Would love to see the reference mate if you've got it. I'm jumping on the CLA bandwagon ASAP, too many health and body composition benefits associated with that supplement to avoid it!
I was incorrect, the study went up to 7g of CLA not 8g.
There are a fortitude of benefits, including lower everything in your blood levels.
However there are also drawbacks to CLA:
Although no severe adverse events have been related to the use of CLA, there are reports of effects of CLA on several risk factors for chronic disease (reviewed in 41 and 42). CLA has been shown to slightly increase biomarkers of inflammatory disease (usually within the published normal values), including C-reactive protein (43), white blood cell counts (33, 35), and blood and urinary isoprostanes (24). Elevations of these biomarkers have been suggested to be indicators of inflammatory disease (44-46) but have also been shown to be antiinflammatory (47). In addition, although CLA does increase these suggested biomarkers of inflammation, animal studies strongly suggest that CLA is not proinflammatory but antiinflammatory. CLA decreased and reversed atherosclerosis (48-50), decreased antigen-induced airway hypersensitivity (51-52) and improved airway response in humans (53), increased life expectancy in a mouse lupus model (54), decreased inflammation in a model of arthritis (55), decreased bowel inflammation in a pig model (56), and reduced endotoxin- induced (57) and cancer-induced (58) cachexia in many animal models. Thus, although CLA has been shown to cause a modest increase in inflammatory markers, it has also been shown to decrease inflammatory disease in several models. The relevance of these elevated biomarkers of inflammation taking into account the decrease in inflammatory disease remains to be determined.
CLA has also been reported to increase insulin resistance (24, 28, 59). This has been most notable in studies of short duration (59), those that used single isomers (24, 28), or both. For example, in one study, insulin resistance was reported in individuals supplemented with only the t10, c12 isomer for 12 wk, but not with a mixed preparation of predominantly the c9, t11 and t10, c12 isomers (24). In a later study, the same enriched t10, c12 supplement was given for 18 wk and did not result in insulin resistance (25). Many studies either have not found significant changes in fasting glucose or insulin or in measures of insulin sensitivity (17, 19, 25, 27, 31, 32, 34-36, 60-67) or have found an improvement (30, 35, 62). With regard to both safety and efficacy, it has been suggested that CLA preparations enriched in c9, t11 and t10, c12 isomers are preferable to preparations containing 4 isomers (41), and this may also be true compared with single isomer preparations. Further investigation into the safety of CLA is warranted.
I'm not citing all of those studies, you can find them here:
