I bought some iron, magnesium, calcium, zinc, primrose oil, b12 and this thyroid vitamin which contains bladder wrack, l tyrosine, kelp and they all have directions on how much to take but not sure if it's the correct amount. Also I looked for ferritin and could not find any. Is there a link with recommended dosage. And yes, I'm hypo and I am off Armour. I was taking 60 mg 2 grains for last two years. I have been off Armour for about eight weeks now. And yes the shedding had eased up and not like it was.
