It is made in the endothelium — the single layer of cells lining the inside of every blood vessel you have. Three researchers shared a Nobel Prize for working out what it does there.
The endothelium produces nitric oxide continuously. The body builds it from the amino acids L-arginine and L-citrulline, and from dietary nitrate found in foods such as beetroot.
The molecule signals the smooth muscle in the vessel wall to relax. The vessel widens. This happens thousands of times a day, everywhere in the body, without you noticing.
A wider vessel carries more blood — and with it more oxygen and more nutrients, to muscle, to brain, to everything downstream.
The description above concerns the general role of nitric oxide in human physiology, not the effect of any product. Nitric oxide production is understood to decline with age.
L-arginine and L-citrulline are the amino acids your body uses to make nitric oxide. Beetroot extract is a natural source of dietary nitrate. Here is exactly how much of each you get — no proprietary blend, no hidden ratios.

Bengt Fellström is professor of nephrology at Uppsala University and senior consultant at Akademiska Sjukhuset. He is also a part-owner of BioConcept AB, the company behind Flexovital.
When the 1998 Nobel Prize in Medicine went to the discovery of nitric oxide as a signalling molecule, it caught his attention. Nitric oxide was not his own field — but he saw what the discovery meant, and thought it deserved to reach further than the research community.
That became the starting point for Flexovital, developed during his time at Akademiska Sjukhuset. Not an off-the-shelf raw material someone else had formulated, but an original formula built around that molecule — six ingredients, in doses printed openly on the pouch.
The 2024 Nutrients study is preclinical. It was not a clinical trial in humans and does not establish an effect in humans. We describe it here because the complete formula was tested at all — which is unusual in this category — not as evidence of a health benefit.
