Vitamini E ni kundi la misombo ya mumunyifu ya mafuta ambayo ni pamoja na tocopherols nne na tocotrienols nne.Ni mojawapo ya antioxidants muhimu zaidi. Ni vimumunyisho vya kikaboni vyenye mumunyifu kama vile ethanoli, na visivyoyeyuka katika maji, joto, asidi thabiti, labile-msingi. Vitamini E haiwezi kuunganishwa na mwili yenyewe lakini inahitaji kupatikana kutoka kwa chakula au virutubisho. Vipengele vinne vikuu vya vitamini E asilia, ikijumuisha d-alpha, d-beta, d-gamma na d-delta tocopheroli zinazotokea kiasili. Ikilinganishwa na fomu ya synthetic (dl-alpha-tocopherol), aina ya asili ya vitamini E, d-alpha-tocopherol, inahifadhiwa vizuri na mwili. Upatikanaji wa kibayolojia (uwepo wa kutumiwa na mwili) ni 2:1 kwa Vitamini E ya asilia juu ya Vitamini E ya sintetiki.
