I don't know for certain but I imagine that they should all be 'optimal' the same as for Hypothyroidism ie
Vit D: 100-150nmol/L (or 40-60ng/ml)
B12: top of range
Folate: at least half way through range
Ferritin: at least 70, preferably half way through it's range
This article on ThyroidUK's main website talks about the role of vitamins and minerals 'in thyroid disease' and when you read through the different ones you will see some talk specifically about Hyperthyroidism
thyroiduk.org.uk/tuk/treatm...
At the bottom there is a list of recommendations by Dr Arem who says that if you are overactive, you should take them even if your levels are high.
B12 - I would advise against trying to use serum B12 as a way of ensuring your B12 levels are 'optimal' - it isn't a direct measure of what is happening with B12 in your cells. There isn't a definitive test for this so you need to go by symptoms - though that is complicated because of the overlap with the symptoms of thyroid conditions.
In general, unless you have an absorption problem, your body is very good at regulating your B12 levels using reserves in your liver. If you have an absorption problem then you will see serum B12 levels falling over time - but bear in mind that there can be a bit of variation just from testing the same sample so you would be looking a trend of significant drops over time.
If you have an auto-immune thyroid condition then there is a high possibility that you will develop auto-immune gastritis which will result in problems with a number of vitamins and minerals - iron is often the first to develop as a problem - but B12 can be particularly effected and if it is then the drop in ability to absorb B12 from your diet is quite dramatic.
Please also note that ferritin is just one measure of iron status and although it tends to be a good guide it doesn't give the whole picture so again, using serum ferritin can be problematic. There has been at least one case of someone suffering from iron poisoning because ferritin was acted on as a single measure.
