An EMF Ion Glass Defense Pendant is a type of necklace that deflects and neutralizes EMF radiation. Plus, negative ions are believed to have several benefits, including helping to improve mood, increase energy levels, and purify the air. These pendants are designed to be worn close to the body so that the negative ions can be released directly into the bloodstream. Ion Glass Defense Pendants have been shown to be effective in reducing EMF exposure. People who wore a glass pendant had significantly lower EMF exposure than those who did not wear one. It’s also found that these pendants were effective in reducing the negative effects of EMF exposure on the body, including fatigue, headaches, and many other symptoms.
