Our bodies usually produce large amounts of vitamin D3 (cholecalciferol), the most bioactive form, when our skin is exposed to sunlight. Obviously in winter, especially in very northerly or southerly latitudes, our exposure to sunlight is very low as we wrap up in thick clothing and hide away indoors where it's warm. As a result our vitamin D production can drop to almost zero and deficiencies become a problem. Vitamin D deficiency has been implicated in a number of serious illnesses, from osteoporosis to cancer and high blood pressure. Vitamin D deficiency can also have a marked effect on mood, with studies showing that people with low vitamin D levels are far more likely to suffer from depression than those with higher levels.

The fat soluble vitamin D is confusingly named, as it is actually a powerful hormone. It has a major role in the conversion of the amino acids to neurotransmitters , tryptophan to serotonin, and tyrosine to dopamine and norepinephrine. It performs this role within the brain, and in the adrenal glands. Much of this is performed through vitamin D's close relationship with calcium, as calcium literally controls the communication between neurons (brain cells). This relationship with calcium is also why vitamin D is important for bone health. The neurotransmitters , dopamine, and norepinephrine have a huge impact on mood, , the result is depression. Since sun exposure and vitamin D production are much lower in the winter, most vitamin D deficiency related depression is in the form of SAD.

Your convinced. "I think therefore I am". The hypothalmus is the problem not vitamin deficiency.

Edit:
Try taking vitamin-D and get your blood level up between 50-80 ng/ml. It will regulate your testosterone, serotonin and melatonin level to normal.

The hypothalamus does the regulating not vitamin D.

Why do I get the distinct feeling that we'll never know?


Great minds think alike.

The biological clock don't work properly if there’s not enough vit-D to connect the receptors.

The clock does not work properly because of a malformed hypothalamus, vitamin d levels are regulated by the hypothalamus as well.

I'm out of this circle jerk.

Yes, it's so simple that we didn't pay it any attention.

Some Med’s and PhD’s who don't get paid by the medical industry believe that in a period of 10 years half of the industry worldwide have to shut down due to the result of the vitamin-D research.

Thanks Potter. You have only contributed with some stupid comments in this thread. IMHO very childish. 

Hi Mark,

The reason why I started this tread was to tell your all what I have experienced by taking Vitamin-D. I have tried to figure out what’s the cause of CH the last 10 years and have finally found something that works for me. I started researching  Vitamin-D and have found that it’s very important for all our cells and hormones in our body to work properly.

No, there’s another one on this forum:

Yes I believe that, because the talented researcher’s haven’t paid vitamin-D any attention in their research of CH, yet.

I think that one of the issues is that when your suffer from a rare disease like CH, your also expect that the cause is something rare and special. But still I’m convinced that the main cause is low level of Vitamin-D. Just wait and see.

Best
Niels

Having been through the stock market's .com boom and bust of the late 90's, there was a distinguishing aspect to news labeled PR, which was corporate promotional and to be noticeably wary of its foundation.

PR releases were tools used by companies as mouthpieces, launching opportunities to build a market, create visibility, support activity, drive traffic as direct to consumer vehicles.


The article seems sourced from a compiling site, yes, and yet as you indicate, under a tab that says press release, but at the very top of the site, this is their little message:


Promote Everything About Your Business on PR.com


Promote, as in "self promote". 

In this creating of "word of mouth", today there is sometimes the retweeting "mommy blogger", which may "coincidentally" happen somewhere in a thread, too.

Things may not have really changed much in ten years.

What about this one?

Fifteen years ago, there were some promising case studies. Since then, no one has bothered to look at whether vitamin D can help.  Instead, the money goes to developing yet another triptan which can be sold for $40 a pop.

Hypothalamus, schmipothalamus ... sure, it is involved. But there are a ton of chemicals that people take that can prevent or abort ... does oxygen fix the hypothalamus? Triptans? Lithium? Kudzu? Olanzapine? Histamine desensitization? Verapamil? Cluster busters?  Melatonin? Magnesium?  Taurine?

Who is to say that vitamin D won't someday be added to the list?

Just a remark. Sumatriptan does NOT regulate serotonin level in any way. It just acts like serotonine acts against some receivers. It's a so called "selective agonist" of serotonin.

Regards.

In general, low brain serotonin levels are associated with increased sensitivity to pain, and chronic pain sufferers appear to have reduced serotonin functioning. Serotonin is known to have an effect on pain awareness, in part by controlling the release of a pain-signalling brain chemical called substance P. Sumatriptan acts the same way.
