I have done two full thyroid panels with Blue Horizon, 16th months apart, the most recent being November ‘23 and I would appreciate your insight and advice.
B12 and folate were low in July ‘22 so I took Thorne Basic B for about 6 months at the beginning of this year. My energy improved and my hair got much better. Recently my hair has been thinning again so I thought I would retest and then restart the supplement.
I am confused by the fact that the reporting has changed from B12 to B12-Active, with a different range. I now seem to be at the top of the range of B12-Active, so should I not resume supplementing?
The results are:
July 22
Vitamin B12: 218 (145-569)
Serum Folate: 12.6 (8.83-60.8)
November 23
Vitamin B12- Active: 148 (37.5-150)
Serum Folate: 22.4 (8.83-60.8)
For the record my thyroid was removed in March ‘22 and I am on 125mcg levo.
Thank you so much for any advice you may be able to offer.

Igennus B complex popular option too. Nice small tablets. Most people only find they need one per day. But a few people find it’s not high enough dose
IMPORTANT......If you are taking vitamin B complex, or any supplements containing biotin, remember to stop these 7 days before ALL BLOOD TESTS , as biotin can falsely affect test results
In week before blood test, when you stop vitamin B complex, you might want to consider taking a separate folate supplement (eg Jarrow methyl folate 400mcg)
