Hello, Got some new lab tests done, quite comprehensive for a medicaid-based doc, but have a couple of questions. My b12 was high (Labcorp's range stops at "1999", and my result was ">1999". It doesn't of course say what form of b12. I was taking b12 shots, usually 3-4 times a week (with some gaps too) for the last 4-5 months. RBC folate was low, which I guess isn't a surprise, but kind of nice to see validated on a medicaid panel. It was 435. Their range is 468-1258. I wasn't taking too much methylfolate, as I wasn't sure if it was causing havoc or not. I don't think it was, because there were some days when I took it for 2-3 days (in small amounts) and felt a little stronger, and more hopeful -- but not sure, so I didn't take it regularily. The odd result was that my urinary MMA was 'low-normal' at 3.7 (the normal range for labcorp is 1.6 - 29.7). They also listed a "MMA-Normalized" result of 1.0, with the normal range being 0.4 - 2.5 -- I'm not sure what that means. But I had to convince her the MMA test was critical, so now that it's 'normal' she's suggesting I need to stop the b12 (which I did 2-3 weeks back), and increase my folate. (She was always skeptical of the b12 issue, but I finally brought in studies from journals she accepts.) SO...questions: Does too much b12 lower folate levels? Or...do you think this is mainly due to not getting enough folate regularily the past year? (My methylation panel had low folates as well.) If I increase the folate, which I'm starting to do with small amounts of folinic (then will start methylfolate in a couple weeks), would it be prudent to do a b12 shot say once a week? Not sure what to make of the MMA situation. THANK YOU, Dan p.s. Still lots of anxiety, stress intolerance, but another specialist I'm working with says that's due to erratically high-ish (then low AM) cortisol -- adrenal burnout.
