Tocotrienol supplementation brings about various favourable effects including improving lipid profiles, lowering of thromboxane B2 and platelet factor 4 and reduced LDL oxidation.

Therefore, to study the anti-atherogenic effects of tocotrienols supplementation, serial MR angiography of the carotid arteries are done.
