This is my second order of the Ionic Lytes Electrolyte Concentrate. As I move through a weight loss phase, my body needs to efficiently hydrate to keep up with my activity and reduced calories. I like the mineral content of this concentrate and how easy it is to shake and squirt onto my water bottle as I need it. I highly recommend shaking each time. The sodium does begin to crystallize and concentrate toward the end of the bottle. Be prepared to add water directly to the bottle and dilute in a separate glass/bottle of water to finish the product.
