L-carnitine is a type of amino acid that boosts energy production in the body. It is used for various medical conditions and as a substitute supplement in those who want to shed weight. The use of L-carnitine may trigger some adverse side effects, including nausea, retching, upset stomach, loose bowel movement, seizures and heartburn.

As of 2015, there is a lack of scientific evidence to indicate L-carnitine promotes weight loss in obese and overweight patients, although some studies show that taking L-carnitine in combination with other supplements and medications may result in a decrease of body weight and body mass index, states WebMD.
