Train your breathing
while you hydrate
Active people drink more — which means they train more. The REMplenish Myo-Nozzle™ adds gentle resistance to every sip, building better breathing habits passively across every run, ride, and session.
More exercise means more breathing — make every breath count
During exercise your breathing rate increases dramatically. The REMplenish Myo-Nozzle™ turns every hydration break into a passive breathing workout — no extra time, no extra effort. Just drink.

The Myo-Nozzle™ — passive training built into your bottle
Fill your REMplenish bottle
Fit your Level 1 or Level 2 Myo-Nozzle™ to any compatible bottle. Choose your resistance based on your current strength.
Drink as normal during training
Every sip requires your tongue, lips and throat muscles to engage correctly. The nozzle guides the right movement automatically.
Build breathing strength passively
Hundreds of effortless reps per session. No routine to remember — just drink and let the nozzle do the work.
The science behind nasal breathing and exercise recovery
Research shows that how you breathe during and after exercise has a meaningful impact on recovery efficiency, oxygen delivery, and long-term airway health. The foundation of all of it is the strength of the tongue and throat muscles that keep your airway open.
Nitric Oxide & Oxygen Delivery
Nasal breathing produces nitric oxide, which dilates blood vessels and improves oxygen delivery to working muscles — a meaningful edge for endurance athletes.
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.
View study →Better Ventilatory Efficiency
Research consistently shows nasal breathing improves ventilatory efficiency during submaximal exercise. For runners, cyclists and gym goers, nasal breathing is not only achievable — it's advantageous.
View review →Parasympathetic Recovery
Nasal breathing activates the parasympathetic nervous system — the body's rest and recover state. Mouth breathing keeps the body in a heightened stress state, slowing muscle repair after training.
Tongue Strength is the Foundation
A strong tongue positioned at the roof of the mouth supports an open, stable airway. The Myo-Nozzle™ specifically strengthens the genioglossus and pharyngeal muscles that keep your airway clear during exercise and sleep.
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.

Train the muscles that make nasal breathing possible
Most people default to mouth breathing during exercise — often without realising it. Weak tongue and throat muscles make it harder to maintain an open, stable airway, especially under physical load. The REMplenish Myo-Nozzle™ builds that strength passively — every time you drink.
- Strengthens the genioglossus — the primary tongue muscle that keeps your airway open
- Builds consistent nasal breathing habits that carry over into training
- Improves oral rest posture so your airway stays open at rest and during sleep
- Recommended by myofunctional therapists, ENTs and dentists
- Level 1 for building habits — Level 2 for greater resistance training

My favorite 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 shout out thanks to REMplenish Sleep for the opportunity to try your nozzles. I've enjoyed using it and am becoming more conscious of tongue and throat muscle function with each sip.
Pick the setup that fits your life
Every sip trains your tongue posture and promotes nasal breathing. Start with just the nozzle, or choose a complete kit with a bottle designed specifically for the Myo-Nozzle™.
Myo-Nozzle™ & Straw
The nozzle that makes it all possible. Fits any bottle with an 8–10mm straw opening — use it with what you already own. Every sip engages your tongue and oral muscles, passively building the habits that support nasal breathing, improved tongue posture, and reduced snoring. Available in Level 1 (everyday use) or Level 2 (greater resistance).
