Are you taking a multivitamin? I too have had high vitamin B on my labs for the last 2 years during periods of time where I stopped my multi vitamin. I have found the most vitamins have well over the recommended daily allowance of B vitamins. I have had two instances a couple of years appart where I was taking a multivitamin (one had 400% and the other 800% of the daily allowance) and I had to stop taking them because my blood pressure was high, ringing in my ears, I was having trouble sleeping, and I was anxious. I have just asked my Dr. to repeat the test again. I think if it is high again, I will need to find answers if B can store in your body for long periods of time.
