Nitric Oxide Supplement
This is probably my least favorite supplement and the first one I will likely quit as it is FOUR capsules per serving. I added this supplement because I began testing my NO levels using saliva strips (strip results are in my journey thread)
The more I read about nitric oxide depletion, the more I wondered if that was part of my issues. According to the data, if you have low NO in your body, Viagra and others are less likely to work. And at one point this year, 100mg Viagra wasn’t doing the trick.
Others on this board have posted about their NO supplements, focusing on either Arginine or Citrulline. I decided to try this one because it had both amino acids at a reasonably high quantity; and included L-Arginine HCL, which is the “better” choice for the body.
Arginine is not suggested with “chronic” low blood pressure. I have low blood pressure, but not at a dangerous level.
There are also studies that show citrulline is NOT as effective as Arginine. You will also find some people who swear by it.
My nitric oxide levels have increased since I started with the supplements, so this is one of the few that I can say I have verified as working. The saliva strips show that my levels went from DEPLETED to THRESHOLD.

Recent studies suggest that NO is a major physiological stimulus for relaxation of penile vasculature and trabecular smooth muscle, essential for penile erection. Relaxation of the trabecular smooth muscle of the corpus cavernosa leads to a decreased vascular resistance and increased blood flow to the penis. Alongside the increased flow, venous outflow is reduced by the compression of the subtunical venules. The combination of increased inflow and decreased outflow causes penile engorgement and erection.
