I think that the Tums work for indigestion. They provide almost instant relief in a secrete way. It's great not to be embarrassed when I get indigestion. I just pop in a "mint" and my problem is solved. I also like that the product isn't chalky. I hate the chalky ones because they taste bad a make a mess. With these my hands stay clean. One thing is that the "freshers" part doesn't work. These Tums don't freshen my breath at all. But, they do have a lot of other great feature that make up for it. Effectiveness The Tums are extremely effective for indigestion. The problem goes away almost instantly. They however don't get rid of bad breath. Ease of Use These Tums are super easy to use, you just pop one in your mouth. The product is about they size of a mint. Immediacy The product works almost instantly. It like as soon as I swallow it my indigestion is gone. I really like this for when I need fast relief for my indigestion.
