Introduction

Calcium Alpha-Ketoglutarate is a mineral-organic acid complex formed by the chelation of calcium with alpha-ketoglutaric acid, a naturally occurring dicarboxylic acid that plays a central role in the citric acid (Krebs) cycle. As a Krebs cycle intermediate, alpha-ketoglutarate is essential for aerobic energy production and serves as a nitrogen transporter in amino acid metabolism. The calcium salt form provides both the metabolic benefits of alpha-ketoglutaric acid and supplemental calcium in a single compound. Ca-AKG has gained attention in sports nutrition and recent research has explored its role in longevity and healthy aging pathways.

Uses

  • Sports nutrition supplements for energy metabolism and endurance
  • Pre- and post-workout formulas for muscle recovery
  • Anti-aging and longevity supplement formulations
  • Dual-purpose calcium and metabolic support ingredient
  • Amino acid metabolism support supplements
  • Functional food products targeting athletic performance
  • Clinical nutrition for nitrogen balance support
