Acetyl-L-Carnitine
The Mitochondrial Energy Shuttle
Acetyl-L-Carnitine (ALCAR) is the acetylated form of L-carnitine, an amino acid derivative that plays a crucial role in energy metabolism. ALCAR transports fatty acids into mitochondria for energy production and crosses the blood-brain barrier to provide unique cognitive benefits. It's essential for sustained physical and mental energy.

Scientific animation showing the mechanism of action of Acetyl-L-Carnitine
ALCAR acts as a shuttle, transporting long-chain fatty acids across the mitochondrial membrane where they can be burned for energy. Without adequate carnitine, fatty acid oxidation is impaired and energy production suffers. The acetyl group in ALCAR provides additional benefits: it crosses the blood-brain barrier (regular L-carnitine cannot), supports acetylcholine synthesis, and provides neuroprotective effects.
Timing: Best given in the morning or before activity for energy support
Energy benefits often noticed within 1-2 weeks; cognitive benefits develop over 4-8 weeks.
ALCAR has an excellent safety profile with extensive research. It's naturally produced by the body and found in foods like red meat. No significant adverse effects have been reported at supplemental doses. May have mild stimulating effects—some prefer morning dosing.
