Alpha GPC 99 Powder

Shaanxi Hongda Phytochemistry Co., Ltd. makes Alpha GPC 99 Powder, a high-quality cognitive support product

Shaanxi Hongda Phytochemistry Co., Ltd. is one of the leading companies in the development and supply of API raw materials. Our Alpha GPC 99 powder is a cognitive enhancer with extremely high purity. We use enzymes to break down phosphatidylcholine to produce glycerophosphocholine. We then use a special purification method, including chromatography and crystallization under strict GMP conditions, to ensure the best quality and consistency of the product. Our Alpha GPC powder is tested to be at least 99% pure (verified by HPLC), low in heavy metals (less than 1 ppm), low in residual solvents (less than 0.05%), and meets USP microbial limits.

• 99% Anhydrous High-Efficiency Purity: Alpha-GPC >99.0% / Determined by ion-pair high-performance liquid chromatography (IPLC). Hongda's quality control center fully utilizes a modified ion-pair reversed-phase high-performance liquid chromatography (RP-HPLC) method. The effective loading of each batch is consistently greater than 99.0% (fully meeting or even exceeding USP/EP pharmacopoeia standards), ensuring the brain-targeted acetylcholine conversion rate of the finished product from the source.
• Better blood-brain barrier crossing bioavailability, powder stability for longer shelf life, and memory and brain protection in dietary supplements, sports nutrition, and functional foods.

Why Choose Alpha GPC 99 Powder?

When you want to make supplements that work, Alpha GPC 99 Powder is the best source of choline. This very concentrated form has at least 99% purity and helps with brain protection, cognitive function, and physical performance. Our powder is made in FDA-inspected, cGMP-certified facilities and meets strict pharmacopeial standards (USP/EP). It is perfect for people who make things and want to put bioavailability and compliance first. This ingredient is the most flexible and dependable choice for making nootropics, sports nutrition products, or anti-aging products.

Key Benefits

✅ 99% Purity: HPLC testing demonstrates its potent and stable efficacy.

✅ Free Choline Residue: Less than 0.5% (controlled by high-sensitivity ion-pair chromatography peak area limits), eliminating the source of volatile putrid odors such as trimethylamine, resulting in a pure, tasteless, and excellent palatability in the final product of the compound powder.

✅ Critical Relative Deliquescence Humidity: CRH greater than 28% (high-precision stable crystal surface modification control test), ensuring it does not become damp in air, and providing extremely uniform and stable flow rates for fully automated capsule filling.

✅ Complies with GMP, ISO 9001, and FDA-DSHEA standards in various countries.
✅ Suitable for various types of products, such as tablets, capsules, and powder mixtures.

Shaanxi Hongda's 99% High-Purity Alpha-GPC Production Process:

1. Natural high-purity, high-glycoside natural soybean lecithin (PC > 98%) is completely dissolved in pharmaceutical-grade anhydrous ethanol under low pressure: In a fully sealed, dry stainless steel reactor, carefully selected ultra-high-purity soybean lecithin molecules are fully dissolved in anhydrous ethanol to prepare a high-abundance homogeneous reaction mother liquor.

2. Quantitative pulse addition of a highly active, specific solid-phase alkaline catalyst for highly selective transesterification hydrolysis: A self-developed mild alkaline catalyst is slowly introduced into the reaction mother liquor, targeting and cleaving the two fatty acid ester chains of the lecithin molecules at a constant temperature of 40℃, precisely hydrolyzing them into the alpha-glucosine backbone.

3. Continuous flow tubular high-speed centrifugation for rapid removal of the low-polarity free soybean fatty acid ester byproduct layer: Utilizing the powerful physical and mechanical centrifugal force of a centrifuge, the oily free fatty acid byproducts insoluble in the highly polar aqueous phase are rapidly and completely removed and discarded through solid-liquid two-phase separation.

4. Dynamic gradient adsorption of byproducts and impurities using a multi-stage cross-flow strongly acidic cation exchange resin chromatography column: The coarse filtrate is slowly pumped into an ion exchange chromatography column matrix packed with customized pore sizes. Utilizing the difference in charge adsorption, free choline and residual trace inorganic salts are directionally captured and eluted.

5. High-efficiency continuous thin-film double-effect vacuum evaporation-distillation concentration system for rapid low-temperature removal of residual ethanol and water: The eluted high-purity Alpha-GPC solution is fed into a low-temperature vacuum multi-effect falling film evaporator, where it is rapidly concentrated into a high-concentration colloidal syrup in a vacuum environment below 45°C and without oxygen.

6. Low-temperature forced recrystallization by slowly injecting a polar composite inducing agent into an ultra-sealed sterile crystallizer: Ice-crystal anhydrous ethanol is introduced into the concentrated syrup as a crystallization inducing agent. Under constant temperature of 0°C and shear stirring at a specific speed, highly hydrophilic Alpha-GPC molecules are induced to precipitate crystal nuclei in an orderly manner.

7. A fully enclosed, explosion-proof, high-purity nitrogen-protected, three-in-one solid-liquid separator performs ultra-low temperature, ice-cold alcohol multi-stage washing: The precipitated crystal slurry is introduced into a completely enclosed "three-in-one" device under positive pressure dry nitrogen, where the mother liquor is rapidly filtered and separated, and the crystal surface is rinsed with ice-cold anhydrous ethanol online to remove trace amounts of entrained substances.

8. A high-vacuum, multi-layer rake-type continuous dryer forcibly removes residual intercrystalline encapsulated trace volatiles at room temperature and low pressure: The wet crystals are dried at room temperature in a completely light-proof and oxygen-free vacuum rake-type dryer. Continuous vacuum pumping keeps the material's moisture content firmly suppressed to the ultimate anhydrous limit of 1.0%.

9. Rapid mechanical pulverization and electrostatic-free precision granulation in an ultra-low humidity purified yellow light cleanroom (RH less than 10%): The dried rigid block crystals are rapidly pulverized in a strictly humidity-controlled, temperature-controlled dark chamber using a high-density granulator, resulting in uniformly dry particles of 80-100 mesh with an extremely narrow distribution.

10. Multi-layer inner filling high-purity gas barrier high-barrier aluminum foil bag vacuum double-layer heat-sealed and then placed in a moisture-proof steel drum for packaging: The granulated powder does not pass through any air and slides directly into the online weighing vacuum packaging machine. The double-layer heat-sealing prevents all external crystal water from seeping in.
