I have a further query about potassium - my reading indicates that potassium can be absorbed by the body from most «potassium salts» so I have been testing «Cream
of Tartar» - I add a 5 gram sachet to a
large glass of cold water - which gives it a very slight sour taste (not unpleasant at all)- you need to stir it, as the «salt» does not really dissolve.
