My doctor has been following my b6 levels after I tested toxic back in Feb. Another doc had put me on Mega doses (B-100) and I became toxic. I went off of that supplement and take a multi-vitamin that has 5mg of B6 (it s New Chapter whole foods based multi) and I am still testing in the high range, though not toxic. She wants to test me again in 3 mos. I am 60 yrs. old, hypo-thyroid, have high cholesterol, GERD, and have a slight fatty liver, though I have lost 27 lbs in the past year and a half. I teach fitness classes so I m in relatively good shape. Is there any condition that would cause my B-6 levels to stay elevated?
