Plasma Nitrate

Oral ingestion of nitrate can increase plasma nitrate and nitrite, although they can also be used as biomarkers of nitric oxide metabolism by being able to be preserved and increased relative to their lower rate of decay. Higher plasma nitrate is associated with better blood flow.

Consistency of research results
? Scientific research does not always agree. HIGH or VERY HIGH means that most of the scientific research agrees.
Notes
grade-c Strong Very High See all 3 studies
Nitrate ingestion strongly and fairly reliabily increases plasma nitrate and nitrite.
grade-c Minor - See study
An increase in plasma nitrate has been noted with citrulline supplementation, but not to the degree of supplemental nitrate itself
grade-c Minor Very High See 2 studies
Plasma nitrate appears to be increased following carnitine ingestion, although not to the same degree as nitrate supplementation itself
