Celliant is a patented technology that utilizes a blend of 13 thermo-active minerals—including titanium dioxide, silicon dioxide, and aluminum oxide—and proprietary ingredients that can be embedded into the core of a yarn. According to Celliant’s website, the embedded minerals convert the body’s natural energy into infrared light, which is then absorbed into tissues and muscles. This then causes the body to increase circulation and oxygen, which can lead to superior muscle performance, faster recovery from physical activity, improved thermal regulation, and a more restorative sleep. Celliant can be applied to a wide range of fabrics, including athletic wear, bedding, insulations, and furniture, and cannot wash or wear out as the technology is embedded into the core of a fabric’s fibers.
