It is metabolized in the liver to derivatives with quinone structure (some of them have vitamin activity). It is excreted with bile – more than 90% (some amount is absorbed again and is subjected to enterohepatic circulation) 6 % by the kidneys (as glucuronides of tocopherolactonic acid and its gamma-lactone).
