L-Carnitine

L-carnitine is a biologically active substance naturally present in the body. It is a safe and effective compound that plays a key role in fat breakdown and energy production in the human body. Its primary function is to transport fatty acids into the interior of mitochondria, the cellular "powerhouses" where, among other things, fatty acid breakdown occurs. This is why the highest concentrations of carnitine are found in tissues that primarily use fatty acids as their energy source, such as the heart and skeletal muscles.

In a healthy body under normal conditions (in the absence of mental and physical stress), the body produces enough carnitine in the liver and kidneys to meet its needs. Carnitine is transported from the liver and kidneys to the aforementioned tissues that utilize fatty acids for energy. To produce L-carnitine in the body, in addition to the amino acids lysine and methionine, certain nutrients are required, including vitamin C, vitamin B6, niacin, and iron.

Natural sources of carnitine include the red meat of mammals, particularly beef, as well as wheat, avocados, asparagus, and peanuts. Although these foods contain carnitine, significant quantities of this nutrient cannot be obtained through diet alone, making supplementation necessary. L-carnitine is known, according to numerous studies, to have an impact on muscle growth and development, increased energy, resistance to muscle fatigue, and post-exercise recovery.
