Beetroot Extract (Dietary Nitrate)
Other ·Exploratory record · not publication-reviewed ·Updated July 13, 2026
Beetroot extract provides dietary nitrate that can raise nitric oxide availability and modestly lower blood pressure. It is also used before exercise to improve efficiency and endurance, with best evidence in recreationally trained athletes and variable benefit in elite athletes. Oral bacteria are required for nitrate-to-nitrite conversion, so antibacterial mouthwash can blunt effects.

What the research says.
A quick, data-only summary. The full evidence, dosing, and sources are below.
Beetroot Extract (Dietary Nitrate) is an other most often used for may lower systolic blood pressure, may improve endurance exercise efficiency, may improve time-to-exhaustion in some users. NutriStack rates the overall evidence as strong. A typical adult dose is 300-600 mg nitrate 2-3 hours pre-exercise, or 400-800 mg nitrate/day for blood pressure protocols, commonly taken as nitrate-standardized beetroot juice shot or capsule. This profile indexes 3 sources.
The bottom line
Evidence rating strong. Most-documented uses: may lower systolic blood pressure, may improve endurance exercise efficiency, may improve time-to-exhaustion in some users. 3 sources indexed (2009–2017), with 0 interaction records on file.
How it works, mechanistically.
Core mechanism
Dietary nitrate is absorbed and concentrated in saliva, where oral bacteria reduce it to nitrite. Nitrite can then be converted to nitric oxide, especially under low-oxygen and acidic conditions, supporting vasodilation, blood pressure reduction, mitochondrial efficiency, and muscle oxygen delivery. Beetroot also supplies betalains and polyphenols, but standardized nitrate content is the main performance-relevant feature.2,3
Dosing & protocol.
Peak nitrate/nitrite effects often occur 2-3 hours after dosing. Avoid antibacterial mouthwash around dosing because oral bacteria are needed for conversion.1,2
