Acetyl L-Carnitine occurs when L-Carnitine is combined with an Acetyl group. This variant is often referred to as Alcar.
Alcar, unlike other carnitine variants, can pass through the blood-brain barrier which it helps support brain health.
Carnitine may help transport long-chain fatty acids into your mitochondria to be used for energy.
98% of your Carnitine is stored in your skeletal muscle to help with energy transfer. A small amount is stored in your liver and blood.
