Greetings, I followed RichV (so sad he is gone) protocol for 2 years with great success. I have homozygous C677T mutation, but I rallied anyway and I'm quite active. So, I stopped the protocol about a year ago. Fast forward: I had central air installed in my house and I believe it pushed the musty 70-year-old rockwall insulation in my attic into my living space--I have been sick ever since (6-8 weeks now). I'm failing daily. I had tests done, bloodwork generally ok, but sudden rise in glucose, iodine is low and my B12 IS OFF THE CHARTS HIGH! I'm having a company remove the offending insulation and replace it with environmentally sound stuff. Does anyone have an opinion as to the protocol--if I go back on it, do you think my B12 will go normal. I am taking absolutely NO b12 supplements, there is no reason on earth for me to have a 2000 pg/mL when the normal range is 211 - 946! Thanks you so much!!! Fire away---I'm listening!
