Faction Labs 100% Pure Acetyl L-Carnitine 150g Online Only

Acetyl-L-Carnitine (ALCAR) is a biologically active form of L-Carnitine, an amino-acid-like compound naturally present in the body. It plays an important role in energy metabolism by assisting in the transport of fatty acids into the mitochondria, where they can be used to produce energy.

The acetylated form of L-Carnitine is known for its ability to cross the blood–brain barrier more readily than standard L-Carnitine. Because of this, Acetyl-L-Carnitine is commonly used in products designed to support both physical and cognitive performance, particularly during periods of increased mental or physical demand.

In the context of exercise and sport, Acetyl-L-Carnitine is often included to support energy production and training output as part of an active lifestyle. It is frequently used by individuals engaged in endurance training, high-volume resistance training, or calorie-controlled phases where efficient energy utilisation is a priority.

Acetyl-L-Carnitine is also involved in acetylcholine metabolism, which is why it is commonly featured in nootropic and focus-oriented formulations. This dual role makes it a versatile ingredient across performance, training, and everyday supplementation.

ALCAR is typically well tolerated, mixes easily, and can be used alongside other amino acids, pre-workouts or recovery products as part of a balanced nutrition and training program.
