I've taken apple cider vinegar (organic with the "mother") for about 10 years now for a variety of reasons. I too had breast calcifications and they are now gone for several years now (not sure exactly how many).
I take 1 tablespoon in about 10 to 12 ounces of water in the mornings, about 5 mornings per week, first thing on an empty stomach. After a few months, I added about 1/2 teaspoon of baking sofa to the mixture to help with constipation. I also take about 1/2 teaspoon of apple cider vinegar with a pinch of baking soda in 6 ounces of water at bedtime for indigestion (about 5 out of 7 nights).
I do take some other supplements, but I believe the breast calcifications disappeared with the apple cider regime.
Apple Cider Vinegar for Breast Calcifications
This is belated THANK YOU to Earth Clinic and those who share on the site. In Dec 2014, I posted that the doctor found calcification in my breasts after a regular mammogram. I read here that Apple Cider Vinegar destroys calcification and went about taking it as advised on this site. Well, I went for a second mammogram in early Jan 2015 and NO calcification was found!! Praise God and thank you Earth Clinic!
