well thats good you found some with no aluminum. if they are finding no issues in your belly what kind of symptoms are you having that made you have the endo's ?? maybe a little tweak in your diet and adding some aloe juice and ginger tea and maybe every the celery juice might do the trick for you. it sure has helped me a ton. first time in 40 years i have not been on any meds for my gastric issues. im 64. you know now that i think about it its not the antacids that have aluminum its the baking soda but you can buy aluminum free.
