Effervescent tablets dissolve in water for fizzy, refreshing relief you can hear, see and feel. ReliefChews are delicious and chewy. **Q: What temperature of water should I use to dissolve Alka-Seltzer tablets?** A: The best temperature is room temperature. Cold water will slow down dissolution and warm water can make it foam excessively. **Q: Is Alka-Seltzer the same as baking soda?** A: 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. **Q: What makes Alka-Seltzer fizz?** A: 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. **Q: What are the active ingredients in Alka-Seltzer ReliefChews?** A: ReliefChews contain calcium carbonate (antacid). Heartburn+Gas Relief Chews contain calcium carbonate (antacid) and simethicone (antigas). ## Frequently Bought Together - Alka-Seltzer Heartburn Relief Extra Strength Effervescent Tablets, 4-in-1 Relief from Heartburn, Sour Stomach, Acid Indigestion, and Upset Stomach, Dissolvable Antacid, 24 ct - Alka-Seltzer Effervescent Tablets Original Flavor, Fast Multi-Symptom Relief from Headache and Body Ache, Dissolvable Effervescent Fizzy Tablets, 72 Ct --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.ar/products/365987493-alka-seltzer-extra-strength-heartburn-relief-effervescent-antacid-tablets-fast](https://www.desertcart.com.ar/products/365987493-alka-seltzer-extra-strength-heartburn-relief-effervescent-antacid-tablets-fast) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-09-12*
