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.

Ca-AKG is the calcium salt of alpha-ketoglutaric acid (AKG), which is a key intermediate in the human mitochondrial Krebs cycle. It appears as a white crystalline powder and is widely used for longevity and nutritional supplement formulations.
Compared to free AKG, Ca-AKG offers superior stability and higher intestinal bioavailability. This ensures sustained absorption of AKG by the body while simultaneously providing supplementary calcium.
Ca-AKG is commonly used in anti-aging and longevity dietary supplements (often combined with NMN and resveratrol), sports nutrition for muscle gain and recovery, and bone mineral density support formulas for the elderly.
Our Ca-AKG has a high purity specification of ≥98.0% (with actual results testing at 99.6%). It complies with rigorous safety standards, showing heavy metals under 10ppm and zero presence of pathogens like E. Coli, Salmonella, and Staphylococcus Aureus.
For smaller quantities of 1kg, we pack it using double plastic bags with an aluminum foil bag inside and a box outside. For larger bulk orders of 10kg, 25kg, or more, it is packed inside sturdy drums or cartons with two layers of plastic lining.
We support shipping via major express carriers (DHL, FedEx, UPS, EMS) for door-to-door delivery within 3-7 days. Larger volumes can be shipped by Air (3-7 days to airport) or by Sea (10-35 days to port) depending on order requirements.
