Hello,
How do you prepare your coffee. Just regular boiling extracts almost no magnesium and niacin, even not very much caffeine. Espresso does the job, steaming hot water under pressure extracts even as much as 50mg magnesium per 100 ml. But you have to have the espresso machine. Instant coffee is a problem because all of the ground coffee seeds remain and that has a lot of oxalates.
The second problem are oxalates, I am not sure how much of them are in espresso, but boiled is very low. the question about magnesium is, that it is probably most of it in form of magnesium oxalate and not very bioavailable. Is coffee really usefell as magnesium source and should we use it only as a caffeine source and only boil it?
