The Missing Gas Your Body Depends On
Restore carbon dioxide. Support oxygen delivery. Help your body function the way it was designed to.
The CO2inhaler is designed to safely elevate carbon dioxide levels using controlled concentrations of carbon dioxide gas. Carbon dioxide is one of the most important molecules in human physiology, helping regulate oxygen delivery, circulation, nervous system function, acid-base balance, and cellular energy production. Whether your goal is better recovery, improved exercise performance, enhanced circulation, or supporting overall wellness, the CO2inhaler offers a simple way to work with one of the body’s most overlooked biological systems.

Oxygen delivery
Helps oxygen reach the cells that need it most.
CO2 tolerance

Faster recovery
Support circulation and reduce recovery time between efforts.
Most people think oxygen is the entire story
The truth is far more interesting.
Your body doesn’t simply need oxygen. It needs to be able to deliver oxygen. Every second, trillions of cells depend on oxygen reaching the mitochondria where energy is produced, but oxygen can only leave the blood when the conditions are right.
One of the most important factors controlling that process is carbon dioxide. Without adequate carbon dioxide, oxygen remains bound to hemoglobin more tightly, making it more difficult for tissues to receive the oxygen they need. This phenomenon, known as the Bohr Effect, has been understood for over a century.
Carbon dioxide isn’t merely a waste gas. It’s one of the body’s primary regulators.

The Bohr Effect
CO2 acts as a key that unlocks oxygen from hemoglobin: oxygen stays bound when CO2 is low, and is released to the tissues when CO2 is optimal.

Lungs
Oxygen enters. Carbon dioxide exits.
Blood
CO2 levels determine how easily oxygen unloads from hemoglobin.
Tissues
Oxygen moves from the blood into the tissues where it is needed.
Mitochondria
Oxygen is used to produce energy (ATP). Carbon dioxide is a natural byproduct.
Oxygen delivery isn't automatic
It depends on a delicate balance of oxygen and carbon dioxide.
Oxygen is carried by hemoglobin in your red blood cells. But for oxygen to leave the blood and enter your tissues, several conditions must be met. CO2 plays a critical role: it helps release oxygen from hemoglobin, dilates blood vessels, and supports healthy circulation so oxygen actually reaches the cells that need it.
- Adequate oxygen (O2): To load hemoglobin.
- Sufficient carbon dioxide (CO2): To release oxygen.
- Healthy blood flow: To transport oxygen.
- Responsive tissues: To utilize oxygen efficiently.

Hemoglobin carries oxygen
O2 binds to hemoglobin in the lungs.
CO2 helps release oxygen
CO2 signals hemoglobin to release oxygen in the tissues.
Blood flow delivers oxygen
Vessels dilate to increase flow and delivery.
Oxygen powers the cells
Oxygen enters cells and fuels mitochondria to produce energy.
Oxygen carried in the blood
Hemoglobin binds oxygen in the lungs.
CO2 triggers release
Carbon dioxide helps oxygen let go.
Blood flow delivers oxygen
Vasodilation ensures oxygen can reach the tissues.
Cells produce energy
Oxygen powers the mitochondria to create energy.
Carbon dioxide is the key that unlocks oxygen
Without it, oxygen stays locked away.
CO2 isn’t just a waste gas to be exhaled. It’s a vital messenger and regulator. The right amount of CO2 tells your body where oxygen is needed, helps release it from hemoglobin, and ensures it reaches the cells and mitochondria where it’s used to create energy.
When CO2 levels are too low, often from overbreathing, oxygen delivery becomes inefficient, even if oxygen levels look “normal.”
You can’t deliver what you don’t release. CO2 is the key that makes oxygen available.

CO2 creates the signal
CO2 levels inform your body where oxygen is needed most. It's the first step in the delivery process.
CO2 releases oxygen
CO2 reduces hemoglobin's grip on oxygen, allowing it to be released into the bloodstream.
CO2 dilates & improves flow
CO2 helps blood vessels relax and widen, increasing circulation and ensuring oxygen can reach tissues.
CO2 delivers energy
Oxygen reaches the cells and mitochondria where it produces energy (ATP) and keeps you functioning.
One molecule. Countless physiological roles.
Better oxygen utilization
More oxygen reaches the places that need it.
Improved energy production
Cells create more energy more efficiently.
Supports resilience & recovery
Better circulation and energy support healing and adaptation.
Calms & supports the nervous system
Healthy CO2 levels promote balance and calm.
Athletic performance & CO2 tolerance
High performers have one thing in common: they tolerate CO2 better.
CO2 tolerance is a key indicator of how well your body can handle physical and mental stress. When CO2 levels rise during exercise, it enhances oxygen delivery, improves blood flow, and delays fatigue, allowing you to perform longer and recover faster. Improving CO2 tolerance isn’t just for elite athletes. It’s for anyone who wants to move, recover, and perform at their best.
Studies show that athletes with higher CO2 tolerance:
Improved time to exhaustion
Increase in VO2 max
Lower perceived exertion

Improved oxygen delivery
Better CO2 levels signal your body to release more oxygen from hemoglobin and deliver it to working muscles.
Delay fatigue
Higher CO2 tolerance means less acidosis, allowing you to sustain intensity for longer without burning out.
Enhanced blood flow
CO2 helps blood vessels dilate, improving circulation and nutrient delivery to muscles and tissues.
Faster recovery
Better CO2 balance supports efficient waste removal and speeds up recovery between sets and workouts.
Move better. Recover better. Perform at your best.
Higher endurance
Sustain effort longer with less fatigue.
Improved efficiency
Use oxygen more effectively at every intensity.
Better adaptation
Your body adapts better to training stress and altitude.
Greater strength
Improved circulation and oxygenation support strength gains.
Reduced recovery time
Bounce back faster and train more consistently.

Better recovery
CO2 helps your body bounce back faster and stronger.
Intense physical or mental stress taxes your body, and recovery is when the real progress happens. CO2 plays a critical role by improving circulation, reducing inflammation, replenishing energy stores, and supporting the removal of waste products that contribute to fatigue and soreness.
Enhanced blood flow
CO2 helps blood vessels dilate, improving circulation to muscles and tissues for faster recovery.
Reduced soreness
Improved CO2 levels help reduce inflammation and oxidative stress that contribute to post-exercise soreness.
Restores energy faster
CO2 supports mitochondrial function and ATP production, helping you get your energy back sooner.
Removes fatigue
Better CO2 balance helps your body clear waste products like lactic acid, reducing fatigue and heaviness.
CO2 supports recovery by
Improving circulation
Delivers oxygen and nutrients where they are needed most.
Reducing inflammation
Helps calm the body's inflammatory response naturally.
Replenishing energy stores
