Effect of Conjugated Linoleic Acid Intake on Liver and Kidney Function

July 5, 2007 updated by: Wageningen University

The Effect of Conjugated Linoleic Acid Intake on Liver and Kidney Function in Healthy Volunteers (CLAxon-Study)

The knowledge of the health effects of CLA on the human body is limited. However, CLA supplements are sold over the counter in several countries and various techniques are used to increase the content of CLA in food.

The CLAxon-study will be performed to investigate wether high doses of CLA can be safely given to healthy human volunteers.
