Vitamin D and the Brain
by: Kerri Knox, RN-The Immune Health Queen!

Hi Nick,

Ughhh. I'm not even sure where to START to answer your question!! There is so much evidence regarding vitamin D and the nervous system!!

The first thing that comes to mind is the relationship between Multiple Sclerosis and Vitamin D with quite a bit of evidence that MS is not only CAUSED by vitamin D deficiency, but MS can be put into remission by high dose Vitamin D as well.

Several researchers mention Vitamin D being a 'neurosteroid' and others talk about the 'Vitamin D Neuroendocrine System'. This Study talks about trying to create 'novel' new drugs to treat neurologic disease by targeting the vitamin D neuroendocrine system.

More About Vitamin D

Another study, shows the relationship between Association between 25-hydroxyvitamin D levels and cognitive performance on tests- a relationship that I'm sure that you are very interested in!

There have also been studies on Vitamin D and epilepsy- with some places using vitamin d as a primary TREATMENT of epilepsy - too bad most doctors and hospitals in the US is not so advanced!

There are also correlations with Vitamin D Deficiency and both Alzheimer's and Parkinson's.

You can see some of the research that I've collected on my Vitamin D Research Page as well as an ever growing library of research about vitamin D there.

Hope that this helped.

RN Knox, Your Opinions are at Variance
by: Anonymous

I'm not trying to be unkind, honestly but your disagreements with what symptoms can be caused by vitamin D deficiency are at total variance with huge numbers of other medical sources including medical research groups as a whole and board certified MDs, endocrinologists, osteopaths, etc...

The symptoms you claim have not been proven to be caused by vitamin D deficiency, including neurological ones, have huge numbers of references on medical sources saying it can and does cause them. The National Institute of Neurological Disorders and Stroke in fact states the link of MS and Vitamin D. Admittedly they don't state it to be the direct cause, however the association, whether a contributing factor or direct cause, has been well-substantiated.

The Mayo Clinic states this: "Vitamin D is known to promote both bone and muscle strength. Conversely, deficiency is an under-recognized source of diffuse pain and impaired neuromuscular functioning. By recognizing the association between Vitamin D and Pain, physicians can significantly improve their patients? pain, function and quality of life."

If I remember correctly ([Note from Kerri: Ummm, no you are not remembering correctly from MY site!} , you state in other articles that there is no link between Vitamin D and Fatigue.

Here again, it may sound like I'm being testy but it amazes me how we can bypass something obvious and not see the common sense answer. I admit again that most sources don't specifically mention fatigue and yet these same ones state that D deficiency causes muscle weakness, bone pain, autoimmune diseases, Heart Failure and Vitamin D, asthma, etc... but hasn't been 'proven' to cause fatigue.

How in the world can it do all of these things and yet fatigue not be a part of the complex?? The Vitamin Council call syndrome caused by D deficiency as "Vitamin D Deficiency Syndromes" and chronic fatigue and Symptoms of Fibromyalgia (NOTE: see my page on Fibromyalgia and Vitamin D is listed among the possibilities. The needing more medical studies to confirm an obvious gets a bit ridiculous in my opinion.

Sorry for the bluntness but I wouldn't hold my breath on seeing specific studies on these type things, therefore we have to keep telling people their fatigue is not related, nor are their neuro-symptoms.

Have you even read my site?
by: Kerri Knox, RN- The Immune Queen!

Hmmm. Very curious what site you were reading before you got to mine to say that my opinions are 'at odds' with the Symptoms of Vitamin D Deficiency that you reported.

I suggest that you actually Read my site before you say that I'm not up on the current Vitamin D Research.

I was the person who made the comment in regard to your info being at variance with other med sources.

I do indeed believe I was reading another site and attributing the pages to you. I'm not sure how I got my wires crossed and I'm usually very careful not to mix sources like that.

Your Vitamin D Research and links that you've provided proved to me that I was incorrect about your having made those statements. You in fact have covered all of the issues I originally made my comments about and much more.

My bad - and I sincerely apologize. Your site has far more compiled info on D deficiency and medical research sources than any I have yet searched-on.

Again, I am sorry for the mistaken identity and it certainly will not happen again, in fact your site is providing me a great source for learning more in regard to Vitamin D and other health subjects. I will also be checking out your Product Store for my supplement needs.

I'm glad you defended re: my comments and set me straight - appreciated!

by: Kerri Knox, RN- The Immune Queen!

Thanks for the apology. I work EXTREMELY hard to give people the most accurate and up-to-date information about the subjects that I report on. I'm always happy to have any inaccurate information pointed out to me, though. So, feel free to let me know in the future if you find anything inaccurate in my research.

Vitamin D and Neurological Problems
by: Rob

Over the past 7 months, I have suffered from full body random twitching and weakness. Another major symptom is that I have intensely vivid dreams (all night) where I wake up exhausted and find sleep unrefreshing.

The only thing my GP found was slightly low iron, slightly low Testosterone, and very low D (I think 19).

No one seems to think that my D deficiency is causing my symptoms. I was glad to find your site which seems to suggest the opposite, especially with the Neuro problems.

Could you forward me to any helpful articles?

