EMF exposure is a real thing these days, and compromises cellular function. The more I research this subject, the more concerned I am. There is a lot of useless crap on the market being sold as "EMF protection." If I have added the products to this page, it means there has been extensive research into the efficacy of the product and has been tested with meters. These Colloid crystals are considered some of the most effective tools for reducing EMF exposure as they carry moisture content and magnetic properties that significantly repel EMF.
