The Claim
In healthy adults, ingestion of dietary nitrate results in measurable increases in red blood cell S-nitrosothiols and nitrite without a corresponding increase in plasma nitrite, indicating compartment-specific metabolism of nitric oxide derivatives.
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.
When healthy adults consume dietary nitrate, levels of S-nitrosothiols and nitrite rise inside red blood cells but do not rise in plasma, showing that nitric oxide derivatives are processed differently in these two compartments.
See the scientific wording
In healthy adults, dietary nitrate ingestion leads to measurable increases in red blood cell S-nitrosothiols and nitrite, but these changes occur without a corresponding increase in plasma nitrite, suggesting compartment-specific metabolism of nitric oxide derivatives.
When you eat nitrate-rich foods, your body converts the nitrate into nitrite, which enters red blood cells and binds to sulfur-containing molecules to form stable nitric oxide carriers. These carriers build up inside red blood cells but do not increase in the fluid part of the blood, meaning the nitric oxide-related activity happens only inside the cells and not in the surrounding plasma.
What the research says
1 studyAfter drinking beetroot juice, nitrite and related molecules went up inside red blood cells but not in the liquid part of the blood, showing that these molecules work differently inside the cells than elsewhere in the bloodstream.
