Alpha-Ketoglutarate Acid (AKG) CAS 328-50-7 | Reliable Export Grade Raw Material Supplier

Introduction

Alpha-Ketoglutarate Acid (AKG) is a high-demand biochemical raw material widely used in global sports nutrition, biochemical testing and pharmaceutical synthesis industries. With superior bioavailability, stable aqueous properties and non-toxic characteristics, 2-Ketoglutaric Acid is extensively applied in functional foods, dietary supplements, liver function testing reagents and organic synthesis intermediates. We supply premium export-grade Alpha-Ketoglutarate Acid with consistent batch quality, anti-moisture packaging for ocean shipment, complete export certificates and free sample support for worldwide bulk orders.

Why Global Buyers Prefer Alpha-Ketoglutarate Acid (AKG)

Compared with similar metabolic raw materials such as glutamic acid and glutamine, AKG delivers higher bioavailability inside the human body.

Only around 40% of ingested AKG gets rapidly degraded during metabolism, while the remaining portion continuously supports intestinal repair, cellular metabolism and amino acid synthesis. It serves as an ideal ingredient for post-workout recovery, fitness nutrition and enteral nutrition formulas.

In addition, Alpha-Ketoglutarate Acid features stable aqueous solution and excellent safety profile, making it perfectly suitable for long-term formula development, mass production and long-distance cross-border shipping. It has become a repeatedly ordered staple raw material for overseas health brands, laboratories and chemical traders.

Main Application Fields of Alpha-Ketoglutarate Acid

2.1 Sports Nutrition & Dietary Supplements

As a popular nutritional fortifier, it is formulated into fitness powders, recovery supplements and functional energy drinks to boost energy metabolism and physical rehabilitation, a top-selling ingredient across Europe, America and Southeast Asia.

2.2 Biochemical Testing & Laboratory Reagents

Alpha-Ketoglutarate Acid acts as a specific substrate for liver function tests, applied in the detection of transaminase and dehydrogenase. It is also used for tryptophan analysis and biological experiment reagents, an essential stock material for research institutions and testing enterprises.

2.3 Pharmaceutical & Fine Chemical Intermediates

As a key metabolic intermediate, it is adopted in multiple pharmaceutical synthesis and biochemical manufacturing processes, customized for pharmaceutical R&D and fine chemical production.

2.4 Food Additive Raw Material

Food-grade AKG can be formulated into a wide range of functional health foods, complying with food additive standards for most international markets.

Our Core Advantages for Export Supply

Three major concerns bother most international importers when sourcing AKG: moisture absorption during ocean transit, inconsistent batch color, and incomplete documents for customs clearance. We have fully optimized our supply chain to address these challenges.

3.1 Custom Moisture-Proof Packaging for Ocean Transportation

Against the hygroscopic nature of AKG, we adopt double-layer sealed moisture-proof packaging tailored for high-humidity maritime environments, effectively preventing caking and yellow discoloration during long-distance shipment.

3.2 Strict Batch Consistency & Quality Control

A standalone COA certificate is issued for every batch, with precise control over purity, moisture content and appearance to support long-term stable repeat orders.

3.3 Complete Export Documentation for Global Customs Clearance

We can provide full sets of trade documents including MSDS and COA to assist smooth customs clearance in different countries.

3.4 Ample In-Stock Inventory & Flexible MOQ

We accept trial sample orders, small-batch pilot runs and full-container bulk shipments to accommodate new and regular clients with varied procurement demands.
