Effervescence – What is it?
People ask all the time, "What is effervescence?" They've heard that term associated with Alka-Seltzer for years and years. Is it the bubbles? What makes the bubbles? And why do those effervescent bubbles work?
Yes, it's the bubbles! They're the result of a series of chemical interactions that break down the medicine after you drop the tablet in water. To learn more about those chemical reactions, visit our science experiment pages.
In the meantime, know that there are benefits to taking Alka-Seltzer® effervescent products. Effervescence refers to the unique and lively bubbling form that creates "The Alka-Seltzer® Experience." After dropping the tablet into water, you can rest assured that relief is on the way. The effervescent form, unlike a solid dose, allows for breakdown of the medication even before it enters your body. Simply put, the medicine dissolves fast and the antacid ingredients go to work instantly, neutralizing acid on contact.
Its effervescence is what makes Alka-Seltzer® special. In the words of one of our consumers: "I think Alka-Seltzer is a different kind of medicine because you can see, hear and feel it working. With the active and lively bubbles, Alka-Seltzer® speeds relief."
