An acetate form of (±)-α-tocopherol; inhibits heat-stress-induced decreases in blastocyst number in pregnant mice and GSH levels in isolated mouse zygotes in a model of hypothermia-induced pre-implantation embryonic death at 1 g/kg; prevents sidestream cigarette smoke-induced decreases in body weight and lung dynamic compliance and increases in lung resistance in mice at 1,050 IU/kg in the diet; increases IL-1β, IL-4, and IFN-γ levels in BALF in the same model
