„Fat-burner“ L-Carnitin?
german translation / full articleQuestion
L-Carnitin is frequently advertised as „fat-burner“ und recommended for weight loss. Is there any evidence for this assertion?
Answer
Theoretical considerations argue against administration of L-carnitin in healthy persons. Results from RCTs of low quality are contradictory as to weight loss. Laboratory studies show changes of metabolism in athletes´ muscle cells but only when combined with ingestion of large amount of carbohydrates (not a reasonable idea in weight reduction).
