The Claim

In healthy young males, acute dietary nitrate supplementation via beetroot juice reduces systolic blood pressure by an average of 7 mmHg (95% CI: 3–11 mmHg), with substantial inter-individual variability in response, including reductions up to 24 mmHg and no change or increases in some individuals.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

In plain English

In healthy young men, drinking beetroot juice in a single dose lowers systolic blood pressure by about 7 mmHg on average, but some men experience much larger drops up to 24 mmHg, while others see no change or even a rise in blood pressure.

See the scientific wording

In healthy young males, acute dietary nitrate supplementation via beetroot juice reduces systolic blood pressure by an average of 7 mmHg (95% CI: 3–11 mmHg), but individual responses vary widely, with some individuals experiencing reductions up to 24 mmHg and others showing no change or even increases, indicating substantial inter-individual variability that exceeds random measurement error.

Why this might work

When someone eats beetroot juice, the nitrate in it enters the bloodstream, gets into saliva, is turned into nitrite by bacteria in the mouth, and then becomes nitric oxide in the blood. This nitric oxide relaxes the walls of blood vessels, making them wider and lowering blood pressure.

  1. Study: Inter-individual differences in the blood pressure lowering effects of dietary nitrate: a randomised double-blind placebo-controlled replicate crossover trial

    This study found that when healthy young men drink beetroot juice, their blood pressure usually drops by about 7 points, but some men’s drops are much bigger—up to 24 points—while others barely change. This proves people react very differently to the same drink.
