alpha-Carboxyethyl hydrochroman (alpha-CEHC) has been identified as a major water-soluble metabolite of vitamin E, which circulates in the blood and is excreted in the urine (PMID: 12420750). About one-third of the alpha-CEHC circulating in the blood is present as alpha-CEHC glucuronide (PMID: 10552913). 2,5,7,8-tetramethyl-2-(2-carboxyethyl)-6-hydroxychroman (alpha-CEHC) has been identified as a major water-soluble metabolite of vitamin E, which circulates in the blood and is excreted with the urine.
