My dr checked this at my annual appointment this year and mine is way way way low! 😦
Now I’m taking 100,000 IUs per week for the next three months, then 1000 IUs a day for another month and they’ll check it again. The USRDA is 400 IUs per day. Honestly, I hope this is the missing link in my health since I’m so tired and listless all the time.
