Product Parameters

Product Details

1. Overview

L-Alpha-Glycerylphosphorylcholine (Alpha GPC) is a water-soluble choline phospholipid derivative that occurs naturally in small amounts in animal and plant foods. It is a biosynthetic precursor to acetylcholine and phosphatidylcholine, and has been studied in research models for its roles in choline metabolism and phospholipid synthesis. Knowlux supplies Alpha GPC as a research-grade material for laboratory and analytical use. L-alpha-GPC was approved as a new food raw material in China in 2024; this regulatory status is separate from this research-grade supply.

2. Research Context (Not a Therapeutic Claim)

Published literature describes Alpha GPC as a choline derivative studied in in vitro and in vivo research models, with proposed roles in acetylcholine synthesis, phospholipid metabolism and cellular membrane function. These descriptions are derived from published research and are provided for scientific reference only. Knowlux makes no claims regarding the efficacy, safety, or suitability of this product for any human or veterinary application. Promotion of Alpha GPC for cognitive enhancement, memory improvement, nootropic use or athletic performance is not supported by Knowlux and is inconsistent with research-use-only supply.

3. Quality Control

Full COA, MSDS, and lot-specific chromatograms are issued with each shipment.

4. Applications

• Reference standard for analytical method development

• In vitro choline metabolism and phospholipid synthesis studies

• Research on acetylcholine precursor pathways and membrane biology

• LC-MS and biochemical assay calibrators

5. Packaging, Storage & Shipping

Powder: amber glass vial or high-barrier foil bag under nitrogen headspace, sealed with tamper-evident closure. Secondary packing: light-protected carton with desiccant.
