"For example, oral vitamin C is absorbed in the small intestine…but intravenous vitamin C bypasses the gut, achieving blood and tissue concentrations that are markedly higher than those achieved with the oral form."
When I read this, I thought, ‘nose breathing is like intravenous oxygen delivery.’ It improves your body’s ability to use the oxygen you breathe, increasing tissue concentrations by 10% compared to the "oral form."
So to make it fun, let’s imagine our nose to be like an IV that injects oxygen into the organs, tissues, and muscles that need it most.
