How does antacids effect stool color?

Antacids can sometimes affect stool color due to their mineral content. For example, antacids containing aluminum may lead to constipation, which can result in darker stools. Additionally, certain antacids that contain iron can cause stools to appear darker, while magnesium-based antacids might result in lighter-colored stools due to laxative effects. However, these changes are usually temporary and should resolve once the antacid is discontinued.
