You mentioned ferritin and b-12 in another post having to do with thyroid. The practitioner I was seeing, who diagnosed me as hypothyroid, said my b-12 and ferritin levels were normal. What do these normal levels say about my thyroid condition?
My TSH is High and the T4 they tested was low. So I'm def. Hypothyroid just wanted to see if the normal values of the other 2 things meant anything in particular. The thyroid issue I believe I have had for a while but it is just recently that I am learning about it.
"Normal" is relative. Ferritin is optimal when in the 70-90 range for women and above 100 in men. B12 is optimal when it is in the upper 800's. If your ferritin and b12 aren't in the above ranges, but simply "in range" then your b12 and ferritin isn't optimal and you should supplement.
I just wanted to add, that if we are talking about thyroid, it is being discussed that possibly the best way to test for hypothyroidism is by looking at the ratio of free t3 or total t3 to reverse t3. Just google it, there is a lot of new research stating that this should be the marker for hypothyroidism.
