What is Acetyl-L-Carnitine?
Acetyl-L-Carnitine, often called ALCAR, is an acetylated form of L-carnitine that crosses the blood-brain barrier far more efficiently than its parent compound. Inside cells, carnitine shuttles long-chain fatty acids into mitochondria for energy production, supporting cellular ATP output in tissues with the highest energy demand, the brain, heart, and skeletal muscle. Clinical studies have explored ALCAR for mental energy, mild age-related cognitive decline, neuropathic discomfort, and mood support. Typical doses are 500-1,500 mg per day on an empty stomach. Benefits often build progressively over 4-8 weeks of consistent use.
Brain-penetrating form of carnitine that supports cellular energy in neurons and may improve mental energy, focus, and mood in low-energy states.
