What is an ionic bracelet? It sounds like it came out of a sci-fi film, but it really is a bracelet used to improve one’s health through negative ion therapy. This is a type of therapy that exposes a person to an environment that’s filled with negative ions. An ionic bracelet goes by many names: ionic wristband, ionized bracelet, negative ion bracelet, balance bracelet, or wellness bracelet. All of them could refer to the same thing.
