High Quality L-Glutamine Powder

High Quality L-Glutamine Powder - Premium Amino Acid Supplement

We are a leading supplier of High Quality L-Glutamine Powder with over 20 years experience making natural ingredients for your formulation needs. Our advanced plant covers an area of 20,000 square meters, and has purification workshops that meet 100,000-level criteria to guarantee that each batch satisfies the highest international standards. What makes our L-Glutamine unique is our innovative microbial fermentation technique using non-GMO Corynebacterium glutamicum strains and the resulting purity of over 99.5%, free of any animal-derived impurities. This means a dependably stable, vegan-friendly component that dissolves easily in cold drinks and stays intact throughout the shelf life of your product.

Product Introduction

Our L-Glutamine is the most precise amino acid synthesis process. It is a conditionally necessary amino acid (C5H10N2O3) and is the most prevalent free amino acid in human muscle tissue and blood plasma. We manufacture pure white crystalline powder with molecular weight of 146.15g/mol and optimum particle size distribution of 80-200 mesh by rigorous fermentation methods instead of chemical hydrolysis. This pharmaceutical grade ingredient tackles key formulation difficulties like fast dispersion in beverages, stability in acidic environments and zero off-flavors affecting the consumer experience. Powder you can rely on, batch after batch, whether you make recovery formulae, clinical nutrition solutions or gut health supplements.

Third-Party Test Report

Safety Check (Microbiological): Total Plate Count 1,000 cfu/g and Salmonella, E. Coli and Staphylococcus aureus all below detectable levels, in accordance with USP 61> and 62> procedures (independent lab testing by SGS) for its safe usage in nutritional supplements and therapeutic nutrition products.

Heavy Metal Analysis: Eurofins certified heavy metal levels significantly below regulatory limits: Lead <1 ppm, Arsenic <0.5 ppm, Cadmium <0.3 ppm, Mercury <0.1 ppm, fulfilling FDA & EU consumer safety requirements.

Enantiomeric Purity Confirmed: HPLC analysis provides precise optical rotation [α]20D +6.5° to +7.2° demonstrating the purity of the optical rotation and the L-isomer configuration required for biological activity and distinguishing from racemic mixes.

High Quality L-Glutamine Powder Advantages

Micronization generates particles in the 80-200 mesh size range that will dissolve entirely in cold water in 60 seconds without any clumping. Superior Solubility Profile. This allays formulator concerns about gritty textures in ready-to-drink beverages and protein shakes.

Extended Stability Window Powder does not deteriorate hygroscopically or convert to pyroglutamic acid as long as the moisture content is below 0.12%. Standard grades have a shelf life of 12-18 months. Under ambient storage circumstances you receive a 36 month shelf life.

Zero Ammonia Breakdown: Tight control of impurities keeps linked amino acids and ammonium below 0.02%, reducing the fishy odour that affects inferior batches. Your finished products have desirable flavour characteristics during distribution cycles.

High Quality L-Glutamine Powder Application

Sports Nutrition Recovery Formulas: Added at 5-10g per serving to post-workout powders to help decrease exercise-induced muscle catabolism. High purity standard prevents ammonia build-up inhibiting BCAA metabolism. Ideal for combo stacks targeting delayed onset muscle pain.

Clinical Enteral Nutrition: The principal nitrogen source in tube-feeding formulas for patients with short bowel syndrome, inflammatory bowel disease, or severe sickness. Medical-grade parameters enable quick enterocyte regeneration and lower bio-burden requirements for immunocompromised people.

Gut Health Supplements – Containing zinc carnosine and prebiotics for leaky gut repair treatments. Excellent dissolve for uniform capsule fills or sachets. Neutral pH profile to prevent destabilisation of sensitive probiotics during co-encapsulation.

Production Process

Step 1 - Strain Cultivation: Inoculate certified non-GMO Corynebacterium glutamicum into sterile glucose medium. exponential bacterial growth optimised for the beginning of glutamic acid biosynthesis

Step 2 - Fermentation Control: Maintain precise pH 7.0-7.5 and temperature 30-32°C in stainless steel bioreactors for 48-72 hours. Result: highest yield of L-Glutamine with minimum byproduct generation.

Step 3 - Filtration Separation: Pass fermentation broth through ceramic membrane filters (0.2 micron) to remove biomass. refined amino acid solution in a clear liquid concentrate.

Step 4 - Crystallization Refinement: Gradually cool filtered solution to 5°C while adjusting pH to isoelectric point 5.65. Result: homogeneous crystal formation with enantiomeric purity > 99 %.

Step 5 - Spray Drying: Atomise crystal slurry in regulated air flow chamber at 180°C intake temperature and 80°C output temperature. free flowing powder with optimum 80-200 mesh particle dispersion and <0.30% moisture content.

FAQ

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

A: Our minimum order is 25kg (one drum), and we have competitive price. Tiered discounts and specialist packaging available for larger orders.

Q: How does your fermentation-based product vary from the hydrolysed versions?

A: Fermentation generates pure L-isomer with taste character improved and free from any animal derived contamination. The bioavailability of the hydrolysed products is impacted by D-isomer impurities and residues of the processing chemicals.

Q: Do you have samples for stability?

A: Yes, we have assessment samples 100-500g with complete paperwork of COA. Samples ship within 48 hours via DHL/FedEx for speedy formulation experiments.
