1. What Is Glycine Alpha-Ketoglutarate?

Glycine Alpha-Ketoglutarate (GAK) is a stable molecular complex formed from the amino acid glycine and alpha-ketoglutarate, a naturally occurring intermediate in cellular metabolic pathways. In industrial applications, GAK is valued for its high bioavailability, formulation compatibility, and stability, making it suitable for powders, capsules, tablets, and functional blends.

From a formulation perspective, GAK serves as a nutritional support ingredient rather than a pharmaceutical substance, and is commonly used where amino acid supplementation and metabolic intermediates are required.

---

4. Mechanism of Use & Functional Characteristics

(Non-Therapeutic, Scientific Description)

From a biochemical perspective, GAK combines:

• Glycine, a conditionally essential amino acid used in protein synthesis

• Alpha-ketoglutarate, an intermediate involved in cellular nitrogen and carbon metabolism

In formulated products, GAK is used to:

• Support nutritional amino acid supplementation

• Serve as a functional component in sports and performance nutrition

• Enhance ingredient compatibility in complex formulas

No disease prevention or treatment claims are made or implied.
