Which vitamins??

How do you guys know which vitamins to supplement with?

Should I add Selenium and Magnesium?

If I have it correct I need to add vitamin D and I think B, some of which are bad.

Just diagnosed with under active and I think hashimotos as well.

Also considering gluten free but that scares me stupid at the moment and only just starting to get my head around levo and vitamins..

Purple80 As you have Hashimoto's you should supplement with selenium as it is supposed to help with reducing the antibody attacks.

In the thread you posted with your blood test results, Clutter advised on your vitamin and mineral levels and suggested what to take.

With the D3 that you need to supplement, you should also take K2-MK7 and magnesium, both of these are Vit D co-factors. Vit D aids absorption of calcium from food and K2 directs the calcium to bones and teeth rather than soft tissues and arteries. Both D3 and K2 are fat soluble and should be taken with dietary fat. Magnesium is calming and is best taken in the evening.

B12 should be a sublingual one as that is dissolved under the tongue and gets straight into the bloodstream. If B12 is swallowed or chewed then it will be destroyed by stomach acid. Look at Solgar or Jarrows sublingual methylcobalamin. When taking B12 we also need a B Complex to balance the B vits. Thorne and Jarrows are good makes, but whichever brand you get look for methylfolate (natural) rather than folic acid (synthetic) in the ingredients. B vits should be taken in the morning as they can be stimulating, preferably no later than lunchtime.

I'm not Hashi's so have no experience of gluten free but many members who do have Hashi's say that adopting a gluten free diet has helped enormously and that it's not necessarily expensive as you don't have to buy expensive ready made gluten free foods but just prepare everything yourself from scratch but also read labels carefully on any packaged food you do by.


Thank you, yes I understood what I was told I meant brands more than anything...


vitamin D

B12 - under tongue

B complex - natural

K2 - Mk7

What does with dietary fats mean?

Magnesium in the evening.

How do you know all of this?

Is there an idiots guide to the thyroid I can read?

Dietry fats means things like butter, and olive oil, or animal fat. So, for example, if you have a nice fatty pork chop for diiner, it would be good to take your vit D3 just after that.

We learn through reading, reading, and reading some more. On here for example. There are lots of books about thyroid, but l don't know of one that gathers all this information in one place. So, as you read, make your own notes. Perhaps, one day, who knows, you might publish your osn idiots guide to thyroid. :)


Purple80 "Is there an idiots guide to the thyroid I can read?" - Not an idiot's guide but a really good book, written in a way that's understandable, is 'Your Thyroid and How to Keep It Healthy' by the lovely Dr Peatfield - you can see it on Amazon amazon.co.uk/Your-Thyroid-H... . I found it quite an easy and pleasant read and very informative, and nice to dip into when you need a snippet of information you may have forgotten.

"How do you know all of this?" - I read, research and find it eventually sinks in, plus I have been hypo for over 40 years with mainly idiot doctors which makes you want to find out all you can to help yourself.

Brands I like or use:

Vit D - I like Doctor's Best D3 because it is a small softgel which contains only 2 ingredients ie D3 and extra virgin olive oil, no unnecessary fillers/rubbish we don't need.

B12 - I use Solgar sublingual methylcobalamin lozenges and am very happy with them, a lot of members use those, some choose Jarrows.

B Complex - I used Thorne Basic B. Some people use Jarrows B Right although a couple of members haven't got on with that one.

K2-MK7 - the one I use is in a combo so I won't suggest mine, but just Google it and see what you can find, if it says 'from Natto' that is fine as that is fermented soy, the only form of soy us Hypos should take.

Dietary fat is a meal containing fat of some description, the fattiest meal of the day, or even something like toast with proper butter, a full fat yogurt. D3 and K2 are fat soluble vitamins so must be taken with some fat.

Other advice I would give is to stay away from cheap supplements such as supermarket brands, H & B own brand, etc. They are cheap because they tend to use the cheapest ingredients which are usually the wrong form. I tend to look for words like Bioavailable, Wholefood, Food State, Fully Active.

There are quite a few types of magnesium which all are suitable for different things - have a look here and see what would suit you best naturalnews.com/046401_magn...


Thank you, thank you, thank you 😄



Can I ask you how much K2 you take?



MiniMum97 The usual dose is 100mcg.


I suppose one of the issues is the brain fog. I'm finding it hard to take it all in and remember things.

I will start writing things down...

Thank you 😄

My brain fog has lifted since supplementing B12, B Complex and D3. Good luck!

I am new too. Yes there are lots of vitamins. I bought most of mine from Amazon.

I was initially scared of going gluten free but I'm getting used to it. It's easy to find if it's in things as allergens are all bolded on the ingredients section of food items. I flicked through my cookbooks and was relieved to see most of my favourite recipes don't have any gluten or soy in them :-) Phew!

I am using this time now to get my head around having to take a huge life overhaul. I remind myself that "tomorrow has finally arrived!" No more putting off regular exercise or eating healthier. Now I have NO choice or excuse to delay !!

We are fortunate to have found this forum early on :-)


Yes your right about that, I have just downloaded he book SeasideSusie mentioned.

What's wrong with soy?


"However, if you are still consuming any form of unfermented soy, you want to stop that right away! It will nullify any thyroid hormone replacement that you do decide to take because it stops the hormones getting into the cells"

Above is what greygoose advised me in response to one of my posts.

Yikes, adding that to the list of things to avoid! Thanks


Unfermented soy is anti-thyroid in two ways : firstly, it impedes the up-take of iodine by the thyroid gland. Iodine is one of the 'ingredients' of thyroid hormone. Not enough iodine means not enough thyroid hormone, which makes you hypo.

Secondly, it impedes the up-take of thyroid hormone replacement by the cells, and therefore keeps you hypo.


Does this apply to those of us who have had our thyroid removed due to cancer?


Actually, you should put off regular exercise until you're optimal. Everything you do uses up your hormones, including T3. And, if you're just taking levo (T4) you will have a hard time replacing it. So, if you find that you are taking a couple of days recovering from your exercise, then it's too much for you, and you should stop it. Just gentle walking, swimming or yoga until you have sufficient levels of T3. And, even then, listen to your body, and don't over-do things.


Just a thought a bit off topic. You could support Thyroid Uk through easy giving. No cost to you but you get a small donation sent to the charity of your choice. Amazon is one of many outlets that do this.
