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.
