Baking Powder

Baking powder increases the volume and lightens the texture of baked goods. It's a dry leavening agent made from a mixture of carbonate or bicarbonate, a weak acid, and a filler. When combined with liquid, the baking powder creates an acid-base reaction, which releases carbon dioxide gas into the batter or dough.

Adverse Effects

The amount of baking powder used in cooking or baking is considered safe. However, serious complications can arise from overdosing on baking powder. Side effects of baking powder overdose include thirst, abdominal pain, nausea, severe vomiting, and diarrhea.

The bottom line

While both products appear similar, they're certainly not the same. Baking soda is sodium bicarbonate, which requires an acid and a liquid to become activated and help baked goods rise. Conversely, baking powder includes sodium bicarbonate, as well as an acid.
