摘要：This study aimed to systematically review and analysis of the effects of dietary supplements, in particular L-Carnitine and Conjugated Linoleic Acid (CLA) on the reduction of body fat. We systematically reviewed articles published from 2000 until August 2010. The databases were consulted: PubMed, HighWire, Medline, ScielO and EBSCOhost. For detection of articles, we used the descriptors listed below: Conjugated linoleic acid, L-Carnitine, Supplementation, Weight loss and Obesity. Among the most important findings related to the use of CLA, there is the weight reduction, side effects such as increased insulin resistance, elevated blood glucose and fasting insulin levels, elevated lipid peroxidation and reduced HDL-cholesterol in subjects with metabolic syndrome. For supplementation with L-carnitine, smaller studies had scientific plausibility, since no one could prove the effectiveness of this supplement to reduce body fat. Thus, the recommendation of such supplements with specific purpose of weight loss should be avoided for specific cases and the recommendation should be made cautiously. Key words: Conjugated linoleic acid; L-Carnitine; Supplementation; Weight loss; Obesity.
