I used to have the ‘brain fog’ for years, even after I start taking the thyroid
medication. I started with 75 mcg levothyroxine, then only 60 mg
Armour now I take 75 mcg Synthroid AND 60 mg Armour. Only after I start taking both medications I stopped having the ‘brain fog’.
Regarding the vitamins, now I take lots of vit C, all the Bs, especially B12 and the rest in low quantities.
As far as the weight, well this is another story.
