LCLT is an outstanding stuff
l-Carnitine tartrate, naturally found in some foods, acts to stabilize l-carnitine. l-Carnitine is a dipeptide found in great abundance in the body, especially the heart and skeletal muscle. It maintains efficient fat utilization by transporting long-chain fatty acids into the mitochondria where they can be broken down by a process called beta oxidation (fat metabolism) to produce energy. A recent study reported that oral l-carnitine supplementation in healthy subjects promotes optimal long-chain fatty acid oxidation. Additionally, l-carnitine helps to clear short and medium chain fatty acids from the mitochondria that would otherwise accumulate over time. This helps to keep metabolic processes running smoothly and efficiently. l-Carnitine also promotes cardiovascular health by supporting ventricular function and antioxidant activity. Additionally research also suggests a role for l-carnitine in supporting muscle repair after strenuous exercise. The results of one study indicated an attenuation of muscle strain and fatigue when exercisers were given l-carnitine-l-tartrate supplements prior to completing a high repetition strength regimen, suggesting l-carnitine may help reduce post-exercise recovery time.
Recommended dosage is 2000 mg in divided doses, between meals.

But maybe can check another form of it
l-Carnitine fumarate promotes healthy fat metabolism, oxygenation of the heart muscle, and enhances high intensity training much like l-carnitine-l-tartrate. However, unlike most forms of carnitine, l-carnitine fumarate provides dual support for energy production and cardiovascular function in addition to providing a stable form of carnitine. Fumarate is a key compound in the Krebs cycle, which is the major energy-producing pathway preceding the electron transport chain. This intimate connection with energy metabolism makes l-carnitine fumarate an excellent supplement for enhanced muscle and fat metabolism support.
