L-Carnitine 5000mg

L-Carnitine is an endogenous amino acid derivative with a molecular formula of C7H15NO3, molecular weight of 161.20 g/mol, and CAS number 541-15-1. It is biosynthesized from lysine and methionine primarily in the liver and kidneys, and plays an essential role in mitochondrial fatty acid metabolism.

Research has established L-Carnitine’s primary function as the required cofactor for carnitine palmitoyltransferase (CPT) enzymes that transport long-chain fatty acids across the inner mitochondrial membrane for beta-oxidation. Without sufficient carnitine, long-chain fatty acids cannot enter the mitochondrial matrix for energy production, shifting cellular metabolism toward glucose dependence.

Preclinical and clinical studies document L-Carnitine’s effects on exercise metabolism, with research showing enhanced fatty acid oxidation during submaximal exercise, reduced lactate accumulation, and improved recovery markers following high-intensity exercise. Studies also demonstrate protective effects against exercise-induced oxidative damage and muscle injury.

Research in cardiovascular models shows L-Carnitine supplementation improves myocardial energetics, reduces ischemia-reperfusion injury, and enhances cardiac function in heart failure models. Studies in metabolic research demonstrate improved insulin sensitivity and glucose disposal, particularly in insulin-resistant states characterized by carnitine deficiency.

Each vial contains 5000mg (5g) of L-Carnitine solution for research applications.
