What Is Acetyl-L-Carnitne?

Acetyl-L-carnitine is an amino acid (a building block for proteins) that is naturally produced in the body. It helps the body produce energy.

Acetyl-L-carnitine is used for a variety of mental disorders including Alzheimer’s disease, age-related memory loss, late-life depression, thinking problems related to alcoholism, and thinking problems related to Lyme disease. It is also used for Down syndrome, poor circulation in the brain, cataracts, nerve pain due to diabetes, nerve pain due to drugs used in the treatment of AIDS, and facial paralysis.

Some men use acetyl-L-carnitine for infertility, symptoms of “male menopause” (low testosterone levels due to aging), and a disease of the penis called Peyronie’s disease.

The body can convert L-carnitine to acetyl-L-carnitine and vice versa. But, no one knows whether the effects of acetyl-L-carnitine are from the chemical itself, from the L-carnitine it can make, or from some other chemical made along the way. For now, don’t substitute one form of carnitine for another.

How does it work?

Acetyl-L-carnitine helps the body produce energy. It is important for heart and brain function, muscle movement, and many other body processes.

What is it and where does it come from?

Acetyl-L-carnitine is a dietary supplement, and the acetyl ester of L-carnitine, is used to support a healthy memory. It occurs naturally in animal products. Chemically, acetyl-L-carnitine is known as beta-acetoxy-gamma-N, N, N-trimethylaminobutyrate. Other names for acetyl-L-carnitine include: acetyl-levocarnitine, acetylcarnitine, l-acetylcarnitine, levacecarnine, and ST-200. Acetyl L-Carnitine is a modified amino acid that supports cellular energy production by assisting in the transport of fat into the mitochondria where it is oxidized and converted into ATP (chemical energy for the cell). Acetyl L-Carnitine is in a highly bioavailable form of L-Carnitine antioxidant effect, helps to maintain healthy cellular energy metabolism and supports brain function.

What does it do and what scientific studies give evidence to support this?

Acetyl-L-carnitine may support healthy cardiac function. It may have antioxidant and anti-apoptotic activity.

Who needs it and what are some symptoms of deficiency?

Acetyl-L-carnitine levels may decrease with advancing age. However, because it is not an essential nutrient, true deficiencies do not occur.

How much should be taken? Are there any side effects?

Most research involving acetyl-L-carnitine has used 500 mg three times per day, though some research has used double this amount. You should consult with your doctor, pharmacist, or nurse about how much acetyl-L-carnitine you should take. The dosage depends on the strength of the medicine and the reason you are taking acetyl-L-carnitine. If you are using acetyl-L-carnitine without first consulting your caregiver, follow the directions on the label. Do not take more acetyl-L-carnitine or take it more often than what is written on the directions.

Where can I get it?
