I have GERD, Vegan and I want to take multivitamins& minerals, omega 3, iron b12 and calcium and vitamin D. Will my GERD become worse?

Your doc can give. You something for it after he/she diagnoses it. You can also use dgl, available in the health food store. These capsules are licorice w/out an enzyme that raises blood pressure. They coat the lining of esophagus. Peace and good health. Apple cider vinegar is fine bt please make sure you use the "with the mother" on the label (peelings). Dilute w/water. Peace and good health..
