If they were really low then you may need a round of weekly high dose pills for a few months before starting supplements. I had to do that at first for I think 6 months. Now I keep supplementing and still am on the lower end because I am inside so much of the summer because of heat intolerance from meds and then not as much in winter because it is winter. I need to remember to have him check that next week; I think he forgot when we did my annual labs.

It made a big difference for me when I got it straightened out. Not like I was cured, but I did feel better.
