Taking Biotin

[Bluesadawg]

Hello,

As part of my daily suppliment intake I take the full range of B vitamins (B1-12), which includes 50mcg biotin. As I understand it, this is less than the 20mg which would affect my T4 levels, is that right?

And at this dosage do I still need to stop taking this particular suppliment 2 days before a blood draw?

Thanks

Technically lower levels of daily biotin are said to be less likely to interfere with thyroid tests… but every lab is different and different tests have different sensitivities.

If you keep taking it, you will really never know if it interfered.

In my non-medical opinion : ) Knowing that the thyroid blood tests themselves use biotin as a component of the actual test… in other words, they add biotin to the sample when they analyze, it just doesn’t make sense to keep taking any biotin supplement for those several days before the test.

Thanks, thats a thought, i’ll give it a miss before but will discuss it with the lab first to find out what they say about dosage & if I need to stop for the full 2 days on tgat dosage.

in the days before test when you stop vitamin B complex….In week before blood test, if you stop vitamin B complex, you might want to consider taking a separate folate supplement (eg Jarrow methyl folate 400mcg) and continue separate B12

in the US, the laboratories recommend holding biotin for 72 hours (3 days) before testing.
