Neuropathy and Vitamin D

Do any of you know of any connection between Vitamin D deficiency and neuropathy?

Mark here has already posted benefits since he started Vit D
supplements.

but I couldn't open the link.

I started to take vitamin D 2 days ago.

It is a PDF...if you don't have Adobe reader?

try it again, maybe a glitch?

The article is about Vit D healing damaged axons.

I can't open the link either, and I do have Adobe Reader, even the new updated Reader 9. It says our computers do not accept cookies, but that isn't true either...I think it may be a bad link.

I would like to read about neuropathy and Vitamin D though. Thanks

I have Mozilla as a browser and it opens it.
I got this link from another forum, and we cannot link to there.

I don't know how to copy PDFs either.
here is a quote from it that was posted at the other place:

To date, the use of autograft tissue remains the “gold standard” technique for repairing transected peripheral nerves. However, the recovery is suboptimal, and neuroactive molecules are required. In the current study, we focused our attention on vitamin D, an FDA-approved molecule whose neuroprotective and neurotrophic actions are increasingly recognized. We assessed the therapeutic potential of ergocalciferol—the plant-derived form of vitamin D, named vitamin D2—in a rat model of peripheral nerve injury and repair. The left peroneal nerve was cut out on a length of 10 mm and immediately autografted in an inverted position. After surgery, animals were treated with ergocalciferol (100 IU/kg/day) and compared to untreated animals. Functional recovery of hindlimb was measured weekly, during 10 weeks post-surgery, using a walking track apparatus and a numerical camcorder. At the end of this period, motor and sensitive responses of the regenerated axons were calculated and histological analysis was performed. We observed that vitamin D2 significantly (i) increased axogenesis and axon diameter; (ii) improved the responses of sensory neurons to metabolites such as KCl and lactic acid; and (iii) induced a fast-to-slow fiber type transition of the Tibialis anterior muscle. In addition, functional recovery was not impaired by vitamin D supplementation. Altogether, these data indicate that vitamin D potentiates axon regeneration. Pharmacological studies with various concentrations of the two forms of vitamin D (ergocalciferol vs. cholecalciferol) are now required before recommending this molecule as a potential supplemental therapeutic approach following nerve injury.

I don't understand why I can open the link and others cannot.

Doses are not discussed for humans. It remains a good idea to get tested to see where you stand. If you self medicate you may take too little to see benefit.
But many people that post on boards with chronic pain issues are seeing low levels come back from testing, and improvement with D3 supplements. (D2 is less effective)

I can't open it either
It takes me to

& It gives me this message (direct cut & paste)

I don't get it. And I don't have any hits on my 3 scans I do weekly either.

Here is the paper on PubMed...looks like what I quoted above.

Most of the paper is all about pipettes and lab protocols etc, and how the study was run actually. The only other part was the mention of only using D2 (because that is what doctors are familiar with).

I went to the site and removed part of the url---

This also works for me and has the "cookie" bit removed.

That last link was the charm! Thanks! - j

that last one works for me now also.
