Which antacid would you pick if someone was complaining of acid indigestion and why?

For someone experiencing acid indigestion, I would recommend an antacid containing magnesium hydroxide and aluminum hydroxide, such as Maalox or Mylanta. These combinations effectively neutralize stomach acid, providing quick relief while minimizing the risk of diarrhea associated with magnesium alone or constipation from aluminum. They work rapidly to alleviate discomfort and can be taken as needed. Always consult with a healthcare professional if symptoms persist.
