Product Introduction

Improved cellular energy metabolism is a result of the transfer of long-chain fatty acids into mitochondria by conditionally necessary vitamin L-carnitine. This white crystalline powder is ideal for use in dietary supplements, sports drinks, and functional foods because to its excellent water solubility and purity (>2500 g/L at 20°C). Produced by lysine and methionine, the physiologically active L-form is C7H15NO3 with the CAS No. 541-15-1. Your compositions will have the highest levels of stereochemical purity and bioavailability thanks to this pharmaceutical-grade material that undergoes stringent quality control.

Product Specification 

Bulk L-Carnitine Powder Advantages

Molecular Weight Efficiency: Offers the greatest free L-Carnitine per gram compared to salt forms like L-Carnitine L-Tartrate, allowing you to reduce capsule size or meet therapeutic dosage with fewer ingredients.

Improved Bioavailability: The free base form is quickly absorbed and used, with 95% accumulating in cardiac and skeletal muscle tissue, where fatty acid oxidation generates ATP.

Pharmaceutical-Grade Purity Our regulated production method removes D-Carnitine contamination, which is biologically inactive and may interfere with L-Carnitine transport systems, allowing for optimal effectiveness in your finished products.

Processing Versatility: The high water solubility profile is amenable to liquid delivery systems, ready-to-drink drinks and effervescent tablets. The regulated particle size distribution optimises flowability for high-speed encapsulation and direct compression tableting.

Application of Bulk L-Carnitine Powder

Sports Nutrition Supplements: L-carnitine bulk powder is Used in pre-workout and fat burner products to increase the metabolism of fatty acids during exercise, and to increase energy, recovery and endurance.

Weight management supplements assist to transform stored fat into energy, particularly when taken with carbohydrate-rich meals to enhance absorption at the cellular level.

Functional Beverages: Excellent water solubility makes it ideal for energy drinks, isotonic beverages and protein shakes, allowing customers to conveniently supplement on-the-go without textural issues.

Cognitive Health Formulations: Base form is not Acetyl L-Carnitine, but is a precursor in specialised neurological support products for mitochondrial function and cellular energy needs in brain tissue Bulk L-Carnitine Powder.

Production Method

Step 1 – Selection of Raw Materials: Obtain pharmaceutical-grade lysine and methionine precursors from recognised sources, perform inbound quality inspection for identity, purity and contaminant screening to guarantee that the quality of the biosynthetic substrates fulfils the standards for enzymatic conversion.

Step 2 - Biosynthetic Fermentation: Microbial fermentation in 100,000-level cleanrooms under optimised temperature, pH and nutrient conditions. Controlled microbial fermentation results in naturally occurring L-Carnitine with correct stereochemical configuration by enzymatic catalysis.

Step 3 - Purification and Crystallisation: Purification is performed by multi-step chromatographic separation and recrystallisation. This process removes contaminants, D-isomers and residual fermentation by-products, producing medicinal purity levels greater than 99% and meeting the optical rotation standards.

Step 4 – Quality Check and Packing: Full analysis by HPLC, GC and spectrophotometric methods, put into fibre drums with double-layer PE bags, stored in moisture regulated conditions to avoid hygroscopic decomposition during transportation.

Third Party Test Report

Verified independently. Our quality claims are supported by more than internal testing. International laboratories like SGS and Eurofins evaluate our products intensively.

Pesticide Residue Testing EU regulation (EC 396/2005) and USDA organic criteria are met using multi-residue analysis (detection limit < 0.01 mg/kg for over 500 pesticide compounds).

Heavy Metal Analysis: Further ICP-MS testing indicates lead, arsenic, cadmium, and mercury levels are far below FDA and EU limits, ensuring long-term supplement safety.

Microbiological Safety: Pharmaceutical-standard testing for total plate count, yeast, mould, E.coli, Salmonella, and Staphylococcus aureus to ensure product integrity throughout controlled storage.

OEM/ODM support

Custom Formulation Development: Our R&D team, consisting of over 20 experienced experts, partners with you to create custom mixes of L-Carnitine with complimentary compounds such as green tea extract, conjugated linoleic acid, or branched-chain amino acids for synergistic benefits.

Multi-Formulation We produce soft capsules, hard capsules, tablets, sachets and instant powders to your requirements using our extensive production lines and particle engineering expertise to optimise product performance.

Private Label Packaging: Full-service branding solutions including bespoke label design, multilingual compliance documents and packaging customisation from retail bottles to bulk food-service containers that correspond with your market positioning.

Support of Regulatory Documentation: We offer COAs, allergy statements, GMO-free declarations, nutritional data, stability studies and Proposition 65 compliance papers to accelerate your product registration and market entrance procedures.

FAQ

Q: What is the minimum order quantity for your L-Carnitine powder?

A: Our MOQ is usually 25kg (1 drum). But we can provide samples from 20-100g for test in formulation before complete production.

Q: How do you avoid moisture absorption in storage?

A: We pack in fibre drums with double layer thicker PE bags inside. We suggest to store in sealed containers with temperature below 25°C and humidity control as the powder is quite hygroscopic.

Q : Do you have any documents on customs clearance?

A: Yes, we can provide full export documents including commercial invoice, packing list, COA, health certificate, and origin certificate for seamless international shipment.

Q: What is the shelf life when properly stored?

A: When sealed, cold, dry, and protected from heat and light, the product will fulfil Specification for 24 months from manufacturing.

Q: What technical help do you provide for formulation problems?