I have also read that D causes vivid dreams, but I had/have them with a deficiency?! Thanks for any info on that.

Twitching and Insomnia are not 'Neurological Problems'
by: Kerri Knox, RN- The Immune Queen!

I'm not sure why you think that you have 'neurological problems'. Neither twitching nor insomnia are neurologic in nature. It sounds more like you simply have 'twitching'. The vivid dreams are possibly simply due to insomnia or due to restless leg syndrome, which is essentially making you sleep very lightly, which is why you are feeling unrefreshed. If you were sleeping deeper, then you probably wouldn't have such vivid dreams- plus vivid dreams in and of themselves are not a problem, nor are they a symptom of a problem necessarily, nor are they a cause of the problems that you are having.

The weakness MAY be a result of the vitamin d deficiency, however, could simply be a result of insomnia and/or restless leg syndrome. Months and years of not sleeping will make you very very tired, which will keep going to weakness, especially since you are unlikely to be getting any exercise.

Your vitamin d deficiency is probably 'incidental' and may even be a RESULT of your problems since it's unlikely that if you are constantly tired from insomnia, that you are not getting outside and getting any vitamin d. Since EVERYONE has a low vitamin d level, and after looking for everything else the doctors find low vitamin d levels, everyone wants to believe that low vitamin d is the cause of their problems. In your case, I doubt it.

Your problems sound like your typical and garden variety Signs of Magnesium Deficiency. Please see that page to see why that is likely to be your problem.

suffering from vit D and B12 deficiencies
by: A. Kumar


I have been diagnosed with vit D and vit B12 deficiencies 5 months vit D level was 11 and my B 12 level was 83. B 12 was diagnosed by a psychiatrist and I was askd to take B 12 injections(each was having a strength of 2500) for a month along with oral supplements( strength 1500). I had been having difficulty in concentrating, reading or working at the computer and watching TV. The words and pictures seemed to flash by and my eyes would become heavy. I was feeling constantly fatigued.I have been having dizziness for the past four years, along with a constant off balance feeling, depression and panick attacks for the last two years.No amount of visits to the doctors was helping me till I finally met this psychiatrist who acted as my saviour. However, the vit D deficiency was diagnosed by myself by extensive reading on the internet and your sites.

I have been prescribed with vit D injection 6 lac units last month and vit B12 methylcobal injections along with oral supplements and instantly I felt a lot better.My dizziness reduced and I was more alert. But again now after a month I am feeling the same, having the same brain fog and disorientation. I went to the doctor and have been asked to take another vit D and B12 injection and continue with the oral supplementations for another month before I go for a review again.

So how long do I need these injections to feel better and how long will my symptoms take to go. i am very tired of the doctor visits and though after 4 long years I finally seem to have found some relief I am scared of these relapses. I want to be completely fit as I was earlier.Any suggestions would be welcome.


Dear A kumar

Dear A kumar, I am in the same boat as you, both B12 and D deficient (B12:59, D:17). I have the exact same symptoms and has affected my work and study greatly. I just can't focus on words and retain.

I have been prescribed a course of 1 B12(methylcobal) injection(1000 MCG) every day for 5 days followed by 1 per week for 6 weeks followed by 1 every month for 6 months. This somewhat seems to be a standard pattern prescribed by doctors.

In addition I was prescribed 1 vit D3 injection followed by once a week oral tablets for 3 months.

So I am not sure why in your case it was only 1 or 2 injections. You may want to go to another doctor for a second opinion.

I too feel improvements in my thinking and focus however it still not perfect and I get the focus problems again at least once a week.

I am hoping that these effects go away after a few weeks and I can feel normal again. I totally understand the feeling as all this has caused depression for me and I am prescribed antidepressants for avoiding panic attack.

I will admit that reading your case has given me some hope that my doctor's diagnosis is correct and I may get better with time.

Note: As per my doctor the injections are a much sure and right way to treat severe deficiency as compared to oral tablets. Specially in cases like me with acidity and gastric problems (low absorbtion of oral tablet due to injured stomach)

Wish you a speedy recovery.

Vitamin D causes vivid dreams
by: Anonymous

Vitamin D definitely causes vivid dreams. I know that from personal experience with it. Every time I take it at night I have vivid dreams. When I stop taking it at night, the dreams stop.

My experience
by: Anonymous

This page has helped me a lot but I'm still trying to understand my symptoms, these past month I started feeling week, pain and tingly feeling on my arms, legs even on the tip of my fingers, I've been going pee a lot more, feeling dehydrated, feeling a sensation of non balance when stading,shaky and blurry vision, vertigo feeling, I felt like sometimes I had problems speeking and even thinking, I felt my brain wans't reacting fast enough like I was a zombie.

But well anyway, my doctor told me I could have diabetes or maybe anemia, so they did a blood test and it came out that I have vitamin D defiency... they are putting me on an antibiotic for 3 months, taking 1 pill each week, last week of the 3 months I have to go to the lab and have another blood test to see if I can just take an over the counter vitamin d supplement instead of the antibiotic and that's all they said to me, that's all I know.

Please share if you had these type of symptoms too, it will help me a lot and other people too. Thank you.
