L-Carnitine is a naturally occurring compound essential for energy production in the human body. Its chemical formula is C₇H₁₅NO₃, and it is scientifically known as (R)-3-Carboxy-2-hydroxy-N,N,N-trimethylpropanaminium hydroxide inner salt. This white or off-white crystalline powder plays a critical role in transporting long-chain fatty acids into mitochondria, where they are oxidized to generate energy. L-Carnitine is widely used in nutritional supplements, feed additives, and pharmaceuticals due to its metabolic benefits. Hebei Fuyang Biotechnology Co., LTD. specializes in producing high-purity L-Carnitine through precision-controlled purification processes. This ensures superior physiological activity, making it an effective metabolic enhancer. The product’s unique properties include: These features make L-Carnitine a valuable additive in both human nutrition and animal feed industries. Complies with GB 34461-2017 "National Standard for Feed Additive L-Carnitine". L-Carnitine’s versatility makes it suitable for various applications: Recommended dosages vary by species: It improves reproductive performance, reduces feed conversion ratios (FCR), and enhances growth rates. L-Carnitine boosts growth and reduces FCR in fish, making it a critical additive in aquaculture feed. Used in dietary supplements to support fat metabolism, energy production, and athletic performance.
