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). --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sc/products/774423008-alka-seltzer-extra-strength-heartburn-relief-effervescent-antacid-tablets-36ct](https://www.desertcart.sc/products/774423008-alka-seltzer-extra-strength-heartburn-relief-effervescent-antacid-tablets-36ct) --- *Product available on Desertcart Seychelles* *Store origin: SC* *Last updated: 2026-11-05*
