This Amazon product page sells Rejuvant Men's Calcium AKG Supplement, 1000mg, with 98% pure Ca-AKG (calcium alpha-ketoglutarate), in a 60-count bottle, described as the LifeTabs Original Men's Formula. The listing says the product uses a patented controlled-release formula and contains vitamin A. The 'About this item' bullets say the Ca-AKG formula provides clean and consistent support for healthy aging, that the controlled-release delivery is designed for gradual absorption and sustained cellular energy support through the day, and that the formulation was developed with aging researchers using clinically studied AKG science. The page says the men's product is formulated to support cellular energy, metabolism, and recovery for active men. It also says the product is produced in a third-party audited GMP-compliant facility and tested for purity, potency, and safety. Item details list the manufacturer as Ponce De Leon Health, the sold-by seller as Rejuvant, and the product benefits as anti-aging, increased energy and endurance, and reduced biological age. The recommended uses listed are supporting cellular energy, metabolism, and recovery, promoting healthy aging, and supporting muscle function and joint health. The page's item form field says Tablet, while the title says Capsules. The page also shows a bundle pairing this men's bottle with a women's Rejuvant AKG product.
