[Ari3]

Hi there,

I wanted to ask you people when we test vitamin D through NHS it says Serum total 25-OH Vit D level -is this active vitamin d3 or d2 they are testing ?

Thank you

Not open to a simple yes or no answer.

The Sandwell and West Birmingham lab, which as City Assays offers vitamin D testing to the public, gives both figures.

I suspect that it will be the sum of D2 and D3 in most labs that don't give them separately.

Yes I think it's the sum - see mayomedicallaboratories.com...

So it shows combined d2 and d3 vitamin levels ? Is this correct ? I have checked through west Birmingham labs(private test) vitamin d3 upon my nutritionist request so it’s more accurate and it’s d3 also separate as d2 . It showed 86nmol/L which is sufficient is this level ok for someone who has Hashimotos ?

Is it City Assays who did the test, and it says SWBH - Sandwell and West Birmingham Hospitals NHS Trust? If so then they measure both Vitamin D3 and D2 giving a ‘Total Vitamin D’ level and it will say that on their result sheet which you should have received, it looks like this

The Vit D Council, the Vit D Society and Grassroots Health all recommend a level of 100-150nmol/L so your level of 86nmol/L isn't quite there and you would be advised to nudge it up into the recommended range.

Yes that is the one I did and it said adequate and my result was 86 of vitamin d3 . So it means even it shows adequate I should improve it and get it to 100-150 nmol/L?

The result saying it's adequate is like a GP saying because your TSH is 4.1 with a range of 0.2-4.2 then your thyroid is fine. So 86nmol/L is adequate but it's not optimal. Whether you want to follow the recommendation of the Vit D Council, the Vit D Society and Grassroots Health is up to you. I need my Vit D result to be at the top of the recommended range, even if it's 106 I get bone pain in my leg.

I hope my nutritionist will sort me out she was waiting for these results and started me on lower dose as 2000iu vitamin d3 with k2 but I think I will be at least on 5000iu soon to get it up .does normal person need to have vitamin d on top of range or just Hashimotos ?

[SeasideSusie Remembering in reply to Ari3]

Well, I don't have Hashi's and I'm better with my level at around 150nmol/L.

[Ari3 in reply to SeasideSusie]

Probably that is why I have back pain and muscle aches all over

[userotc in reply to Ari3]

Ideally 100-150 is best (search other posts on but d on this forum). Yes I believe d is sum of D2 and D3.

[Ari3 in reply to userotc]

So there is a room for improvement ?

[userotc in reply to Ari3]

Ideally yes

[userotc in reply to userotc]

Note my level is increased from deficient to 100-110 in a few months by supplementing 5000iu/day - a dosage I've continued with to maintain that level. Note I don't have hashis.

[Ari3 in reply to userotc]

Oh gosh so will need higher doses than thank you
