I am going to start this thread, because the subject seems very
new and important.

Everyone is welcome to post on this thread any additional data, personal experiences and questions.

Here is one link I just found concerning diabetic neuropathy:

This study was small, and unblinded, but is interesting nonetheless IMO.

On this link Mark describes how his improvement occurred after he starting fixing is low Vit D status:

Search Mark._. to read his previous posts with his symptoms.

This is the link to D-Action...the group that made the medical video that is on YouTube currently:

and here is their video which I link to often:

This link also has alot of information on Vit D:

I've been watching the boards carefully for a long time here.
All of the boards are showing low D levels in patients who get tested. I think I have only seen a couple who were in the 40-50 ng/ range! Many have tested very low, almost in the single digits!

It is best to get a blood test to see where you really are. However, the recommendation now, is that 2000IU a day are safe for people who do not have testing. This dose may not raise you much, but there is nothing to say, it is dangerous.

The only exception to this remains those patients with sarcoidiosis. This inflammatory disease appears worse in patients who have higher D levels. This is not understood yet, and until that time that more data are available, those with sarcoid should consult their doctors before using Vit D supplements. Sarcoid is not a common disease.
This link discusses prevalence of Sarcoid and gives data for various ethnic groups and ages most commonly affected:

If one looks at the links above, one can see some of the new data coming out about Vit D status and chronic pain.

One myth still surrounds Vit D... and that it can be had from the diet. This is just not true. 8oz of milk typically have 100IU of D2 added!
If you live in colder climates, or do not go out into the sun without sunscreens, you cannot make your own Vit D adequately.
