Your Nose Makes The Good Stuff. Your Mouth Skips It.

There's a gas your body makes called nitric oxide. Your sinuses pump it out all day, and it hitches a ride on every breath you take through your nose.

Open your mouth to breathe and you drive straight past it.

Yeah there's REAL science.

6× More Nitric Oxide Per Nose Breath (Because it's produced in your sinuses)

The hollow spaces behind your nose and cheekbones crank out nitric oxide nonstop — way more concentrated than anything in the air around you.1 Scientists measured a single breath in, both ways. The nose breath carried about six times more of it than the mouth breath.2. Same lungs. Same air. Wildly different delivery.

More O₂ Into Your Blood, Not Past It (Opens You Up From The Inside)

Nitric oxide relaxes blood vessels. Riding in on your breath, it widens the ones in the parts of your lungs that are actually full of air — so your blood shows up exactly where the oxygen is waiting. 3 In lab testing, oxygen levels in the body ran higher on nose breathing than on mouth breathing, every time.4

More Send Per Tank (So you feel less burned out)

More nitric oxide in your system means your body burns less oxygen to do the same work.5Researchers chased it all the way down to the cell and found it squeezing more energy out of every bit of oxygen.6Runners trained on nose breathing hit the same top-end numbers as mouth breathers while moving a lot less air to get there.7
