I did this on several people's suggestion, including @Sushi, @Gondwanaland, @adreno. Just got my results: Vit. D 25-Hydroxy 53.4 ng/mL [range 32-100] Calcitriol 1,25 di-OH 103.1 pg/mL [range 10-75] At this point, I have stopped all oral vit. D (over a month before this test), and I've been taking a daily dose of 3,000 iu in my transdermal B12 oil. That's it. I have VDR Bsm +/+, like @Sporty, who had a thread about feeling worse on vit. D. And @Valentijn warned me that VDR Bsm does not really have a big effect on Vit. D retention. This article calls my situation "Dysregulated vitamin D metabolism": https://chronicillnessrecovery.org/index.php?option=com_content&view=article&id=176 So I see that it can aggravate my Hashimoto's, and it can increase inflammation (which I have). Would this also raise my EBV antibodies? They are in the stratosphere.
