Description

Calcium 2-Oxoglutarate is the calcium salt of 2-oxoglutaric acid, a key intermediate in the Krebs cycle. This compound is valued for its role as a metabolic enhancer and a stable source of α-ketoglutarate (AKG). It is primarily utilized in the formulation of dietary supplements, sports nutrition products, and clinical nutrition solutions. Its stability and bioavailability make it a critical ingredient for manufacturers targeting metabolic health and cellular energy support.

Application

• Dietary Supplements & Nutraceuticals: Used as an active ingredient in capsules, tablets, and powders designed to support energy metabolism, athletic performance, and recovery.
• Clinical & Medical Nutrition: Incorporated into specialized enteral and parenteral nutrition formulas for patients requiring metabolic support or recovering from surgery.
• Sports Nutrition: A key component in pre-workout and post-workout formulations aimed at enhancing endurance, reducing muscle fatigue, and promoting nitrogen balance.
• Cell Culture Media: Serves as a component in specialized cell culture and fermentation media, acting as a metabolic precursor.
• Pharmaceutical Intermediates: Employed as a starting material or intermediate in the synthesis of more complex pharmaceutical compounds.
• Research & Development: Used in biochemical research to study cellular metabolism, mitochondrial function, and amino acid synthesis pathways.
