Our brand Landnutra supplies high quality alpha gpc powder - a pharmaceutical‑grade L‑Alpha‑glycerylphosphorylcholine that arrives with more than just a certificate of analysis. Every drum comes bundled with a formulation‑ready dossier that includes forced‑degradation data at 40°C/75% RH, a photostability chart, and a compatibility grid for the twenty most common capsule and beverage excipients, so your R&D team can move directly into pilot batching without commissioning their own stress studies. The powder itself is standardised to ≥99% purity and 40–41% choline content, produced through aqueous enzymatic hydrolysis of identity‑preserved non‑GMO soy lecithin, and is available in four distinct physical grades - crystalline, micronized, granulated, and pre‑blended with a flow agent - each tuned for a specific manufacturing scenario: hard capsules, clear functional beverages, chewable tablets, or high‑speed stick‑pack lines. We also maintain a locked stability programme that follows ICH Q1A guidelines, meaning you can reference our 36‑month real‑time and 6‑month accelerated data in your own technical file without repeating the work.

Product Characteristics
Appearance – white crystalline powder in its standard form; granulated and micronized variants retain the same whiteness and do not develop off‑colour during storage.
Purity & Choline Density – Alpha‑GPC assay ≥99% (HPLC, dried basis), choline moiety 40–41%, both held to a CV of less than 0.6% across production quarters.
Physical Grades – our options: crystalline (80‑mesh, for capsules), micronized (D90 ≤18 μm, for clear beverages), granulated (dust‑free, direct‑compression), and pre‑blended with 1% tricalcium phosphate for moisture‑sensitive environments.
Solubility & Application Fit – crystalline grade dissolves in 20°C water within 90 seconds; micronized grade clears in under 30 seconds and passes a 0.2 μm filter without clogging or foaming.
Stability Package – 36‑month real‑time and 6‑month accelerated data (40°C/75% RH) available, plus a forced‑degradation report that maps pH and temperature boundaries to prevent formulation surprises.
Manufacturing & Traceability – cGMP and ISO 22000 certified; every batch is endotoxin‑tested (<0.1 EU/mg) and traceable to a single soy lecithin lot; process audit reports are available on request.
Benefits Of high quality alpha gpc powder
01 Pre‑Built Stability Dossier
Skip the six‑month wait for your own stability studies. Our ICH‑aligned programme covers real‑time, accelerated, and forced‑degradation conditions, and the data package is structured for direct inclusion in a CTD or technical file - a time‑saving asset for brands targeting the EU, US, or Australian markets.
02 Four Grades, One Specification
Rather than forcing a single powder into every format, we offer crystalline, micronized, granulated, and flow‑enhanced grades, all meeting the same purity and choline specification. Your team chooses the physical form that matches your equipment, not the other way around.
03 Compatibility Testing Done for You
Our R&D lab has already screened high quality alpha gpc powder against the twenty excipients most commonly used in capsules, tablets, stick packs, and beverages. The resulting grid - included with your first order - flags potential interactions and suggests workable pH and aw ranges, reducing the number of trial batches you need to run.
04 Responsive Technical Support
When a formulation question arises, you reach a chemist who works directly with the product - not a generic customer‑service queue. Typical response time on emailed technical queries is under four hours during business days, and we routinely ship small‑batch samples pre‑compounded with your excipients for feasibility testing.
05 Transparent, Audit‑Ready Supply Chain
Because we process identity‑preserved, non‑GMO soy lecithin and trace every drum back to a single raw‑material lot, your supplier‑qualification audit can be completed in a single site visit. Process flow diagrams, HACCP plans, and equipment‑cleaning validations are available in advance, so auditors arrive prepared.
06 Long‑Term Commercial Flexibility
We support quarterly and annual price‑lock agreements, maintain buffer stock in four regional hubs, and can scale from 25‑kg pilot orders to multi‑tonne annual contracts without changing specifications - giving your procurement team confidence to forecast and commit.
Application Fields
• Capsules & Tablets – crystalline or granulated grades for smooth, high‑speed filling and direct compression with minimal weight variation.
• Functional Beverages – micronized grade for transparent, sediment‑free ready‑to‑drink cognitive shots and powdered drinks.
• Gummies & Soft Chews – granulated grade with neutral taste and rapid dispersion during cooking.
• Sports Nutrition – pre‑workout blends, intra‑workout sticks, and recovery formulas where rapid choline delivery supports mental drive.
• Clinical & Medical Nutrition – endotoxin‑controlled powder meeting <0.1 EU/mg for enteral and oral nutritional products.
• Pet Supplements – cognitive chews for aging dogs and working animals, where clean taste and low moisture are critical.
Production Process

Non-GMO soy lecithin undergoes aqueous enzymatic hydrolysis to produce alpha-GPC, purified, crystallized and vacuum-dried. Custom particle processing and strict multi-index testing are implemented before release.
