L-Carnitine 600mg For Sale
L-Carnitine is a natural quaternary ammonium compound (β-hydroxy-γ-N-trimethylaminobutyric acid) synthesized in the liver and kidneys from lysine and methionine. In the inner mitochondrial membrane, it plays an essential role in mitochondrial fatty acid β-oxidation by transporting long-chain acyl-CoA esters through the carnitine shuttle system (CPT I & II). L-Carnitine is studied for its role in energy metabolism, lipid utilization, mitochondrial function, oxidative stress, muscle bioenergetics, and age-related metabolic decline in laboratory research. Supplied as high-purity L-Carnitine base or L-Carnitine L-tartrate powder (≥99% by HPLC) in 600mg vials and bulk, produced in the USA.

Stereochemistry
Naturally produced L-enantiomer (D-isomer is pharmaceutically inactive) The quaternary ammonium allows binding to carnitine-acylcarnitine translocase for mitochondrial β-oxidation and ATP synthesis.
Research Applications
- Investigate mitochondrial fatty acid transport and β-oxidation efficiency
- Study energy metabolism in muscle, liver, and heart tissues
- Model metabolic disorders, exercise physiology, and age-related mitochondrial dysfunction
- Evaluate antioxidant and anti-inflammatory activity in oxidative stress models
- Assess neuroprotective potential in neuronal cultures and ischemia models
- Serve as control or co-treatment in lipid metabolism drug experiments
The 600mg size allows use across multiple experiments in cell culture, isolated mitochondria, organ perfusates, or small-animal metabolic studies.
Mechanism of Action
L-Carnitine transports long-chain fatty acids into mitochondria via CPT1/2 and the carnitine-acylcarnitine translocase, generating acetyl-CoA for the TCA cycle and ATP production. Additionally, L-Carnitine:
- Buffers acetyl-CoA buildup during high-fat metabolism
- Mitigates toxic acyl-CoA accumulation in metabolic diseases
- Scavenges free radicals and chelates metal ions (antioxidant role)
- Regulates membrane fluidity and stabilizes mitochondrial membranes
- Modulates fatty acid oxidation enzymes via PPAR pathways
Carnitine deficiency is linked to mitochondrial dysfunction, muscle weakness, and lipid accumulation.
Preclinical Research Summary
- In skeletal muscle and cardiac models, supplementation (0.5–2 g/kg diet or 100–500 mg/kg i.p.) increased fatty acid oxidation, reduced lactate, and improved exercise endurance in rats.
- In ischemia-reperfusion injury, L-Carnitine (200–400 mg/kg i.v.) reduced infarct size, preserved ATP, and diminished oxidative damage.
- Restores mitochondrial function, reduces lipid peroxidation, and improves metabolic flexibility in aging research.
- Protects dopaminergic neurons in neuroprotection models (Parkinson’s, Alzheimer’s) against amyloid-β toxicity.
- In vitro (1–10 mM) protects hepatocytes and myocytes from lipid overload and oxidative stress by increasing β-oxidation and reducing ROS.
- Improves insulin sensitivity and decreases visceral fat in high-fat diet rodent studies.
