Vitamin D - Ideal Results and Poor Results
In the Recovering with T3 book, in Chapter 4, I discuss vitamins, minerals and the possible connections to hypothyroidism. However, I failed to say anything about specific results and reference ranges for vitamin D specifically.
I thought I would mention more here as I am not planning to do a revision of the book to correct this omission.
There are many pieces of research that show links between low vitamin D and hypothyroidism and autoimmune disorders. I discuss this in the Recovering with T3 book in Chapter 4 so I won't go over that again here. However, it is worth noting some of the symptoms of low vitamin D.
These include: depression, bone loss, bone pain, hair loss, fatigue/tiredness, muscle pain, frequent infections, vascular diseases, abnormal heartbeats, seasonal affected disorder (and even some more serious diseases have links to low vitamin D).
The Vitamin D Council have guidelines on the ranges for vitamin D when measured in blood in both ng/ml and nmol/L. To go from ng/ml to nmol/L just multiply the ng/ml number by 2.5.
The ideal range: 40-50 ng/ml (100-125 nmol/L).
Not quite sufficient: 30-40 ng/ml (75-100 nmol/L).
Insufficient: 20-30 ngl/ml (50-75 nmol/L).
Deficient: 10-20 ngl/ml (25-50 nmol/L).
Severely deficient: 0-10 ngl/ml (0-25 nmol/L).
Many readers will already be aware of all the above but I wanted to add this short blog post to complement the information in the blue book (Recovering with T3).
It is also worth noting that if vitamin D3 is used to address any deficiency of vitamin D then magnesium is a necessary co-factor for absorption of D3.
