Lack of sunshine linked to Parkinson's
A lack of the vitamin obtained by exposure to the sun has been linked to Parkinson's disease, research has found.

A study of elderly people with Parkinson's or Alzheimer's disease found they were more likely to have insufficient levels of vitamin D than healthy people of the same age.

More than half of patients with Parkinson's had low levels of vitamin D, along with 41 per cent of those with Alzheimer's disease.

Only 36 per cent of health elderly people had low vitamin D.

It is not clear if a lack of the vitamin contributes to the development or progression of the neurological disease or whether it could be a symptom.

In addition more Parkinson's patients were clinically deficient in vitamin D, 23 per cent compared to 16 per cent of Alzheimer's patients and 10 per cent of patients with neither disorder.

Parkinson's patients are now being given supplementary vitamin D in either standard doses or large doses to investigate the effect on the progression of the disease.

The study was carried out by Emory University School of Medicine in Atlanta, Georgia and is published in the Archives of Neurology.

The body makes vitamin D from exposure to sunlight, small amounts are present in certain foods such as fish and cereals and milk can be fortified with it.

Study author Marian Evatt said: "We found that vitamin D insufficiency may have a unique association with Parkinson's which is intriguing and warrants further investigation."

The most common symptoms of Parkinson's are tremour, stiffness and slowness of movement as nerve cells in the brain become affected by the disease.

Dr Evatt said the part of the brain affected by Parkinson's has a high number of vitamin D receptors which may suggest a mechanism for the connection.

In the UK there are around 120,000 people with Parkinson's and around 10,000 are diagnosed each year.

I'd ask for a Vit D test at the doctor's. Many people are coming on the various health boards with neuro and pain issues, and testing very low.

I myself take 2000IU daily for a maintenance dose. (I do not take it in summer when I am outside alot).

There are two kinds of Vit D. D3 is the preferred one.
Milk only has 100 IU in 8oz. and it is D2.
New studies have shown no side effects with doses as high as
10,000 IU of D3 daily.

Historically D2 was the only one available for decades, but new D3 is actually very available now OTC and not expensive.
NOW brand makes a nice liquigel..and I'd recommend that over dry tablets to improve absorption.

This new article recommends 400 IU for infants now!

Thank you for this post. I have been thinking a lot about Vitamin D (the sunshine vitamin) because over the last two years it has become increasingly
obvious to me that I have a better time on sunny days, or even days when I just get outside and it's warm enough to stand around in a short sleeved shirt.
I rarely drink milk anymore, and the best source is a little sun. I'm sure thats why I would die for a holiday in Hawaii or Mexico in February. Would we get enough in a good multi-vitamin? How much is enough?

standard vitamin mixtures reflect the old Vit D paranoia, and
have quite low doses. (200-400IU)

You really have to read the link I gave above.

Within the last 5 years the Vit D research has exploded, and
Vit D deficiency has become a huge priority.

You would really have to take Vit D as a stand alone
supplement. D3 is very INexpensive.

This is the one I use:

How inexpensive is THAT? And with high quality too.

I'd really recommend getting a blood test first. If you don't, I would not go above 2000 IU until you really know where you are. Estimates now are that 1/2 of all Americans are deficient.

I just heard a report obout this on our local news this evening. Sound promising. mrds, you say you are taking 2000ui. Does it seem to have any effect for you? One thing that comes to mind with being in the sunshine is the sunshine naturally causes an endorfin release. As most know, endorfins go to the pleasure center of the brain. Amazingly, the same place our dopamine goes.

That had 1000 IU.But it had alot of A.

I get out in the sun alot in the summers, at our summer home
in the boonies, on the shore. I come home highly tanned, and feeling great. Then the great decline begins in earnest starting in October. Two winters ago I bought a light visor, and at least I don't have the depressive reactions now.

But last year I upped to 2000 IU in the winter. And combined with the light visor, I am SO MUCH better, mood wise!
I have some PN and arthritic chronic pain issues, so while I am not PD (yet) I am still in that neuro danger zone.
There are new studies even showing increasing Vit D along with light therapy helps too. But I didn't know that then.

Given the low price of quality D3, it is really not even a hardship in any way to provide it.

But what is frustrating is that doctors are testing now for it, and I guess they went to some CME courses that taught it.
But they are treating with the old antiquated D2 which is Rx and is 50,000 units ...and that seems like a huge dose, but in reality it is not, because D2 is not active, and not as useful as D3. But there is no RX version of D3, so they just don't get that part, yet. That RX D2 has been around as long as I have been alive-- older than dirt. Times have changed, but the therapeutic manuals are not up to date. This is also true for B12 therapy and magnesium (magnesium oxide is old as dirt too and not effective we know now).
