This product is food-grade L-carnitine raw material powder with a purity of ≥99% (CAS No. 541-15-1), compliant with international standards for food additives. L-carnitine is an amino acid-like substance that facilitates the conversion of fat into energy; red meat is a primary dietary source. Naturally present in the human body, it functions by transporting fatty acids into mitochondria to accelerate fat burning and breakdown, thereby aiding in weight loss and body slimming. It is non-toxic and free from adverse side effects. This high-purity L-carnitine powder serves as a natural fat metabolism booster, characterized by excellent stability, superior solubility, and a wide range of applications. Widely used in global weight management and sports nutrition formulations, it offers consistent quality and regulatory compliance, making it ideal for the mass production and export of premium-grade products.
