L-carnitine is a nutrient and dietary supplement.
It plays a crucial role in energy production by transporting fatty acids into the mitochondria of your cells.

Mitochondria act as engines within your cells, burning these fats to create usable energy. Your body can produce L-carnitine from the amino acids lysine and methionine.
In order for your body to produce sufficient amounts, you also need a large amount of vitamin C.
The main role of L-carnitine in the body is related to mitochondrial function and energy production.
In cells, it helps transport fatty acids into the mitochondria, where they can be burned for energy.
Approximately 98% of L-carnitine reserves are found in muscles, with trace amounts in the liver and blood. L-carnitine may help increase mitochondrial function, which plays a key role in disease and healthy aging.
New research illustrates the potential benefits of different forms of carnitine, which can be used to treat a variety of conditions, including heart and brain diseases. L-carnitine may be beneficial for: Recovery: improves recovery after exercise. Oxygen delivery to muscles: increases oxygen delivery to your muscles. Endurance: increases blood flow and nitric oxide production, helping to delay discomfort and reduce fatigue
Muscle soreness: reduces muscle soreness after exercise
Red blood cell production: increases the production of red blood cells, which carry oxygen throughout the body and muscles
