f This was the only report of any cardiomyopathy.
ethyl)-6-hydroxychroman (α-CEHC) were excreted in the urine when a plasma threshold of 30 µmol/L (1,290 µg/dL) of α-tocopherol was exceeded. However, the α-CEHC metabolite represents only a small fraction of the α-tocopherol consumed daily, and there are few data concerning its formation. Therefore, α-CEHC excretion has not been used as a basis for assessing the α-tocopherol requirement.
Vitamin E Biokinetics
Vitamin E kinetics, metabolism, and pool size determinations in humans have been limited. Therefore, insufficient data exist for
