Nitrous oxide is, I mean, in medicine, it's a dental anesthetic, right?
It's a gas.
It's called laughing gas.
That's N2O.
It's the chemical formula.
What we're talking about is nitric oxide or NO, one nitrogen, one oxygen.
This molecule is foundational for human health and longevity.
So nitric oxide is a gas.
It's a naturally produced molecule.
It's a signaling molecule in the human body.
And so it regulates things like blood flow and oxygen delivery, and it mobilizes our own stem cells to help us recover and repair and replace dysfunctional
cells that improves energy production inside the cell, and it regulates blood flow.
So nitric oxide is a gas.
It's produced in the endothelium.
So the endothelium is the single layer of cells that line every blood vessel throughout the body.
So the function of these endothelial cells is to regulate vascular tone and to regulate, you know, solute exchange and extravasation or transport of molecules across that endothelial layer.
And so when your endothelial cells can no longer make nitric oxide gas, they no longer dilate, so the blood vessels become constricted.
You start to get inflammation.
You get stiff arteries, plaque deposition, and that's what starts cardiovascular disease or atherosclerosis.
It's not affecting the cells per se, but it's dilating the smooth muscle that surrounds the blood vessels, which leads to relaxation and dilation.
