Hi all, can anyone clarify. I know biotin affects blood results for thyroid tests. Can I take Vit b supplements containing biotin during taking levothyroxine?
Do i need to take biotin?
What B vitamins are most important to take?
Can anyone recommend a good brand with no fillers or crap in them?
Thanks
Forum advice is to stop supplements with biotin 5-7 days prior to blood draw.
I like to take B vitamins in a morning, at least 2 hours away from levothyroxine

Personally, I’ve had good results with both Thorne Basic B and Ingennus Super B. Advantage of the latter is the tablets are smaller.
It is very difficult to answer part of that. All vitamins are essential. What you need to take are the ones you are not getting in sufficient amounts from your diet.
At the same time, it can be important not take too much of some of them. Like B6. And to take appropriate forms, vitamers, of them.

Some time ago, I mentioned that the form in which we take vitamin B6 is important. I think I linked to this paper below.

What are your most recent B12, folate, ferritin and vitamin D results
Test these at least annually
And always test BEFORE starting on any supplements
I've not had any yet. I've been taking vit D for a while. Didn't think too much Vit D could be any issue?
Vitamin D is not water soluble so yes too much can be an issue
Test vitamin D twice a year when supplementing
And if you don’t know your levels how would you know if you are taking high enough dose
How much vitamin D are you taking
GP will often only prescribe to bring vitamin D levels to 50nmol.
Some areas will prescribe to bring levels to 75nmol or even 80nmol
leedsformulary.nhs.uk/docs/...
GP should advise on self supplementing if over 50nmol, but under 75nmol (but they rarely do)
mm.wirral.nhs.uk/document_u...
But improving to around 80nmol or 100nmol by self supplementing may be better

Once you Improve level, very likely you will need on going maintenance dose to keep it there.
Test twice yearly when supplementing
Can test via NHS private testing service
Vitamin D mouth spray by Better You is very effective as it avoids poor gut function.
There’s a version made that also contains vitamin K2 Mk7.
One spray = 1000iu

It’s trial and error what dose we need, with thyroid issues we frequently need higher dose than average

Web links about taking important cofactors - magnesium and Vit K2-MK7

Vitamin K2 mk7
Strongly recommend you get folate, ferritin and B12 and vitamin D tested now
BEFORE starting any B vitamins
Thanks for advise. I'll get these tested will stop vit D and test in a couple of weeks so I know what's what. Thanks
You don’t need to stop vitamin D until day before test
The iimportant thing with B vits is that they all work together and need to be kept balanced. Which is why we recommend taking a B complex.
As to the 'no fillers or crap in them', a pill has to have fillers to hold it together. Otherwise it's a powder.
