I think my doctor runs on her own normal levels even at 13.4 ng/ml she wouldn't supplement me. I immediately bought high dose D3 5000IU which I have taken on and off since then. I haven't taken it for a few days and the muscle aches are going, so I must be sensitive to it. Will have to rely on the sun, hopefully! I've had my amalgams out it was no problem the dentist was amazing. Now waiting to see a doctor who specialises in people with hashi's and problems like mine.
