Everyone raves about how CLA is effective as a fat burner, but they also say it can raise your blood sugar. I once got some CLA suppliments and tried them for a day and a half but then because of this I chickend out and returned them. It also said on the bottle to take in conjunction with a low fat diet, which the paleo is not (understand it was probably just a guideline that it needs to be used in conjunction with diet and exercise). Is there any truth to this? Do any of you have any experience with it?
I think you have to differentiate the two common forms of CLA. There's the t10 c12 form that may increase blood sugar:
But there's also the c9 t11 form. When this form (the predominant one in dairy and pastured meat) is included in the supplement blood sugar levels do not increase:
Apparently most supplements are a 50/50 mixture of both forms of CLA, so it seems like it might be better to get your CLA from food.
