bardie53, To properly comment, members need to know the accompanying ranges for these numbers, so do add these if you can.

Also, what is your lab's comment about your results? Most testing labs give an assessment of your results.

No accompanying range that's why I've put on here. These are results from my GP that I asked for, have other 4esults but they had ranges, this one doesn't.

Testing labs have different ranges. So I can't accurately compare yours to mine for example.

Even without ranges, there should be some indication given by the ab. It might say, for example, 'deficient' or 'adequate' or 'high', and maybe even suggest whether supplementation is recommended.

Nothing, what I've posted is as it is on my records.

These are the categories set by the NHS lab that does Vit D testing for the general public and you can see that your level comes into the insufficient category. The Vit D Society and Grassroots Health recommend a level of 100-150nmol/L, with a recent blog post on Grassroots Health mentioning a study which recommends over 125nmol/L so if you wish to improve your level you may wish to supplement with D3 and it's important cofactors - magnesium and Vit K2-MK7.

Here are the ranges from MMH, which is an NHS lab.46 would come into the Adequate category.

Crikey, even the NHS can't agree 🙄

I think it's the same as many other tests. Depends on the equipment in the particular lab doing the test.

I think that saying anything over 100nmol/L is excessive is very conservative. I keep my levels as close to 100 as I can because that is where I feel best, but I wouldn't be worried if my level went a bit higher.

With vitamin D below 50nmol

GP should prescribe 1600iu everyday for 6 months

NHS Guidelines on dose vitamin D required

ouh.nhs.uk/osteoporosis/use...

GP will often only prescribe to bring vitamin D levels to 50nmol. Some CCG 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

pubmed.ncbi.nlm.nih.gov/218...

Once you Improve level, very likely you will need on going maintenance dose to keep it there.

Test twice yearly via NHS private testing service when supplementing

vitamindtest.org.uk

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

If I self supplement, how long would I stay on a supplement before I have a break from it?

Most people need to supplement during winter and Spring. If you are outdoors with bare skin exposed to sunshine in the summer, you can take a break from supplements.

Would I get a general Vit D supplement or a D3 supplement?

RedAppleAdministrator in reply to bardie53

Most UK brands are D3, which is the accepted form these days. Lots of people find this one does the job really well, but there are plenty of other brands in pill form. smile.amazon.co.uk/BetterYo...

It varies from person to person

I have Hashimoto’s and gluten intolerant…..found after approx 6 years regularly testing twice year …I need 4000iu daily in summer and 5000-6000iu daily in winter …that maintains my vitamin D levels at 80-100nmol. (Was deficient at 12nmol when first diagnosed as hypothyroid)

Others might need considerably less ….a few might need higher dose
