What is the recommended dosage for Acetyl-L-Carnitine?

General: 500-2,000 mg/day; Cognitive Support: 1,500-3,000 mg/day

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

Potential side effects include: Gastrointestinal discomfort (nausea, vomiting, diarrhea), Fishy body odor, Restlessness or insomnia, Increased appetite.

What is Acetyl-L-Carnitine?

Acetyl-L-Carnitine (ALCAR) is an acetylated form of the amino acid L-carnitine that crosses the blood-brain barrier more readily than standard L-carnitine. Research suggests it may support mitochondrial energy production in brain cells and has been studied for age-related cognitive concerns.

What dosage of Acetyl-L-Carnitine has been used in studies?

Clinical trials have typically used doses ranging from 500 mg to 3,000 mg per day, often divided into two or three doses. The most common dosage in cognitive studies is 1,500 to 2,000 mg daily. Consult your healthcare provider for personalized dosing guidance.

What are the potential side effects of Acetyl-L-Carnitine?

Reported side effects are generally mild and may include nausea, stomach discomfort, and restlessness. ALCAR may interact with thyroid medications and anticoagulants. Always consult your healthcare provider before use, especially if you have existing medical conditions.

About

Acetyl-L-Carnitine (ALCAR) facilitates fatty acid transport into mitochondria for neuronal energy production and provides acetyl groups for acetylcholine synthesis. Clinical evidence shows mixed results in healthy adults but more consistently positive outcomes in elderly populations with existing cognitive concerns. It is used as a prescription drug in some European countries for cognitive impairment.

How It Works

Facilitates fatty acid transport into mitochondria for neuronal energy production; provides acetyl groups for acetylcholine synthesis; exhibits antioxidant properties protecting neurons from oxidative damage; supports myelin sheath integrity.
