I recently had bloodwork as I suspected possible b vitamin deficiencies among other things due to symptoms I've been experiencing. Unfortunately I started supplementation with several vitamins including high doses of b12 for about a month or so prior to getting bloodwork, stopping the b12 about 2 weeks before and the rest about 1 week (in attempt to get as accurate of blood levels as possible). However much to my expectation my b12 was still elevated. The scale only went to 1200 which I maxed out. My mma was <.10 and homocysteine was 6.7 on a scale of 3.7-13.9. Folic Acid was 21.7. Does this rule out any chance of a functional b12 deficiency? Also, as mentioned I had not supped b6 in a week or more before my bloodwork. I was only using a combined total of 70 mg a day (50 synthetic before I knew better and 20 from p5p). However, my BW was still elevated at 134 on a scale of 20-125. I'm wondering if a functional b6 deficiency is possible as well. I read elsewhere that it is very rare to have elevated b6 levels using under 100 mg a day and I had only been using this dose for a little over a month and none for about a week prior to my bloodwork. Any thoughts on this? Right now I'm only taking 5 mg a day p5p in half a dose of the Thornes Multivitamin I got. However, I'm wondering if I shouldn't be taking more if there is a functional deficiency, yet at the same time am worried about worsening a potential overdose of b6 if there is not and my levels are simply too high.
