates blood vessels and improves oxygen delivery to working muscles, a meaningful advantage for active people.
Faster Post-Exercise Recovery
A 2025 peer-reviewed study found nasal breathing resulted in significantly faster post-exercise muscle recovery, linked to improved nitric oxide bioavailability.

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 genuinely fits into daily life.
