for those of u who think betaine hydrochloride is the same stuff as i've been talking about, let me clear this up............it is not the same at all..........i took the betaine for over 8mos & it did very little for me...........when i talk about HCl, it is the actual chemical, not a powder.........i asked my dr what was the difference between the betaine & HCl...........he said, that if ur stomach was capable of making HCl on it's own, but for whatever reason, it isn't, then it will help..........BUT........& this is a big but........if ur stomach is incapable of making the necessary HCl, then u need the real stuff......i know that when i looked it up, everywhere i looked, they used both terms interchangeably..........& this is wrong..........very, very wrong......
