Nitrate
Useful mainly for endurance athletes seeking efficiency and adults wanting modest blood-pressure lowering.
Quick decision guide
May help most
endurance athletes seeking efficiency and adults wanting modest blood-pressure lowering
Common dosing range
~300–600 mg nitrate (about 5–10 mmol) per dose
When to expect effects
2–3 hours acutely; days for blood pressure
Watch out for
Avoid antibacterial mouthwash, which blocks the oral bacteria needed to convert nitrate
What is it
Dietary nitrate is an inorganic ion found abundantly in beetroot and leafy greens and sold as supplements (often as beetroot extract or sodium/potassium nitrate). In the body it is reduced to nitrite and then nitric oxide, a signaling molecule that widens blood vessels and improves oxygen efficiency in muscle. It is the active component behind beetroot juice's effects on performance and blood pressure.

AI-assisted evidence assessment — talk to your doctor before relying on any single supplement.
endurance exercise performance
Supplement benefitMeta-analyses of randomized crossover trials show dietary nitrate improves exercise economy and time-trial or time-to-exhaustion performance, reducing the oxygen cost of submaximal exercise. The benefit is consistent but modest and tends to be smaller in highly trained athletes.
Bottom line: A reliable, modest ergogenic aid for endurance, strongest in non-elite athletes.
blood pressure lowering
Biomarker supportPooled randomized trials show inorganic nitrate (mainly via beetroot juice) lowers systolic blood pressure by roughly 3–5 mmHg, through nitric-oxide-mediated vasodilation. The effect is a blood-pressure biomarker change; long-term cardiovascular outcome data are limited.
Bottom line: Modestly lowers blood pressure, a biomarker effect without proven long-term outcome benefit.

Safety
Know the common side effects, key cautions, and who should avoid it.
Common side effects
Who should avoid it
- infants (risk of methemoglobinemia)
- people advised to restrict sodium if using sodium nitrate forms
Pregnancy & breastfeeding
Beetroot foods are fine, but concentrated nitrate supplements lack pregnancy safety data; prefer dietary sources.
Interactions
additive vasodilation could lower blood pressure excessively
kills oral bacteria needed to convert nitrate to nitrite, blunting the effect
