The Mechanism
Your blood is already full of oxygen. CO2 tells your cells to take it.
Most recovery tools try to push more oxygen into your body. CO2 therapy works differently. It helps the oxygen you already have reach the tissue that needs it.
Here is how it works. CO2 touches your skin. Your blood vessels open. Hemoglobin — the protein that carries oxygen in your blood — lets that oxygen go. Your muscles, joints, and skin get what they need. This is called the Bohr Effect. Christian Bohr described it in 1904. Every med school still teaches it. CO2 therapy is how we signal the same mechanism on purpose.

"Your blood is already full of oxygen. The question is whether it's getting to your cells."
Ross Schilling is a chiropractor with a biology degree. He spent years watching patients recover faster when oxygen reached the tissue that needed it. He couldn't see every patient. So he built a product that does the teaching for him. This is what he says when a new athlete walks into his clinic.
