Nitric Oxide, Endothelium-Derived Relaxing Factor
Effects of Nitrite on Blood Vessel Dilation in Normal Volunteers
Nitric oxide gas is important in regulating blood vessel dilation, and consequently, blood flow. This gas is continuously produced by endothelial cells, which line the blood vessels.
- Conditions
- Nitric Oxide, Endothelium-Derived Relaxing Factor, Healthy
- Trial name
- NCT00048477
- Testing
- L-NMMA and Sodium Nitrite
- Where
- United States
- Volunteers
- 42 people, healthy volunteers welcome

- National Heart, Lung, and Blood Institute (NHLBI)
Dietary Supplements: Beetroot Juice Acute Supplementation, Dietary Supplement: Placebo Acute Supplementation
Acute Effects of Beetroot Juice Ingestion on Cognitive Function and Neuromuscular Performance in Elite Female Taekwondo Athletes
Beetroot juice is a good source of nitrate (NO3-), which is a precursor of nitric oxide (NO) through the NO3- to nitrite (NO2-) to NO pathway (Lundberg et al., 2008).
