No reason to fear this mineral while combined with all the other elements! Why are you using distilled water? Have you tested your tap water? A simple counter top filter. like Brita, may be all that you require and then you won't have to re-mineralize your water. I personally believe that distilled water should only be used for short period cleansing only, but most here on curezone believe otherwise. If you're up for reading I have posted many studies and articles regarding this issue in the water debate forum, in the end you must decide for yourself which is best.
