I'd want to see a lot more evidence than one 8 week clinincal trial. The Ateronon pill is not designed to lower cholesterol but "to help inhibit the oxidation of LDL cholesterol, a leading cause of plaque build-up in the arteries".
Plant sterols and stanols which occur naturally in fresh vegetables, fruits, nuts, pulses and oils plant oils such as rapeseed, safflower and sunflower have been clinically proven to do the same job very effectively. Furthermore, the natural dietary sources of sterols and stanols are probably better absorbed by the body.
