Our 20,000 square meters production site with 100,000 level purification workshops and SGS standard laboratories, backed by over 20 years production experience, ensures that each batch of product complies with international cGMP, FSSC22000, ISO22000, Halal and Kosher certification, providing you with supply chain reliability and formulation confidence for muscle protein synthesis and metabolic health applications.

Product Presentation

This product is the most important necessary amino acid for protein synthesis, especially important for repairing muscle tissue and stimulating anabolic signalling via activation of the mTOR pathway. Assay Purity 99%. CAS No.61-90-5. Accuracy of Formulation and Bioavailability. White Crystalline Powder. This pharmaceutical grade substance is manufactured by modern fermentation and purification procedures, with excellent solubility and stability. Each 25kg barrel is tested for heavy metals, microbiological contaminants and pesticide residues before to delivery to ensure conformity to European Pharmacopoeia and USP requirements for your finished products manufacture.

Third Party Test Report

Purity Verification: Independent SGS testing verifies ≥99.0% L-Leucine content using HPLC technique, with enantiomeric purity >99.5% L-form.

Heavy Metal Screening: Testing by Eurofins shows lead <0.5ppm, arsenic <0.3ppm, cadmium <0.2ppm and mercury <0.1ppm, far within FDA and EU regulatory limits.

Microbiological Safety: Total plate count <1,000 cfu/g Yeast and mould <100 cfu/g Salmonella, E. coli and Staphylococcus aureus negative in 25g.

Leucine Bulk Powder Advantages

​​​​​​​Pharma-Grade Purity Chemical syntheses include trace contaminants, but our fermentation technique eliminates them, improving medical safety.

Optimised particle size distribution (80 mesh) ensures consistent flow in automated filling equipment, reducing production downtime and waste.

Validated Bioavailability: Pre-workout/intra-workout formulations absorb faster due to the crystalline composition's quick stomach pH degradation.

Extended Shelf Stability: Moisture level <0.5% avoids clumping and retains efficacy for 36 months with correct storage conditions.

Product Specification

Leucine Bulk Powder Benefits

Sports Nutrition Supplements: The main active ingredient in BCAA formulations, often at 2:1:1 ratios, used to enhance muscle protein synthesis and workout recovery.

Clinical Nutrition Products: Roles in medicinal foods for sarcopenia, cachexia, and age-related muscle wasting diseases.

Functional drinks: Ideal for ready-to-drink protein drinks and meal replacement shakes in need of instantized amino acid profiles.

Animal Nutrition: Formulates better feeds for livestock and companion animals, resulting in better growth rates and feed conversion efficiency.

Manufacturing process

Step 1 – Microbial FermentationSelected strains of Corynebacterium glutamicum are cultured in controlled aerobic fermentation in 5,000L bioreactors and converted into L-Leucine at a >50g/L concentration and biotechnological efficiency, with no petrochemical dependencies.

Step 2 – Multi-stage Purification The cell-free fermentation broth is passed via ion-exchange chromatography columns and activated carbon filtration beds to remove endotoxins and pigments to achieve pharmaceutical-grade purity of >99%

Step 3 – Crystallisation and Drying: The concentrated leucine solution is crystallised by controlled cooling, then separated by centrifugation and dried in a fluid-bed dryer at carefully controlled temperatures to produce homogeneous crystalline particles with optimised bulk density.

Step 4 – Quality Check: Each batch of Leucine Bulk Powder is subjected to a 17-point quality inspection at our SGS-certified laboratory, which includes HPLC assay, residual solvent analysis, and microbiological testing, before getting batch release permission.
