What is Acetyl-L-Carnitine (ALCAR)?

Acetyl-L-Carnitine is an acetylated form of L-carnitine, an amino acid derivative involved in mitochondrial energy metabolism. It can cross the blood-brain barrier and is used to support cognitive and nerve health.

What are the main benefits of Acetyl-L-Carnitine?

ALCAR is commonly used to support memory and attention, mood, and nerve function. It is also used for symptoms of peripheral neuropathy, including diabetic or chemotherapy-related neuropathy.

What is a typical Acetyl-L-Carnitine dosage?

Common supplemental amounts range from 500 to 2000 mg per day, often split into 1–2 doses. Individual needs vary by goal, age, and tolerance.

What are common side effects of Acetyl-L-Carnitine?

Possible side effects include nausea, stomach upset, headache, restlessness, or insomnia, especially if taken later in the day. If side effects occur, lowering the dose or taking it earlier may help.

Who should be cautious with Acetyl-L-Carnitine?

People who are pregnant or breastfeeding, have a seizure disorder, or take thyroid medication or blood thinners should consult a clinician before use. It may also interact with certain medications, so review your full medication list with a healthcare professional.
