Neither of those articles stipulated the following (which can be found in the article in this forum futher down the list):

• The only brand of CLA that has been proven to provide fat burning / muscle staving benefits when tested on humans has been the TonalinTM brand. It differs from the others in that it contains a 50/50 blend of the cis-9/trans-11 and trans-10/cis-12 isomers.

Dosage is recommended at 3.4 - 4.2g (but keep in mind that a 1g pill will only contain between 740-820mg of CLA)
