Background: Other than the in vitro erythrocyte hemolysis test, no
valid biomarkers of vitamin E status currently exist.
Objective: We hypothesized that the urinary vitamin E metabolite
a-carboxyethyl hydroxychroman (a-CEHC) could serve as a biomarker.
Design: The relations between urinary a-CEHC, plasma a-tocopherol,
and vitamin E intakes were assessed by using a previously

and we concurrently collected plasma and...
