@terri, I went to see a neurologist for my feet. She gave me a blood test, including vitamin B 6. Turns out my b6 level was so high it was toxic. It takes a year or two to eliminate...it is not soluble and gets stored in muscles. She told me to check labels, especially energy drinks which almost always have a lot of B6. That was about 7 months ago. I had a recent test; had to be sent to a lab in Virginia as B6 testing is not a routine blood works test. Three weeks later I got the results. I think a normal range was like 1.2 to 2.1...mine was 126. Really high. I'm wondering what a B protein is. High B6 is one of the causes of peripheral nephropathy. My primary doctor, very knowledgeable
had never herd of B6 toxicity. Just wondering if any Mayo buddies have vitamin or protein problems. Flib
