Thanks to reading information on this site and learning about what I can and can't do, I recently signed a form at my docs to ask for blood test results from the past 3 years. I received them yesterday and am horrified to see that, from May 2011 to last week, my folate has constantly been 5ng (3.00 - 20.00). The last test I had 2 weeks ago was 7ng (4.00 - 20.00) and yet I have been taking Spatone for over a month. I also eat liver at least once a week - what else can I do to raise it. My B12 is superb but as for my ferritin, in May 2011 it was 21ug (11.0 - 307.0) but it hasn't been tested since. I am concerned that this is all impacting on my Throid and really need to get these levels up.
