Natural vitamin E consists of four different tocopherol and four different tocotrienol homologues (α, β, γ, δ) that all have antioxidant activity. However, recent data indicate that the different vitamin E homologues also have biological activity unrelated to their antioxidant activity. In this review, we discuss the anti-inflammatory properties of the two major forms of vitamin E, α-tocopherol (αT) and γ-tocopherol (γT), and discuss the potential molecular mechanisms involved in these effects. While both tocopherols exhibit anti-inflammatory activity in vitro and in vivo, supplementation with mixed (γT-enriched) tocopherols seems to be more potent than supplementation with αT alone. This may explain the mostly negative outcomes of the recent large-scale interventional chronic disease prevention trials with αT only and thus warrants further investigation.
