Nitric Oxide Supplements: What Nitric Oxide Is and How to Boost It Naturally – 6 Facts

Nitric Oxide Supplements: A Small Molecule With a Big Role

You often hear about nitric oxide supplements in bodybuilding and men’s health. But what is nitric oxide, why do athletes and doctors care about it, and do you really need a supplement to raise it? This article covers 6 simple facts.

1. What Is Nitric Oxide?

Nitric oxide is a gas the body makes in tiny amounts. It acts as a chemical messenger telling the muscles in blood vessel walls to relax, so vessels widen and blood flow improves. The scientists who discovered this role won the 1998 Nobel Prize in Medicine.

2. How the Body Makes It

• From arginine: via special enzymes in the vessel lining; citrulline supports this route because it is converted into arginine.
• From dietary nitrate: mouth bacteria convert nitrate from vegetables into nitrite, which the body then turns into nitric oxide.

3. Why It Matters

• Helps regulate blood pressure.
• Supports blood flow to muscles during exercise.
• Plays a role in erections – which is why ED medicines work by enhancing its effect.
• Supports the health of the blood vessel lining.

4. What Lowers Nitric Oxide?

• Smoking.
• Ageing.
• Diabetes, high blood pressure and high cholesterol.
• Inactivity.
• Frequent use of strong antiseptic mouthwash, which kills the mouth bacteria that convert nitrate.

5. Natural Ways to Support Nitric Oxide

• Beetroot and beetroot juice: rich in nitrate; studies show improved endurance in some athletes.
• Leafy greens: such as rocket, spinach and lettuce.
• Watermelon: a natural source of citrulline.
• Regular exercise: stimulates the vessel lining to make more.
• Quitting smoking: one of the most important steps for vascular health.

6. The Truth About Nitric Oxide Supplements

Nitric oxide supplements do not contain nitric oxide itself; they contain building blocks the body uses to make it – mainly arginine, citrulline and beetroot extract. Research on performance is mixed, with clearer benefits generally seen for citrulline and nitrate. To compare the two amino acids, read arginine vs citrulline and L-citrulline.

Important Warnings

• Never combine nitric oxide supplements with nitrates such as nitroglycerin.
• Be careful combining them with ED medicines, which can deepen a drop in blood pressure.
• People on blood pressure medicines should ask their doctor first.
• Erectile dysfunction can be an early sign of heart disease or diabetes, so do not rely on supplements alone.

Nitric Oxide Supplements in Combined Formulas

Some athletes prefer a product that combines arginine and citrulline, such as NOW Arginine and Citrulline with 500 mg of arginine and 250 mg of citrulline per capsule, alongside a vegetable-rich diet and regular training. For more on arginine, read L-arginine benefits.
