How to source GABA powder without guessing the purity grade
What we establish before quoting a GABA order. GABA enquiries usually arrive with a competitor price and no sheet, so the first thing we confirm is the assay basis and the method behind it: ours is gamma-aminobutyric acid at 99% or higher by HPLC, from fermentation rather than chemical synthesis. We then ask which format the powder goes into, because gummies, capsules, evening drinks and confectionery pull mesh and dissolution behaviour in different directions. Then documentation: every lot ships with a batch COA naming the assay and the method.
GABA is one of the easiest ingredients to buy badly. The same name covers fermentation material and synthetic material, at assays quoted on different bases, and the price gap looks like a bargain until the COA arrives. The grade we supply is gamma-aminobutyric acid at 99% or higher by HPLC, fermentation-derived, a white crystalline powder at 80 mesh. This guide covers the specification line by line, what it is bought for, and what a first order looks like.
What GABA powder is, and what the 99% line commits to
The sheet reads gamma-aminobutyric acid at 99% or higher, assayed by HPLC, from Lactobacillus fermentation followed by purification and crystallisation. Three parts of that sentence carry commercial weight. The number is a purity floor, reported per lot. The method is what makes the figure comparable — 98% by titration and 99% by HPLC are not the same statement, and buyers who compare them directly mis-price the material.
The route matters too. Fermentation-derived GABA costs more to make than synthetic and is bought for clean-label positioning, so that line is a claim you pay for. If a quotation sits far below the market for a 99% grade, ask whether the material is synthetic, then whether the assay was run by HPLC at all.
The specification, line by line
| Line | Standard grade |
|---|---|
| Product | Gamma-aminobutyric acid (GABA) |
| Source / route | Fermentation (Lactobacillus), purification, crystallisation |
| Assay | GABA 99% or higher, by HPLC |
| Appearance | White crystalline powder |
| Particle size | 80 mesh |
| Loss on drying | 5.0% or less |
| Packing | 25 kg fibre drum, double polyethylene liner |
| Shelf life | 24 months in unopened original packing |
| MOQ | 1 kg |
Two lines get read more carefully than the rest. Loss on drying at 5.0% or less is free moisture, and in a crystalline amino acid it predicts caking in a humid kitchen. The mesh line is 80: the crystals dissolve readily, so a finer mesh buys speed nobody needs while costing flow on the filling line.
The batch COA carries results against these limits plus the micro and heavy-metal lines a manufacturer needs: lead below 1 ppm, total plate count below 1,000 cfu/g, E. coli and Salmonella absent. Indicative values on a standard lot sit near 99.2% assay and 0.6% loss on drying, so the grade has headroom over the floor.
What GABA powder is bought for
Four formats cover almost every enquiry, and what changes between them is the mesh fit and the trial, not the material:
- Sleep gummies. Dissolves into the cook with a clean taste and no colour contribution, which is why it is the default active in the format. Dose is per piece, so the assay floor matters.
- Capsules. Filled in a dry blend at 80 mesh; the free-flowing crystal keeps fill weight consistent.
- Evening and night drinks. Dispersed in the mix step; the clean taste is why it works in a ready-to-drink line where a bitter active would need masking.
- Functional chocolate and confectionery. Lower inclusion, where loss on drying and neutral flavour matter more than mesh.
We supply this as a raw ingredient for manufacturing, not for personal use or retail sale, and we make no therapeutic claims for it: the categories above describe where the powder is formulated, not what a finished product may say. Sleep wording is tightly policed and its status varies by market, so pack copy is the buyer's call.
What a first order looks like
- MOQ: 1 kg
- Samples: drawn from production lots, so what you test is what would ship; the free quantity depends on the item's value, the rest at cost plus courier
- Sample and pilot packing: 1 kg and 5 kg foil bags
- Bulk packing: 25 kg fibre drum with a double polyethylene liner
- OEM: available under your own brand, artwork under confidentiality
- Lead time: in-stock items ready in about 2 days; bulk production 3 to 5 working days after deposit
- Transit: Xi'an to Shenzhen about 3 days, then 6 days by air to major U.S. and EU airports, or 18 to 25 days by sea
The pattern that works is a 1 kg sample against your own specification, a pilot at the inclusion rate you intend to declare, then a drum. Buyers who skip the pilot come back with a dissolution question the COA cannot answer, because dissolution in a gummy cook is process behaviour, not a specification line.
Reading two GABA quotations side by side
When a buyer sends a competitor offer, we read four things in order. The assay and its method: 99% or higher by HPLC, per lot. The route: fermentation or synthesis. It explains most of a price gap. The documentation: a lot COA with micro and heavy metals, not a catalogue sheet. The packing: a 25 kg drum with a double liner, not a single bag.
Frequently asked questions
What is GABA powder standardised to?
Gamma-aminobutyric acid at 99% or higher by HPLC, on a Lactobacillus fermentation route followed by purification and crystallisation. White crystalline powder at 80 mesh, loss on drying 5.0% or less, and a batch COA with every lot naming the assay and the method.
What should I check when comparing GABA suppliers?
The assay and its method: 99% or higher by HPLC, per lot. Then the route, fermentation or chemical synthesis, which explains most of a price gap. Then the COA lines that matter downstream: lead below 1 ppm, total plate count below 1,000 cfu/g, E. coli and Salmonella absent.
What is the MOQ, packing and lead time for GABA powder?
MOQ 1 kg; 1 kg and 5 kg foil bags for pilots; 25 kg fibre drum with a double polyethylene liner for bulk. In-stock material ships in about 2 days, bulk production takes 3 to 5 working days after deposit, and transit is about 3 days to Shenzhen plus 6 days by air or 18 to 25 days by sea.
