possibly by regulating the PGE2 production, and improved growth
performance of pigs.

High dose of CLA have serious side effects for overweight subjects.
Daily of 3 grams of CLA treatment for 3 months was found to reduce the
insulin sensitivity in overweight men. CLA feeding promoted insulin
resistance in obese and diabetic mice. In a study, overweight volunteers
who took 4.5 grams of CLA daily for one year had an increase in their
blood levels of lipoprotein(a), a risk factor for heart disease.
