Can anyone tell me what is considered a low sodium mineral water? I much prefer drinking sparkling water but know it should be low sodium. However there is such a huge variation in the amount of sodium in the waters available. The one I'm using now from Lidl the Saskia classic is 13.8mg/l of sodium which is the lowest of the ones they do but just read an article that says ideally it should be less than 10mg with a high calcium and magnesium content. Should I be looking for a lower sodium water? I've basically got nowhere with the diet since the initial attack phase drop and am trying to find reasons for that. Thanks.
