Nobody knows: Cla is a supplement sold to consumers. Some studies show possible good effects, while others show possible bad effects. Cla is not an fda-approved medication, so it is untested and unproven what brand of cla, what type of cla, or what amount of cla will do in a particular person's body, regardless of his thyroid status. Finding good human research studies on such supplements is usually impossible.

No way to be certain: Supplements such as conjugated linoleic acid are sold by health food stores, online, and elsewhere with no direct oversight by the fda or other responsible bodies so one cannot be sure of what one is getting. Even if it's pure, i know of no conclusive evidence of benefit, nor of harm, in the setting of hypothyroidism or hypoparathyroidism.

In referring to the Natural Medicines Comprehensive Database 2010, the main disease interaction is with Diabetes / metabolic syndrome as certain forms of the drug (isomers) can produce hyperproinsulinemia and insulin resistance. Whether the combinations of the different isomers of conjugated linoleic acid available in commercial products has the same risk is unknown.
