Low Vitamin D?
So, I started synthroid for hypothyroidism last July. At the same time I also was started on a megadose of Vitamin D, because I was below average at 19.
I was just re-tested, and now my vitamin D has fallen to 13!
I've been on vitamin D for months now. Is it possible my synthroid is interfering with the absorption? I'm only on 50mcg, although they're upping me to 75 this week. I make sure to take them at different times of the day.
I'm just confused over this turn of events. It just doesn't make sense to me. My doctor didn't say anything though beyond "you have to start another round of megadose treatment".
