The Claim

Among healthy young males, the between-participant variability in systolic blood pressure response to dietary nitrate supplementation exceeds the minimal clinically important difference of 2 mmHg in approximately half of participants (8/15).

Supports is higher

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

In plain English

In healthy young men, half of the individuals experience a drop in systolic blood pressure from dietary nitrate that is larger than the smallest change considered meaningful for health.

See the scientific wording

The between-participant variability in systolic blood pressure response to dietary nitrate supplementation in healthy young males exceeds the minimal clinically important difference of 2 mmHg for approximately half of participants (8/15), suggesting that a substantial proportion of individuals may experience physiologically meaningful reductions.

Why this might work

When a person eats nitrate-rich food, the body absorbs the nitrate, sends it to the mouth, where bacteria turn it into nitrite. The nitrite is swallowed and becomes nitric oxide in the blood, which relaxes blood vessel walls, allowing more blood to flow and lowering blood pressure. Some people have more of this conversion happening than others, so their blood pressure drops more.

    Some guys who drank beetroot juice saw their blood pressure drop a lot, while others saw only a small change — and for about half of them, the drop was big enough to matter for their heart health.
