I have just started an extended fast (ideally 5 days, let us see if I can make it), water only, plus coffee and tea, plus minerals.
When I was losing weight, my doctor recommended me some minerals, including magnesium, sodium and calcium (but no potassium).
Now, I read some recommendations for extended fast, and I see that usually magnesium and salt (sodium) are recommended always, and potassium sometimes. But I never see calcium discussed.
I have salt and potassium-salt at home, and also good quality magnesium (several sources of magnesium). Am I set up with these? Or should I have some calcium, too?
