I have given her some 5000 IU vitamine D, which if taken daily gets up to the 50,000 per week. Gave her some
calcium and a good multi-vitamine also.
And yes, she should take Synthroid, but her Ukrainian doctors are mis-advising her, saying that her lab results are "in range" even if they are all on the absolute low of the range. I think the Synthroid would help her absorbe the calcim.
She has gotten very bad advice, and she will suffer forever because of it.
