Vitamin D and human health
The main reason for me (Gavin Giovannoni, neurologist) recommending vD supplements is for other potential health reasons, in particular bone health. I see little reason to justify leaving MSers in a vD deficient  state (while waiting for more evidence). This is why I recommend vD supplementation with the aim of keeping levels above 100nmol/L or 40ng/ml all year round.

Vitamin D for All to Prevent MS?
George Ebers, MD, University of Oxford, United Kingdom (UK), at ECTRIMS said, "When looking at the risks, costs and benefit equation, the risks of universal supplementation with vitamin D to reduce the risk for multiple sclerosis (MS) seem tiny, and the benefits are yet to be established but indirect studies are supportive. The cost of vitamin D is dirt cheap but the costs of MS are staggering and are increasing."

Commentary, if I had CIS with MRI diagnostic of MS, I would take vitamin D 10,000 IU daily
If the debate question was framed as “Would I prescribe vitamin D 10,000 units to a patient with clinically isolated syndrome and an abnormal MRI scan?”, then the answer is, of course, “No”. I agree with the antagonists in this debate that phase 3 trial data are needed before using vitamin D as a therapeutic agent. However, those trial data will take at least another 2-3 years to collect. Thus, while waiting for that proof, if I, or my children, developed a clinically isolated syndrome with an abnormal MRI scan, then I would have no hesitation in prescribing vitamin D in that dose for them.

Relationship between 25OHD serum level and relapse rate in multiple sclerosis patients before and after vitamin D supplementation

The vitamin D3 supplementation increasing vitamin D serum levels, up to 110 nmol/L (44 ng/ml), with a plateau effect beyond this level. Suggesting, therefore, that it is particularly useful to correct vitamin D deficiency in MS patients when present. Vitamin D deficiency (< 100 nmol/L) is present in 90% of the MS patients. Furthermore, because of the plateau effect beyond 110-120 nmol/L, it may not be necessary to prescribe high, not physiological vitamin D doses (beyond 4000 IU/day).

Vitamin D in MS A vitamin for 4 seasons
The results of 3 independent studies published in Neurology® suggest that higher levels of circulating 25-hydroxyvitaminD (25OHD) may reduce relapses and lesions on MRI in persons with multiple sclerosis (MS). It is too soon to recommend the use of high-dose vitamin D in clinical practice. Meanwhile, considering the high prevalence of vitamin D insufficiency and deficiency in persons with MS, the high risk of osteoporosis, and the safety of vitamin D at modest doses, the evidence is sufficient to recommend monitoring of vitamin D levels and supplementation as needed to achieve at least a year-round level of vitamin D sufficiency in persons with MS.

However, the possibility of reverse causality cannot be ruled out completely. Randomized intervention studies are therefore needed to investigate the effect of vitamin D supplementation in MS.

These findings suggest persons being treated with IFN-β should have vitamin D status monitored and maintained in the sufficiency range.
