Description
The stabilized hydrochloride salt of acetyl-L-carnitine, the acetylated form of L-carnitine that readily crosses the blood-brain barrier. Used in nootropic and cognitive-support supplement formulations, energy metabolism products, and clinical research applications.
White crystalline powder. Highly water-soluble. More shelf-stable than the free base or fumarate forms, making it the preferred ingredient for capsule and tablet manufacturing.
We supply food-grade and pharmaceutical-grade Acetyl L-Carnitine HCl from manufacturers in China holding ISO, Halal, Kosher and other certifications relevant to the product and production.
Common market grades include Standard Food Grade (98 percent minimum assay), Pharmaceutical Grade meeting USP/EP specifications, and pre-blended ALCAR with alpha-lipoic acid for premium cognitive-support supplement formulations.
Bulk and reduced-MOQ shipments. Batch-level COA covering assay, specific rotation, melting point, residual solvents, heavy metals, and microbiology.
Introduction
Acetyl L-Carnitine HCl (ALCAR HCl) is the hydrochloride salt of acetyl-L-carnitine, produced by acetylation of L-carnitine followed by hydrochloride salt formation. The acetyl group enables the molecule to cross the blood-brain barrier far more readily than free L-carnitine.
Industrial production starts from fermentation-derived L-carnitine, which is chemically acetylated and then converted to the hydrochloride salt by reaction with hydrochloric acid. The resulting salt is purified through crystallization to pharmaceutical-grade purity.
ALCAR HCl is recognized as a permitted dietary supplement ingredient in the United States and a permitted novel food in several other jurisdictions. It is listed in USP and the European Pharmacopoeia.
The dual mechanism of action (mitochondrial energy production via L-carnitine plus blood-brain barrier penetration enabled by the acetyl group) makes ALCAR HCl particularly valuable in nootropic and cognitive-support positioning. It is one of the most commonly studied ingredients in cognitive aging research.
Strategic positioning combines premium cognitive-support supplements (the highest unit value), energy and endurance sports nutrition, and broader anti-aging supplement applications.
