supplements for hashimotos hypothyroid

Hi can anyone help me I'm getting really confused looking at all the different charts whilst trying to work out if I need to take any supplements in the hope of getting my ducks inline as the stem people say. I'd be grateful for comments on my bloods and any recommendations of types of supps, should I need any. I think I may need a little B12 and iron but may be totally wrong

many thanks

vit d 99.8 50-120 mol/L

b12 522 197-771ng/L

ferritin 83.8 13-150ug/L

serum iron 18.7 5.8-34.5umol/L

serum transferrin 2.76 2.02-3.56g/L

transferrin saturation index 27.1% 20-55%

still waiting on selenium but have started that as have tpo >600

ft3 4.2 3.1-6.8pmol/L

ft4 18.7 10.3-24.5pmol/L

tsh 1.26 0.4-5.5miu/L

VitD and ferritin are optimal.

B12 >500 is very unlikely to be deficient but as PA Society say 1,000 is optimal you may want to supplement 1,000mcg methylcobalamin with a B Complex vitamin.

If you feel well your thyroid levels are fine.  If you are symptomatic there is scope to increase dose to raise FT4 and FT3 which will lower TSH.  Read Treatment Options in thyroiduk.org.uk/tuk/about_...

Thank you for helping. I suffer with brain fog quite frequently which make work in particular hard. I'm going to try the b12 and go from there, hopefully that will. 


Hello, I've been hypo Hashi for 2 years now, Levo does nothing to help my brain fog, I'm now on a combination of the following supplements. A good multivitamin, high dose zinc+Silenium 10000uG of b12 and 700mg of magnesium these have helped LOADS(stopped leaving the hob on and walking away from cash points leaving my money behind!!) xxxx


Thanks. I know exactly what u mean. I'm sure I'd forget my head if it wasn't attached. Do u buy ur supps online?


So Holland and Barrett it's expensive, but not as expensive as not treating the brain fog and walking away from a cashpoint and leaving 60 quid behind!! Lol
