L-Carnitine Factory & Wholesale | High Purity Powder ≥98% for Fat Burning & Sports Nutrition
Description:
Product Overview

As a professional L-Carnitine factory and wholesale supplier, we specialize in providing high-purity L-Carnitine for fat burning and energy metabolism support. At Henan Liyin Biotech, we supply high-purity L-Carnitine in the form of a white crystalline powder.
L-Carnitine is a naturally occurring quaternary ammonium compound that plays an indispensable role in energy metabolism. It functions as an essential carrier molecule, transporting long-chain fatty acids across the inner mitochondrial membrane for β-oxidation, where they are broken down to produce cellular energy (ATP). This process is particularly critical in tissues with high energy demands, such as skeletal muscle and cardiac muscle. In addition to its role in fat metabolism, L-Carnitine also helps to modulate the ratio of acyl-CoA to free CoA, thereby stabilizing metabolic pathways.
At Henan Liyin Biotech, we supply high-purity L-Carnitine in the form of a white crystalline powder, with a minimum assay of ≥98.0% (on dried basis). Our product is available in both Feed Grade and Food Grade specifications, manufactured under strict quality controls to ensure batch-to-batch consistency and global regulatory compliance.

L-Carnitine is a naturally occurring quaternary ammonium compound that plays an essential role in energy metabolism.
It functions as a carrier molecule, transporting long-chain fatty acids into the mitochondrial matrix for β-oxidation,
where they are broken down to produce cellular energy (ATP).
This process is particularly critical in tissues with high energy demands, such as skeletal muscle and cardiac muscle.

Animal Nutrition

In aquaculture (e.g., fish and shrimp feeds) and piglet nutrition, L-Carnitine is a valuable feed additive that supports growth performance, feed efficiency, and carcass quality. Its primary role is to facilitate the transport of fatty acids into mitochondria for energy production, which is especially important for young or rapidly growing animals with high energy demands.
Key Benefits: Improves growth rate and feed conversion ratio (FCR) in fish, shrimp, and piglets. Helps reduce carcass fat deposition and improve lean meat yield by promoting fat oxidation.
Recommended Inclusion Rates: Typical supplementation levels range from 300–500 mg/kg in complete feed for aquaculture species, and 50–200 mg/kg in piglet diets, depending on species, age, and production goals.
Formulation Advantage: Our Feed Grade L-Carnitine is formulated for easy dispersion in feed premixes and pelleted feeds, ensuring uniform distribution and optimal efficacy.
️ Sports Nutrition & Health Products

For human nutrition, L-Carnitine is a popular ingredient in weight management supplements, pre-workout formulas, and energy drinks. Its well-established role in fatty acid oxidation makes it a key component of products designed to support fat metabolism, enhance exercise performance, and promote recovery.
Key Benefits: Supports the body's natural fat-burning processes by facilitating the transport of fats to mitochondria for energy. May help reduce muscle soreness and improve recovery after exercise.
Target Applications: Widely used in dietary supplements (capsules, tablets, powders), ready-to-drink (RTD) beverages, and sports nutrition bars at dosages typically ranging from 500–2,000 mg per serving.
Formulation Compatibility: Our Food Grade L-Carnitine exhibits excellent water solubility and is compatible with other popular sports nutrition ingredients, including branched-chain amino acids (BCAAs), creatine, and electrolytes.
