Frequently Asked Questions
Q1: What's the difference between L-Carnitine Base, Tartrate, and Fumarate?
L-Carnitine Base (inner salt) is the free form (~98% L-Carnitine). L-Carnitine Tartrate contains ~68% L-Carnitine + tartaric acid; it's more stable for tabletting. Fumarate is similar with fumaric acid. Tartrate is the most common supplement form.
Q2: What is L-Carnitine?
L-Carnitine is a naturally occurring amino acid derivative that plays a critical role in energy metabolism. It transports long-chain fatty acids into mitochondria for β-oxidation (fat burning). Highest natural levels are found in skeletal and cardiac muscle.
Q3: Can L-Carnitine be combined with other ingredients?
L-Carnitine is commonly combined with CoQ10, Alpha Lipoic Acid, Green Tea Extract (EGCG), and Chromium in energy and body composition formulations. We recommend consulting with your formulation team.
Q4: What's the regulatory status in the EU?
L-Carnitine is permitted as a food supplement ingredient in the EU. Specific regulatory status depends on intended application and labeling.
Q5: How is L-Carnitine content measured?
L-Carnitine content is quantified via HPLC with refractive index or charged aerosol detection per USP / EP methods. Titration methods are also used per Ph. Eur.
Q6: What's the typical MOQ?
Standard MOQ is 25 kg. Smaller quantities (5-10 kg) are available for evaluation.
Q7: Do you offer custom specifications?
Yes. Custom specifications (e.g., specific salt form, particle size, packaging) can be discussed with our coordination team.
Q8: What documentation is available?
Standard documentation includes COA, MSDS, allergen statement, Non-GMO statement. Additional documentation available upon request from production partners.
