Question: is baking powder and baking soda gluten free?
Answer: What about baking soda? Baking soda is naturally gluten-free, as the leavening agent is just bicarbonate of soda. If you're substituting baking soda for baking powder then remember to triple the amounts. So, if the recipe asks for 1 tsp of baking soda, you'll need 3 tsp of baking powder.
