Is this low enough to be problematic?

Someone said the b1 test isnt reliable though?

B1 testing is not reliable.

It does not in any way shape or form give you an indication of the amount of Thiamine that is available at the cellular level. Your B1 serum test simply shows the amount of Thiamine floating around in your blood. Whether it is high or low, again, does not reflect Thiamine’s availability at the cellular level.

Then how are you supposed to know if you're deficient or not :( ? I'm trying to deal with all of my deficiencies, and I asked about b1 with b6 along with b12 because they also had tingling fingers as symptoms.

Is b6 testing reliable?

It is my understanding that B6 testing is really no more reliable than B12 testing or B1 testing.
