Calcium alpha-ketoglutarate (Ca-AKG) is a calcium salt of alpha-ketoglutarate, a key intermediate in the Krebs cycle involved in cellular energy production. It gained attention in the longevity space after a 2020 mouse study showed significant lifespan extension and reduced frailty. AKG levels naturally decline with age, and supplementation aims to restore them. Human clinical trials are still in early stages. The "calcium" in Ca-AKG refers to the mineral salt form, not an additional calcium supplement — though it does contribute a small amount of dietary calcium. Products below are ranked by cost at your chosen daily dose.
