- Essential in releasing energy from fat.
- Supports muscle and heart health.
- Supports healthy insulin levels.
Dairy and red meat contain the greatest amounts of L-Carnitine. Only small amounts are found in plants, such as avocado and some fermented soy products (e.g., tempeh).
L-Carnitine is made in the body from the amino acids l-lysine and l-methionine (synthesized in the kidneys). It is needed to release energy from fat. L-carnitine releases energy by removing short-chain and medium-chain fatty acids from mitochondria. Build-up of these fatty acids interferes with mitochondrias' bioenergy-producing process, which can lead to muscle weakness and fatigue.
L-Carnitine is used for supporting muscle and heart health. Many studies have reported favorable results using L-Carnitine to promote cardiovascular health and to enhance athletic performance and endurance.
It is also used for supporting healthy insulin levels and energy production.
- If you have chronic liver disease, avoid L-Carnitine due to impaired L-Carnitine metabolism or increased L-Carnitine biosynthesis leading to overly high levels of this amino acid derivative.
- Coenzyme Q-10 and L-Carnitine may have synergistic effects.
- An increase in seizure frequency or severity has been reported in people with a history of seizures using L-Carnitine orally or intravenously.
