Table 7 Plasma nitrate/nitrite (μmol∙L^-1) and nitrite (nmol∙L^-1) for subjects in Study 3

	Pre Intervention	Post Intervention	30 min post intake	60 min post intake
Nitrate/Nitrite	18.6 ± 3.1	18.2 ± 2.9	18.0 ± 3.2	16.4 ± 3.0
Nitrite	1418.3 ± 137.5	1466.3 ± 146.9	1366.4 ± 148.1	1369.8 ± 200.6

Data are mean ± SEM.
No statistically significant effect noted for nitrate/nitrite (p = 0.97) or nitrite (p = 0.97).
Study involved subjects consuming 6 grams of betaine daily for 7 days; blood samples collected before (Pre Intervention) and after (Post Intervention) the 7 day period; Post intervention, subjects consumed 6 grams of betaine and blood samples were collected 30 and 60 min post intake.
