Key Benefits
DoNotAge Ca-AKG provides calcium alpha-ketoglutarate, a compound involved in normal biochemical processes in the body. AKG is naturally present in the Krebs cycle, where it plays a role as an intermediate molecule in cellular metabolism. This formula combines AKG with calcium to create a stable, easy-to-mix powder. It contains no fillers or additives and is suitable for vegan and allergen-free diets. Each batch is third-party tested for purity and consistency, offering a clean way to include Ca-AKG in a daily routine.
