L-Carnitine

Name: L-Carnitine
Brand: SUN Peptides
SKU: LC600

COA on request

L-Carnitine: Helps burn fat into energy. It plays a key role in transporting fatty acids into the mitochondria — the energy-producing centres of your cells — where they are converted into usable energy. Often used to support fat metabolism, exercise performance, and recovery.

Research effects

L-Carnitine is a naturally occurring quaternary ammonium compound that plays a central role in fatty acid oxidation and energy metabolism. Clinically, L-carnitine is widely used for treating primary or secondary carnitine deficiency, improving symptoms of myocardial ischemia, heart failure, peripheral vascular disease, and diabetic neuropathy. In sports nutrition, L-carnitine is valued for its ability to promote fat burning, increase exercise endurance, reduce post-exercise muscle damage, and accelerate recovery. Furthermore, L-carnitine demonstrates positive potential in improving cognitive function, slowing neurodegenerative disease progression, and maintaining male reproductive health.

Research mechanism

L-Carnitine exerts its core metabolic function by transporting long-chain fatty acids into the mitochondrial matrix for β-oxidation. This process relies on the synergistic action of carnitine palmitoyltransferase-1 (CPT-1) and CPT-2, transferring fatty acids across the inner mitochondrial membrane as acylcarnitines to provide energy for cells. Under energy stress conditions, L-carnitine enhances fatty acid oxidation and glucose uptake through modulation of the AMPK signaling pathway. Additionally, L-carnitine's antioxidant properties enable free radical scavenging, cell membrane stabilization, and inhibition of lipid peroxidation. Its neuroprotective effects are believed to be associated with improved mitochondrial function, reduced oxidative stress, and modulation of acetylcholine synthesis.
