The Claim
In healthy young males, the within-individual response to dietary nitrate supplementation for systolic blood pressure and plasma nitrate concentration is highly consistent across repeated doses, with correlation coefficients of 0.80 and 0.91, respectively.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In healthy young men, the change in systolic blood pressure and plasma nitrate levels after taking dietary nitrate supplements is consistently similar each time the supplement is taken.
See the scientific wording
The within-individual response to dietary nitrate supplementation for systolic blood pressure and plasma nitrate is highly consistent across repeated doses in healthy young males, with correlation coefficients of 0.80 and 0.91 respectively, indicating that individuals who respond strongly to one dose are likely to respond similarly to subsequent doses.
When a person eats nitrate-rich food, the nitrate enters the bloodstream, gets pumped into saliva, turns into nitrite by bacteria in the mouth, is swallowed, and becomes nitric oxide in the blood. This nitric oxide relaxes blood vessels, lowering blood pressure. The same person’s body always follows this exact process the same way each time, so their blood pressure drops by the same amount every time they eat the same amount of nitrate.
What the research says
1 studyIf a guy’s blood pressure drops after drinking beetroot juice once, it’s very likely to drop again the next time he drinks it — his body reacts the same way each time, even if other people react differently.
