Hi guys.

I have a level of <20 nmol. I DO NOT have any disabling muscle or bone pain. My main symptoms are dizziness, nausea and weakness. Loss of co-ordination (tripping, loss of spatial awareness), irritability, inability to think straight, at worst times I find it uncomfortable to even talk as my brain feels so dense. I normally have to stare at the floor to keep my footing. Sometimes people think I'm drunk in public.

Surely all that can't just be vitamin D? What's going on here?

All my other blood results are in healthy ranges.

(Please do not launch into telling me how much vit D I should be taking, cofactors and so on. I have read up on that stuff. My question is about my symptoms)

Thanks x

    They could be due to the low vit D but vit D is often a symptom of autoimmune disease and they are also symptoms that would make ME think of an autoimmune disorder - but that is only because I know so many people with a/i disorders.

    I would ask my doctor for a referral to a neurologist or a rheumatologist for a start. Let an expert make a decision, this sounds out of a GP remit. You could wait until your vit D is in normal range - and I hope your GP hasn't just told you to "go and buy some"!

      Thank you for your answer.

      40'000 IU a day for a week then 800 IU plus calcium a day for the next two months. If no change then I'll ask for more investigation.

      40,000IU per day is an awful lot - 10,000IU/day for a few weeks is probably safer and easier on your body. My husband took 25,000 IU a week for 4 months - no problems at all and level brought up nicely. Our GP said that it is thought a moderately high dose works better than very high doses. 800 IU is neither here nor there - not even enough to cover the daily need so won't contribute much to raising a low level.

    Have you had your serum B12 and serum Folate levels tested as some symptoms of deficiency in either of these are similar to those you describe.

    I'm not medically trained but have had Pernicious Anaemia (a form of b12 deficiency) for 45 years and I too am on a Vitamin D supplement

    I wish you well
