Ca-AKG is the calcium salt of alpha-ketoglutaric acid (AKG), a key intermediate of the human mitochondrial Krebs cycle. It appears as white crystalline powder with purity ≥99%.
Compared with free AKG, Ca-AKG features superior stability and intestinal bioavailability, delivering sustained absorption of AKG plus supplementary calcium.
