What’s the difference between Alka-Seltzer effervescent tablets and ReliefChews?

Both effervescent tablets and ReliefChews are portable and deliver fast multi-symptom relief. Effervescent tablets dissolve in water for fizzy, refreshing relief you can hear, see and feel. ReliefChews are delicious and chewy.

What temperature of water should I use to dissolve Alka-Seltzer tablets?

The best temperature is room temperature. Cold water will slow down dissolution and warm water can make it foam excessively.

Is Alka-Seltzer the same as baking soda?

Not exactly. Baking soda (sodium bicarbonate) does not contain anhydrous citric acid, the main active ingredient in Alka-Seltzer effervescent tablets that relieve heartburn and acid indigestion.

What makes Alka-Seltzer fizz?

Alka-Seltzer contains citric acid and sodium bicarbonate (baking soda). When you drop the tablet in water, the acid and the baking soda react – this produces fizz.

What are the active ingredients in Alka-Seltzer ReliefChews?

ReliefChews contain calcium carbonate (antacid). Heartburn+Gas Relief Chews contain calcium carbonate (antacid) and simethicone (antigas).
