L-Carnitine is a naturally occurring compound that plays a key role in energy production by transporting fatty acids into the mitochondria, where they are burned for fuel. It is particularly popular among athletes and fitness enthusiasts for its potential to enhance fat metabolism and improve exercise performance.
L-Carnitine is also known for its antioxidant properties, which may help reduce muscle damage and soreness after intense workouts. Additionally, it has been studied for its potential benefits in supporting heart health and cognitive function.
While L-Carnitine is generally safe, excessive supplementation may cause mild side effects such as nausea, stomach cramps, or a “fishy” body odor.
