Question: is bicarbonate of soda safe for drinking?
Answer: You can use it to: Calm indigestion: Add 1/4 teaspoon of baking soda to a glass of water to zap acid in your stomach. But acid doesn't cause all kinds of indigestion, so if your symptoms don't improve after 2 weeks, call your doctor. Don't take baking soda within 2 hours of other medications.
