L-Carnitine Hydrochloride raw material powder is a high-purity, crystalline, food-grade ingredient. Produced via microbial fermentation and purified through multi-stage recrystallization, the finished product is a uniform white crystalline powder free from off-odors, caking, or foreign impurities. As a key carrier in fat metabolism, it transports stored fatty acids into the mitochondria for oxidative breakdown, converting fat into usable energy for physical activity. It serves as a core ingredient for fitness supplements and weight management products, suitable for formulations such as fat-loss capsules, sports drink mixes, and oral beverages.
Production takes place in a controlled, dust-free food-grade facility, with comprehensive testing conducted in accordance with FCC and USP standards. Parameters regarding heavy metals, microorganisms, and residual organic solvents are strictly controlled. Complete export documentation is available, and the product can be supplied in stable, large-scale quantities.

What are the Product Advantages and Application Scenarios?
Product Advantages
Compared to free-form L-carnitine, the hydrochloride form features a more robust chemical structure, ensuring stability during storage without degradation. Upon entering the digestive tract, it dissolves and absorbs rapidly, continuously driving fat mobilization and breakdown. It helps delay physical exhaustion during exercise and consistently inhibits fat accumulation in weight-loss formulations, delivering sustained and steady results.
Produced via a targeted crystallization process, the granules are dry, free-flowing, and non-clumping, ensuring smooth operation during high-speed filling and tableting without mold sticking or material clogging. It dissolves quickly in both cold and hot water, yielding a clear, transparent solution. When compounded with vitamins, botanical extracts, or dietary fibers, it causes no flocculation or precipitation and does not alter the flavor or visual quality of the finished product.
Moving away from traditional chemical synthesis, the core substance is produced via biological fermentation followed by hydrochloride salt formation and refinement. This process eliminates residues of heavy metal catalysts and harmful chemical by-products. With a stable active content of ≥99%, it complies with dietary supplement ingredient standards in Europe, the Americas, and Southeast Asia, ensuring safety for long-term use.

Application Scenarios

Weight management products
Fat-loss capsules, fat-loss tablets, and meal replacement powders; these accelerate fat metabolism and reduce the accumulation of body fat.
Sports and fitness nutrition
