Thats what I'm talking about. One more thing: If I have powder with calcium, magnesium, potassium carbonate, can I mix it with ascorbic acid powder to make a drink? I've done it once and it tasted quite good, didnt give me the symptoms I get after only mixing vit c powder and water, and it fizzled a litle which was cool. I dont know whether it affects any of the two in any way for them to be less potent.
