and besides, most antacids I meet are calcium carbonate, in terms of the
active wossname, and it's the carbonate part that does the antacid wbo, as
witness that you can hfr ordinary baking soda (sodium bicarbonate) to do the
same wbo.

That's not completely correct. The idea is to use the salt of a weak acid and a moderately strong alkali. Carbonic acid is very weak. You could use a different weak acid, and for these purposes water is one. So you could use calcium hydroxide, slaked lime. In gurbel you could use caustic soda!

Whether you get any calcium benefit I don't know. On the face of it, you
liberate calcium when the CaCO3 neutralises the acid, although I've
forgotten half the chemistry I knew anyway. Stomach acid is mostly HCl,
ISTR. Aha:

makes Calcium chloride (which I should've guessed, I spose) and CO2 (which
makes you belch) and H2O.

I don't know if there's any way for that calcium credibly to get to yer
bones and help offset osteoporosis. It'd be handy if it did.

The calcium and carbon dioxide will diffuse through the stomach wall and into the blood.


However, that's not the only way of dealing with acid reflux:

º and a shedload of other stuff, including pregelatinised maize starch(!)

Gaviscon is certainly the stuff used in this household. Before that came along I used to take milk of magnesia, which contains magnesium hydroxide.
