I use to buy the original fruit flavored tums that were 500mg. I never was too fond of the flavor, especially if I was nauseous, the flavor of the original would actually make it worse. I never felt they they helped that much. I only could feel a very small difference. I gave these 750mg tums a try, to see if the flavor was better. The strange thing is, I can take one of the extra strength smoothie and they have worked so well for me! And let me tell you the taste of the smoothie tums are sooo delicious! They don't even taste like a typical tum. If you feel like tums don't work that well for you or your not crazy about the taste - definitely give the smoothie extra strength a try!!
