🧠 What Is Nitric Oxide and Why Does It Matter for ED?
Nitric oxide (NO) is a molecule your body produces naturally. It plays a critical role in relaxing blood vessels, improving blood flow, and enhancing oxygen delivery — all essential functions for healthy sexual performance.
As we age, nitric oxide production declines, which can lead to poor circulation and lower performance. That’s where nitric oxide supplements come in.
