Brief Summary:

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.

Condition or disease Intervention/treatment Phase
Healthy Procedure: consumption of CLA enriched food Not Applicable

Detailed Description:
Each volunteer receives CLA enriched products for a total of 3 weeks containing approximately 20g CLA per day. A control group is not needed. If three subjects or more show one or more blood values for liver and kidney function above predefined limits the study will be terminated.
