IP-6 is a new one for me! Thanks for the info, I shall look into it. Yes, I am using Sea Salt . Not Celtic, but Mediterranean. The vitamin C info is interesting. Sometimes it is hard to know when to cool it on vitamins excreted by the kidneys, and when to up those vitties. Good to know C is OK in large amounts. I had been sticking to the C in juice, and drinking lots of it.
