The Nobel-Winning Molecule That Tells Your Blood Vessels to Relax — And Why Your Body Makes Less of It After 40
Most people over 50 have never heard of nitric oxide. Yet it helps your blood vessels relax — and that may be connected to how warm, energetic and capable you feel every day.
It starts with little things. The stairs that used to be nothing now leave you a bit winded at the top. Your hands and feet feel cold in bed, even under the blankets.
And around 3 p.m., a heaviness settles in that coffee doesn't quite fix.
You tell yourself it's just age. Maybe it is. But researchers have spent decades studying one small, overlooked molecule that plays a central role in how your blood vessels behave — and how well blood moves through your body.
It's called nitric oxide. And chances are, no one has ever mentioned it to you.
A discovery worthy of the Nobel Prize
In 1998, the Nobel Prize in Physiology or Medicine went to three American scientists — Robert Furchgott, Louis Ignarro and Ferid Murad — for discovering that nitric oxide acts as a signaling molecule in the cardiovascular system. [1]
Put simply: nitric oxide is a messenger. It's produced in the thin lining of your blood vessels, and it tells the muscle in the vessel walls to relax.
When vessels relax, they widen. And wider, more flexible vessels make it easier for blood to flow where your body needs it.
Why it matters day to day
Healthy blood flow is how oxygen and nutrients reach your muscles, hands, feet and brain. Nitric oxide is one of the body's key tools for supporting it.
Two ways your body makes nitric oxide
Your body has two main routes for producing nitric oxide. Understanding both explains a lot.
- Vessel walls stay tense and tight
- A narrower channel for blood to pass through
- Blood cells squeeze through in single file
- Nitric oxide tells the muscle in the walls to relax
- The vessel widens
- Blood moves through more freely
Why arginine and citrulline?
Nitric oxide availability declines with age, as the body's nitric oxide system falters and oxidative stress builds over time.
Blood vessel function declines progressively with age, even in healthy adults.
Oral L-arginine is heavily broken down in the gut before it reaches the bloodstream. L-citrulline is readily absorbed and converted into L-arginine in the body. This is why many formulas pair the two.
These studies explain the science of nitric oxide and are not studies of Nitric Oxide Flow.
So what can you actually do?
Eat your greens and beets — that's the easy part of Pathway 2.
But Pathway 1, your body's own L-arginine route, is the one that tends to slow with age. Supporting it every day means giving your body the amino acids it uses to make nitric oxide.
That's exactly the idea behind a supplement from Nature's Pure Blend.
