Alka Seltzer Gold and brain fog

[Guest guest]

Dear friends,

Trying to find some relief to brain fog, it seems that alka seltzer

gold should be tried. However, in Spain it is not available. Moreover,

due to the rigidity of our customs, it doesn't seem easy to order it

from the US.

So I should try to find something more or less equivalent to it.

According to Alka Seltzer's web page, in one tablet of alka seltzer

gold there is:

Anhydrous citric acid 1000 mg. Antacid

Potassium bicarbonate 344 mg. Antacid

Sodium bicarbonate (heat-treated) 1050 mg. Antacid

According to AI (p. 148) the active ingredient of Alka Seltzer is

citrate. In this case, citrate = anhydrous citric acid?

Any other citrate will work as well, like sodium citrate or potassium

citrate?

Is important the specific combination of ingredients in alka seltzer gold?

For example, I have found a product (URALYT-URATO) used to dissolve

kidney stones whose ingredients are

Citric acid 18,44g/100g

Potassium citrate 81,46g/100g

Sacarine.

Should I try it?

Thank you in advance,
