Acetyl L-carnitine hydrochloride

Acetyl L-carnitine hydrochloride (CAS 5080-50-2), commonly abbreviated as ALCAR, is the acetylated, salt form of L-carnitine used across pharmaceutical, nutraceutical, and cosmetic manufacturing.

Acetylcarnitine hydrochloride delivers the acetyl group across biological membranes more readily than free carnitine, making it the preferred form for formulators targeting bioavailability-sensitive applications.

In dietary supplement manufacturing, ALCAR is a primary active ingredient in capsule, tablet, and powder formulations targeting cognitive support and energy metabolism.

Pharmaceutical producers use it as an active pharmaceutical ingredient and intermediate in finished-dose products. In cosmetic and personal care formulations, it functions as a humectant.

It acts as a moisturizing agent in skin creams, serums, and anti-aging products where moisture retention is a performance criterion. Sports nutrition brands incorporate it into pre-workout blends.

Functional beverages utilize this ingredient where carnitine bioavailability is a key formulation consideration. Acetyl L-carnitine hydrochloride is supplied as a white crystalline powder.

It is available in USP and food-grade specifications, with pharmaceutical-grade material meeting compendial purity requirements relevant to finished-dose manufacturing.

Bulk quantities are standard for nutraceutical and pharmaceutical procurement, with smaller quantities available for cosmetic and R&D applications.
