A hundred years ago, I was measuring excess Nitric Oxide and it showed depleted (no excess indicating low nitric oxide).
Months later, after all the supplements including Nitric Oxide boosters, I tested “about normal” but wasn’t feeling any better.
Today, over a year later, I used another test strip and I am so depleted that I don’t register on the strip.
I continue to read that there is a well known connection between sleep apnea and decreased nitric oxide levels.
One of the doctors on here (Ruterbusch) told patients to drastically increase l-arginine to boost NO.
This is coming full circle for me.
