Reply To: Hi. I have had subclinical hypothyroidism for over 13 years and my GP has finally agreed to treat. As my VitD level was insufficient at 33 nmol/L (Range 50 – 150 nmol/L) in July 2013 and I have learnt that the two can be linked so I took a private test and discovered that my VitD is now deficient at 28nmol (>50nmol being described as adequate). The doctor has put me on VitD3 4,000 IU for 12 weeks but made not mention of K2-MK7 or magnesium which someone mentioned on the TyroidUK website. My questions are:
As I am overweight is 4,000 IU an appropriate dose?
Should I be supplementing with K2-H7 and Magnesium? IF so what is the recommended dose?
I would appreciate any help you can give.
