The main thing to look for when taking baking soda for your health is to make sure it doesn't contain aluminum. There are a number of excellent articles online Re: the health benefits.
Here is one if you'd like to take a look. It's always best to do your research before accepting other peoples recommendations, so that you have confidence when introducing it into your diet. I know my grandmother used to take a tsp in water whenever she had heatburn.......which is a sign of an acidic digestive system. She generally experienced quick relief soon after drinking it.
I like to add lemon or lime juice to mine to disguise the taste of the baking soda. Just a personal preference. I'd start with half a teaspoon before breakfast but it is always best taken on an empty stomach which because it corrects the PH balance before eating.
