The evidence in words
The verdict
For blood pressure, Beetroot / Dietary Nitrate earns evidence grade B (small effect, high consistency) — there is real evidence here. Modest reduction
How it might work
Nitrate → nitrite → nitric oxide improves blood flow and mitochondrial efficiency, reducing the oxygen cost of a given workload and improving muscle contractile efficiency.
How to use it
~6–13 mmol nitrate (about one to two concentrated beet shots) 2–3 hours pre-exercise; avoid antibacterial mouthwash around dosing.
Safety & cautions
Safe; harmless pink urine/stool. Additive blood-pressure lowering with antihypertensives.
Bottom line
A real endurance aid, especially if you're not elite. Beet shot a couple hours before, and don't sabotage it with mouthwash.
How it is used
As the entry records it, from the studies it summarises. Not a recommendation for you — doses that suit a trial population may not suit you.
- Pre-exercise
- 6–13 mmol nitrate, 2–3 h prior.
