baking soda is sodium bicarbonate, which is sodium and carbon. this is not such a good idea as most americans have plenty of sodium in there bodies already. sodium and potassium are antagonists and need to be balanced in relation to each other, using baking soda will raise your sodium level but not your potassium, thats not good.
you may want to get some 100% pure coral calcium, it has calcium magnesium and trace minerals. i use it everyday, and like it quite a bit. if you put some of that in a cup and add lemon juice it fizzles right up, this is the chemical reaction that is so good for you. but make sure it is 100% pure with no additive or fillers.
but i still think the bs mollases is great and use that also. it is high in potassium phosphorous and many other key minerals that are hard to come by in other foods.
