Nitric Oxide

Definition

Nitric Oxide is a molecule that the body produces naturally, which helps increase blood flow and reduce blood pressure.

Scientific / Technical Definition

Nitric Oxide (NO) is a signaling molecule produced by the endothelium and plays a crucial role in vascular smooth muscle relaxation, leading to vasodilation and increased blood flow. It is synthesized from the amino acid L-arginine by the enzyme nitric oxide synthase (NOS).

Benefits

• Improves blood circulation
• Enhances exercise performance
• Reduces muscle soreness
• Lowers blood pressure
• Supports cardiovascular health

Examples

• Beets
• Garlic
• Leafy greens like spinach and kale
• Meats and seafood high in amino acids like L-arginine

Additional Information

• Effects: Nitric Oxide helps to relax and widen the blood vessels, thereby improving circulation and delivery of oxygen and nutrients to muscles during exercise. This can enhance performance and endurance.
