Getting the mineral in balance is another key aspect of healing candida. The yeast depletes magnesium, causing a deficiency, which in turns causes constipation + sinus issues. Yet your body needs magnesium, so it will go fetch some into your muscles when needed.
I have always preferred liquid magnesium to insure top assimilation, as well as Epsom Salt bath to promote its assimilation through skin pores. Mag citrate is not a bad option.
