<<Disclaimer: Verify this information before applying it to your situation.>> As many celiacs are deficient in iron and zinc at diagnosis, I realized that you might enjoy an article I have been working on for several years. I call it "The Penny Sniff Test" and describe many symptoms of low metals and also of their interactions. It's fun to play with anyway, preferably in a group. It's too long to post here, so you will have to email and ask me for it. I might take a few days to send them all out, even a week. If any of you missed my similar offer for the Taste Tests, for electrolyte self testing, you can ask for that too. Donna * All posts for product information must include the applicable country *
