Echo Water (echowater.com) is a US-based company specializing in molecular hydrogen water technology -- products that infuse regular drinking water with dissolved molecular hydrogen (H2) gas at therapeutic concentrations. Founded on the emerging science of molecular hydrogen as a health intervention, Echo Water has built a comprehensive product ecosystem ranging from portable flasks and countertop pitchers to under-sink machines, whole-home systems, and professional hydrogen water servers.

The scientific case for molecular hydrogen is more substantial than most people realize. Since 2007, when a landmark study published in Nature Medicine demonstrated that inhaled hydrogen gas could selectively reduce cytotoxic oxygen radicals while preserving beneficial reactive oxygen species, over 1,500 peer-reviewed studies have been published on molecular hydrogen's biological effects. The evidence is strongest for hydrogen's selective antioxidant properties -- unlike broad-spectrum antioxidant supplements that neutralize all reactive oxygen species including beneficial ones, molecular hydrogen specifically targets hydroxyl radical (the most damaging ROS) and peroxynitrite while leaving other signaling ROS intact.

Echo Water's products generate hydrogen-rich water through a process of water electrolysis -- applying electrical current to water to generate dissolved H2 gas at concentrations of 1.5+ parts per million, the threshold at which biological effects become measurable. The Echo Pitcher, H2 Flask, and other portable products provide an accessible entry point, while the Echo H2 Machine, Echo One, and RO systems provide whole-home or continuous-use hydrogen water for committed users.
