Thank you so much for the information you provided regarding Vitamin B12. I have never, at least that I know of, had a B12 test. What is involved in testing for B12? I’m beginning to wonder if having hypothyroidism has something to do with loosing our taste/smell. I met someone last year on vacation that was gaining weight fast, as I was, and had lost her taste/smell as well with Covid. She was also diagnosed with hypothyroidism. As we know, hypothyroidism slows our systems down, so could be the reason it’s taking so long to come back. I’m guessing at this point, but it makes sense to me.
