What is Carnitine?

L-carnitine, a compound present in almost all cells in the body, helps in the process of metabolizing fatty acids into energy. L-carnitine is chemically similar to an amino acid, and is manufactured in the liver and kidneys from the amino acids L-lysine and L-methionine. L-carnitine is naturally occurring in many animal source foods and a few plant source foods such as avocado.

Health Benefits

Because L-carnitine is primarily manufactured in the liver and kidneys, supplementation of the compound in those with liver or kidney disease may be necessary due to impaired L-carnitine synthesis.

Studies are being conducted on the benefit of acetyl-L-carnitine (produced in the brain) to those with Alzheimer’s disease. These studies are promising, but more research is needed.

There is conflicting research as to the benefit of L-carnitine on exercise performance and obesity. Most promising is the advantage L-carnitine may provide to endurance athletes. More research is needed.

Usage Indications

Use as directed. Dosages vary; general recommended dosage is 500-1000mg, 2-3 times per day. Supplement can be taken with or without food.
L-carnitine is available in capsule, liquid, and tablet form.

Amino acids are often given a prefix of L- or D-. Choose L-carnitine, as it is most similar to the compound produced in the body.

• Side effects: May cause mild gastrointestinal discomfort. In rare cases, L-carnitine may cause seizures in those with no pre-existing seizure disorder. In those with a preexisting seizure disorder, L-carnitine may increase the frequency and/or the severity of seizures. Consult your physician. An unusually high dose of L-carnitine may cause an undesirable body odor.
• Indications: It is not recommended that those who are pregnant/nursing take L-carnitine supplements, as safety has not been proven.

What is Acetyl-L-Carnitine?

Acetyl-L-Carnitine (a.k.a. acetyl-carnitine ,L-acetylcarnitine ,ALC) is the acetyl ester of L-carnitine.

Naturally produced in the brain, Acetyl-L-carnitine helps the brain use the neurotransmitter acetylcholine.

Health Benefits of Acetyl-L-Carnitine

Because it helps the brain utilize acetylcholine, proper Acetyl-L-Carnitine dosage may improve brain health. Acetyl-L-carnitine is especially promising for those who suffer from age-associated dementia such as Alzheimer’s disease.

Acetyl-L-Carnitine dosage may also improve heart health, and have antioxidant properties. Acetyl-L-Carnitine may improve sperm motility, which may indirectly increase fertility.

Acetyl-L-Carnitine Dosage Indications

Use as directed. Be careful not to confuse Acetyl-L-Carnitine with N-acetylcysteine or L-carnitine.

• Side effects: May cause mild gastrointestinal discomfort. In rare cases, Acetyl-L-Carnitine may cause seizures in those with no pre-existing seizure disorder. In those with a preexisting seizure disorder, Acetyl-L-Carnitine may increase the frequency and/or the severity of seizures. Consult your physician.
• Indications: Pregnant/nursing women should not take Acetyl-L-Carnitine supplements, as safety has not been proven.
