Quick answer: Nitric oxide is a gas made by the lining of your blood vessels. It signals the muscle in vessel walls to relax, which widens them and eases blood flow. Age, smoking, inactivity and high blood sugar reduce it; exercise and vegetables rich in nitrate support it.
What it does
The endothelium, the thin lining inside your arteries, turns arginine into nitric oxide. The gas tells the surrounding muscle to relax, so the vessel widens.
What lowers it
- Smoking
- Inactivity
- High blood sugar and high cholesterol
- Ageing
What supports it
- Regular aerobic exercise
- Leafy greens and beetroot, which provide nitrate
- Not smoking
Where supplements fit
Arginine and citrulline supply raw material, but in healthy people the body usually has enough. Effects in studies are modest.
