CLA Side Effects

Nausea, loose stools, and heartburn are some of the possible side effects reported with CLA. These are generally insignificant if CLA is obtained through dietary means. However, supplements may cause potentially serious side effects. You should notify your healthcare provider right away if you experience any serious side effects, such an unexplained rash, swelling, or difficulty breathing.

Does CLA Cause Side Effects?

CLA (conjugated linoleic acid) is a fatty acid that is found in dairy products and certain meats. When obtained through the diet, CLA is unlikely to cause significant side effects. However, supplements may cause side effects, some of which can be serious. There are different forms (known as isomers) of CLA, and manufactured CLA usually has more of the isomer that seems to be responsible for some of the negative side effects of CLA (compared to naturally occurring CLA found in dairy and meat).

(This article covers many, but not all, of the possible side effects with CLA. Your healthcare provider can discuss a more complete list of CLA side effects with you.)
