We learned from a lipids researcher that CLA does not produce fat loss, muscle gain, etc. Generally, whatever supplement "marketing" says about it is not true.

There is some anecdotal correlation between CLA supplementation and fat loss, but nothing authoritative to show this. Also, an understanding of how CLA works in the body shows any fat loss probably is not due to CLA.

But it is an anti-oxidant. And it is an essential fatty acid.

There's a huge difference between smart, effective supplementation and stupid, counterproductive oversupplementation.

This isn't really something you stack with another supplement. However, you do need to consider where it fits into your total supplement program. If are are already supplementing with other fats, for example, vitamin E or perhaps an EFA supplement, then you don't want to be adding heavy amounts of CLA due to the total calories involved.

Increase the intensity of your workout (fewer reps per set, with heavier weight in each set). If you do 3 sets of 10 reps, you are sacrificing intensity for conformity.

Change that silly pattern before supplementing. You should find each set harder to do than the last, so it will necessarily consist of either fewer reps or less weight. If each set is the same, you are doing something wrong. Think about the logic, here. Then, implement the change and watch your results improve.
