CRP and atherosclerosis: Also one study showed that CLA administration (50:50 isomer blend of c9, t11 and t10, c12) with 3 g/day dose after 2-months decreased inflammation and oxidative stress markers include high sensitivity C-reactive protein (hs-CRP) and malondialdehyde (MDA), and significantly increased levels of the antioxidant Glutathione peroxidase (GPx) in atherosclerosis patients, but had no effect on circulating IL-6 [26].
