Fascinating. Thank you.... Probably should start a new topic on several issues from that link..
But lets consider the 4,700 mg daily requirement for adults?
If a banana contains 422 mg, then to get adequate potassium in the diet, we'd have to eat 10 bananas per day or the equivalent? It is hard to imagine we generally get that much potassium from the diet.
And since supplements are limited to 99 mg (which seems to imply danger at higher amounts... Yes, I know the real reason..) something seems askew.
But this is great information, and probably something anyone with high blood pressure should try.
I also note that low magnesium can lead to low potassium levels, according to LPI.
