Why L-Carnitine Continues to Grow
L-carnitine plays a crucial role in biology, transporting long-chain fatty acids to mitochondria (the cell's energy factories) for beta-oxidation, converting fat into usable energy.
Our bulk capsule products can help your brand target three core premium markets:
- Weight Management Series: Positioned as a non-stimulating metabolic catalyst, it promotes natural fat metabolism when combined with a balanced diet and exercise.
- Sports Nutrition Performance Series: Popular among athletes, it helps improve cellular energy production, endurance, and post-exercise recovery.
- Healthy Aging and Cellular Vitality Series: Acetyl-L-carnitine can cross the blood-brain barrier, making it an ideal ingredient in advanced cognitive support and mitochondrial anti-aging formulas.
OEM/ODM Customization Capabilities
We understand that time-to-market and brand differentiation are your top concerns. Our manufacturing facilities offer comprehensive contract manufacturing services:
- Own Brand/Finished Bottles: 60, 90, or 120-bottle packs in high-density polyethylene (HDPE) bottles or amber glass bottles with sensor-locked seals and customizable labels.
- Bulk Capsule Supply: Packaged in sturdy, durable, food-grade double-layered polyethylene-lined fiber drums (typically 10,000 to 50,000 capsules per drum), facilitating local filling.
- Custom Formulation: Our in-house R&D team can blend L-carnitine with synergistic ingredients such as green tea extract, chromium picolinate, or coenzyme Q10 to create bespoke products for your brand.

Certifications & EEAT Credentials
To ensure seamless customs clearance in US ports and European borders, our manufacturing infrastructure is backed by globally recognized third-party audits:
- GMP Certified: Our facility operates strictly under Current Good Manufacturing Practices verified by independent auditing bodies.
- Global Access Certifications: ISO 22000, HACCP, Halal, and Kosher certified raw materials available upon request.
- Full Documentation Suite: We provide a comprehensive Certificate of Analysis (COA) for every single batch, alongside MSDS (Material Safety Data Sheets) and stability testing data to guarantee shelf-life integrity (typically 24-36 months).
FAQ
Q1: What is your Minimum Order Quantity (MOQ) for bulk capsules?For bulk capsules in drums, our standard MOQ starts at 100,000 capsules. For fully customized private label finished products (bottled and labeled), our minimum runs typically begin at 3,000 bottles per SKU.
Q2: How do you prevent L-Carnitine from clumping or degrading during cross-border transit?L-Carnitine is highly hygroscopic (it readily absorbs moisture from the air). To combat this during sea or air freight, our capsules are packed with industrial-grade desiccants inside specialized moisture-barrier bags before being sealed in fiber drums.
Q3: Do you provide free samples for lab verification?Yes. We provide 50g-100g bulk capsule samples to qualified B2B buyers, purchasing managers, and distributors for independent HPLC (High-Performance Liquid Chromatography) testing and identity verification.
Q4: What are your typical lead times for cross-border delivery?For stock formulations and bulk capsules, lead time is 7–14 days. For full turnkey OEM private label orders (including custom packaging sourcing and printing), lead times range from 4 to 6 weeks from design approval.
