Hi again, my daughter complains about major calf cramping and it comes to me more and more about the potassium deficiency that many of us could NOT be dealing with. I just posted a Potassium RDA on the vit/herb section here. I've been nagged by this potassium issue for a long long time. I take extra potassium but will be taking more daily. Now IF one can get it in foods, that's great, but I don't feel it's possible to get the daily RDA. And we're not going to get this info from conventional MD's.
