Other details -
L-carnitine is a nutrient widely available in supplement form and often marketed as a weight loss aid. Made naturally in the body, L-carnitine is essential for transporting fat into cells to produce energy.While many supplement manufacturers claim that L-carnitine can speed up metabolism, there is little scientific support for L-carnitine s ability to promote weight loss.
Health Benefits of L-Carnitine for Weight Loss
To date, few clinical trials have tested l-carnitine s effectiveness as a weight loss aid.The available research includes a 2000 study from the International Journal of Sport Nutrition and Exercise Metabolism, in which 36 moderately overweight premenopausal women were given either L-carnitineor a placebo twice daily for eight weeks. Analyzing study results, researchers found no difference in total body mass or fat mass between those who took L-carnitine and those given the placebo.A number of animal studies have also shown that L-carnitine may not support weight loss. A 2002 study from the Annals of Nutrition and Metabolism, for instance, found that rats treated with l-carnitine did not experience a greater reduction in body fat levels compared to a control group.What s more, a 2005 study published in theInternational Journal for Vitamin and Nutrition Research found that rats fed an L-carnitine-enhanced diet tended to gain more weight than other animals in the study (despite no difference in their intake of calories).
In some cases, L-carnitine supplements may produce certain side effects (including nausea, abdominal cramps, diarrhea, and a "fishy" body odor).In addition, L-carnitine may interact with antibiotics used in the long-term prevention of urinary tract infections (such as pivampicillin).
