The L-Carnitine Injections is a weight loss treatment that helps the body turn fat into energy. L-Carnitine is a natural protein produced by the body in the liver and kidneys and stored in the skeletal muscles, heart and brain. L-Carnitine is injected intravenously (IV) which brings about an increased metabolic rate in the body. It is administered 2-3 times a week for 6 weeks with weekly monitoring of weight loss. Ideally, injections should be done early in the day to prevent sleeplessness at night. It may be associated with increased perspiration and occasionally, diarrhea.
