GABA Powder Manufacturer for Bulk and Private Label

Our powder lines handle GABA from 100 g retail jars to 25 kg bulk drums. We blend in ribbon mixers with capacity up to 1,000 kg per batch. Filling runs on auger and volumetric systems with accuracy within plus or minus 2 percent. We can produce unflavoured GABA or blend with magnesium, L-theanine, glycine or melatonin. Bulk density is typically 0.5-0.7 g/mL depending on grade. We test every batch for assay, heavy metals and microbial limits before release.

For retail bottling, we run PET jars, HDPE containers and stick packs. Stick pack fill weights range from 2 g to 10 g. Bottle sizes range from 100 cc to 1,000 cc. We apply induction seals, pressure-sensitive labels and tamper-evident bands. If your brand needs a scoop or dosage spoon, we source food-grade PP scoops and insert them during packing. Line changeover takes 4-6 hours between SKUs.

GABA is hygroscopic and slightly bitter. We recommend a carrier such as maltodextrin or inulin at 20-40 percent of fill weight to improve flow and mask taste. For sleep formulas, common ratios are 100-300 mg GABA per serving with 50-200 mg L-theanine. For pre-workout, 200-500 mg GABA with 500 mg glycine. We can supply organic GABA if your label requires USDA organic or EU organic certification. Vegan and halal grades are available.

Flavour systems include natural and artificial options. We test flavour stability at 40 degrees Celsius and 75 percent relative humidity for 3 months. If your product is unflavoured, we recommend a desiccant sachet or induction seal to control moisture. We can also produce effervescent GABA powder with citric acid and sodium bicarbonate. For capsule or tablet formats, refer to our powder manufacturing overview for cross-dosage capability.

EUPHM operates a GMP-certified facility with ISO 22000 and HACCP systems. We are FDA-registered for dietary supplements. Halal certificates are available per batch. Each shipment includes a certificate of analysis covering assay, heavy metals, microbial limits and moisture. We retain samples for 2 years. For US and EU buyers, we provide documentation for customs and regulatory review. We do not claim FDA approval of any product.

Shipping terms are FOB Shenzhen or Hong Kong. Lead time for bulk powder is 20-35 working days after deposit. Retail bottling adds 5-10 days for label and packaging approval. We ship via sea, air or express. For Middle East buyers, we can arrange halal certification and Arabic labelling. Payment terms are 30 percent deposit, 70 percent before shipment. We accept wire transfer and letters of credit.

Every incoming lot of GABA powder is sampled against a retained reference standard before release to production. Identity is confirmed by FTIR and HPLC retention time against a certified standard, and assay potency is quantified by HPLC with an acceptance window of 98.0 to 102.0 percent of label claim. Microbial testing covers total aerobic count, yeast and mould, E. coli, Salmonella and Staphylococcus aureus, with results reported against the specification agreed at contract stage. Heavy metals are screened by ICP-MS for lead, arsenic, cadmium and mercury, and each lot is held under quarantine until the full panel is released by our quality team.

In-process checks run at blending, filling and sealing. Uniformity of fill weight is verified every 30 minutes on retail fills and every drum on bulk powder, with a tolerance of plus or minus 2 percent. For powder blends containing GABA, homogeneity is assessed by sampling from top, middle and bottom of the blender, and moisture content and water activity are checked to protect shelf life. Where a customer specifies a disintegration or dissolution requirement for a powder-in-capsule format, testing follows the agreed method and results are attached to the batch record rather than summarised only in the certificate of analysis.

The certificate of analysis issued with each batch lists the product name, batch number, manufacturing date, expiry date, specification number, test parameters, methods, results and pass or fail status, signed by the QC manager. Customers receive the COA, the batch production record summary and, where requested, raw material traceability back to the GABA supplier lot. Retention samples of every batch are held for the shelf life plus 12 months under controlled conditions, so any post-market query can be investigated against the original material.

Stability follows a protocol agreed per project. Accelerated conditions at 40 degrees Celsius and 75 percent relative humidity run for six months, with real-time data at 25 degrees Celsius and 60 percent relative humidity generated for the declared shelf life. GABA is hygroscopic, so we test moisture uptake, appearance, assay and microbial status at each interval. Customers launching in markets that require an expiry date supported by real-time data can request a stability study at project start, and interim reports are available at three and six months.

Retail formats for GABA powder include high-density polyethylene bottles with induction seals, stick packs, sachets and bulk drums. Bottle sizes typically run from 100 g to 1 kg, with 250 g and 500 g the most common for sleep and relaxation products. Stick packs are filled at 2 g to 10 g per stick and are suited to single-serve positioning. We can supply desiccant sachets or canisters where the powder is hygroscopic, and we confirm the closure torque and seal integrity on the first production run.

For the US market, labels are prepared to include the statement of identity, net quantity, supplement facts panel with serving size and percent daily value where applicable, other ingredients, directions for use, and the manufacturer or distributor address. We do not draft or approve claims; the brand owner is responsible for structure-function wording and for the disclaimer required for dietary supplements. Lot number and expiry date are inkjet coded on the bottle, carton and, where space allows, the stick pack, and we retain a coded sample from each run to verify legibility.

Cartons are specified to the customer's dieline, with standard corrugated board for retail and stronger board for e-commerce. Pallet configurations are agreed before production: typical counts are 48 to 60 cartons per pallet for 500 g bottles, with stretch wrapping and corner boards. For Amazon sellers, we can apply FNSKU labels and pack to the carton and pallet requirements of the fulfilment centre, including poly bagging where the retail unit is not sealed. We do not guarantee marketplace compliance, but we build to the specification the customer provides.

Bulk powder for further manufacture is packed in 25 kg food-grade drums with double polyethylene liners, sealed and labelled with product name, batch number, net weight, manufacturing date and storage conditions. Where the customer requires it, drums can be palletised and shrink wrapped for container loading. All packaging materials that contact the product are food-grade and supported by supplier declarations, and we can provide migration or food-contact documentation on request for markets that require it.

Sampling starts with a brief covering the target dose, format, packaging and destination market. We send a quotation within two working days and, once the specification is agreed, prepare samples in 7 to 10 working days. Samples are typically 100 g to 500 g of powder or a small run of filled retail units, and they are sent by courier at the customer's account. Sample approval in writing triggers the production slot, so the production window is counted from that approval rather than from the first enquiry.

Mass production runs 20 to 35 working days after sample approval for standard powder fills, depending on packaging complexity and whether labels and cartons are customer-supplied or produced by us. A pilot run below the standard MOQ of 1,000 units per SKU can be arranged for first orders, with the understanding that unit cost is higher. We confirm the production calendar in writing at order acceptance so that launch dates are planned against a fixed window rather than an estimate.

Delivery is quoted on EXW, FOB or DDP terms. FOB shipments from Guangdong ports suit buyers with their own freight forwarders, while DDP is used where the buyer wants a delivered price including duty and clearance. Air freight is used for samples and urgent launches, typically 5 to 8 days door to door, and sea freight for full containers, typically 25 to 40 days depending on destination port. We provide the commercial invoice, packing list, bill of lading and certificate of origin as standard.

Documents issued with each shipment include the certificate of analysis, material safety data sheet, and a free-sale certificate where the destination market requires one. For plant-based ingredients we can supply allergen and GMO statements, and for markets that ask for it we arrange phytosanitary certification through the relevant authority. Certifications held by the facility are GMP, ISO 22000, HACCP, halal and vegan, and copies are provided at the quotation stage so that buyers can complete supplier approval before the first order.
