What is REMplenish?

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)

How it works

The Myo-Nozzle™ — passive training built into your bottle

1

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.

2

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.

3

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.


Why REMplenish?

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.

The Science

Clinically studied. Professionally recommended.

REMplenish is built on myofunctional therapy science and is currently being evaluated in a Mayo Clinic clinical trial. 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.

Recommended by Sleep Doctors & ENTs

Doctors recommend Myo-Nozzles to their patients for improved sleep—without resorting to medicine or surgery.

“My favorite thing about the REMplenish concept is that it doesn’t make someone add anything extra to their life. By simply switching water bottles or straws, someone can get stronger and help themselves… I have used this product personally as well as with my family including children as young as 2 and adults as old as 75… every single human being would benefit from using this product. Anything that influences more functional breathing in a non-invasive way with low cost and high durability is worth the investment.”

Dr. Andy Sabatier
Academy West Breathing & Performance

“The REMastered sleep water bottle is a wonderful adjunct to myofunctional therapy. It really helps my patients strengthen and tone the back of the tongue and work on improving tongue thrust swallow habits. I’ve tried it myself and you can really feel the back of the tongue engaging and strengthening with each use.”

Dr. Soroush Zaghi
Otolaryngology Sleep Surgeon — The Breathe Institute

“A shout out of thanks to REMastered Sleep for the opportunity to try out your nozzles! I’ve enjoyed using it, and being more conscious of the back of the tongue and throat muscles working. I can see the value in incorporating these to help promote more normal swallowing, and tone of the throat muscles in combination with myofunctional therapy, and especially after tongue-tie release.”

Dr. Shereen Lim
Author — “Breathe, Sleep, Thrive”

“Our patients love that the product, especially the straw and mouthpiece, is convenient and portable. This helps to encourage consistent use. This is a great tool for patients with myofunctional issues and sleep breathing concerns.”

Dr. Kim Ledermann
Specialist in Orofacial Pain — Minnesota Craniofacial Center

“The REMplenish nozzle is one of the best devices I have seen invented for airway health. I personally use one and recommend them to every patient… Not just for snoring but for reposturing to promote nose breathing… We love the REMplenish Jr! Perfect ‘biohack’ to solve a problem that plagues way too many children.”
