What is Acetyl L-Carnitine?

Acetyl L-Carnitine provides a more bioavailable source of L-Carnitine, an important amino acid produced within the body [1, 2]. L-Carnitine plays a crucial role in proper heart and brain function, muscle movement, along with several other body processes [1]. Moreover, L-Carnitine allows the body to convert fat into energy [3]. Although it is not common, some people suffer from L-Carnitine deficiencies due to certain health conditions or medications [2]. L-Carnitine, although produced in the body, can also be found in red meat, dairy products, fish, poultry, wheat, asparagus, and several other sources [2, 3].

Benefits of Acetyl L-Carnitine

Acetyl L-Carnitine supplementation provides the body with many benefits, not the least of which is its roles in fighting free radicals – such as reactive oxygen species – and in enhancing cellular metabolism [1, 2, 3]. By boosting the energy available in the mitochondria of cells, Acetyl L-Carnitine is able to promote physical and mental energy [2]. Acetyl L-Carnitine supplementation is also incredibly beneficial for proper heart and nervous system function.

Acetyl L-Carnitine (ALCAR) Dosage

Typical recommended dosage for Acetyl L-Carnitine is 500mg taken 2-3 times per day. It is best to start with smaller dosage and gradually increase as necessary based on how your body responds to the supplement [2]. Acetyl L-Carnitine has been found to be safe for most adults when taken properly, but reactions with certain medications may occur, so it is best to consult with your physician before supplementing. Side effects such as stomachache, nausea, vomiting, and restlessness are mild and typically only occur in much higher doses [2].
