<<Disclaimer: Verify this information before applying it to your situation.>> Does anyone have this? I didn't find anything in the archives but I think that I have seen something about it on the list in the past. I believe that it is caused by antacids. Have taken Mylanta Jellcaps for a couple years. Each caplet contains 550 mg Calcium and 125 mg Magnesium Hydroxide. It also contains Titanium Dioxide, which is a white powder. Could this be the Magnesium being deposited in my skin? Is there a way to find out? The deposits are large enough to be removed and analysed. Have been taking the jellcaps simply because it was the only antacid that I found that you could take without tasting the antacid. Junior Welch Rutledge, TN, USA
