no antacid is worthwhile they have bad side ingredients.
powdered calcium in warm distilled water is milk like in flavor with a bit of chalky mouth feel.
it is basically a fully purified tums or rolaids antacid tablet in warm liquid form
far better then using pepto bismal or rolaids or tums or any flavored knock off.
it is a patch for relief not a cure. you need to find out why the acid leaks out.
a lot of possible reasons.
No-one likes to hear it but this is the cure.

Not if you are an active diabetic.
The muscle controlling the flap weakens and acid ,bile,pepsin along with capsicum leaks out . making standard heartburn seem like a relief. actually the reflux i got with hot peppers is one of a few reasons i figured out i had diabetes.
