Urinary α‐CEHC Predicts α‐Tocopherol Status in Healthy Adults and Those with Metabolic Syndrome

More than 90% of Americans do not consume the estimated average requirement (12 mg) of vitamin E, but dietary intakes are poorly correlated plasma α‐tocopherol (α‐T) concentrations, which are apparently normal. Plasma α‐T is an insensitive biomarker of α‐T status because α‐T increases with lipid levels and in individuals with hyperlipidemia, circulating α‐T increases, but delivery of both lipids and α‐T to tissues is compromised. We hypothesized...
