To estimate the associations between vitamin D status and multiple sclerosis (MS). We searched electronic databases of the human literature in PubMed, EMBASE and the Cochrane Library up to February, 2014 using the following keywords: 'vitamin D' or '25(OH)D' and 'status' or 'deficiency' or 'insufficiency' and 'multiple sclerosis'. A systematic review and meta-analysis were conducted on observational studies that reported the association between blood vitamin D levels and MS. Eleven studies met the inclusion criteria. 1007 patients and 829 controls were included.
Results of our meta-analysis show that MS patients had lower mean levels of 25-hydroxyvitamin D [25(OH)D] than healthy controls (weighted mean difference[MD], -14.52, 95% confidence interval CI, -23.83 to -5.22). There were statistically significant heterogeneity (P<0.00001; I(2)=92%). The significant heterogeneity may be due to the differences in ethnicity, country, season of blood sampling and age of the participants studied. To sum up, low vitamin D levels are associated with an increased risk of MS.

Overview MS and vitamin D contains the following summary
Clinical interventions have shown that Vitamin D can prevent, treat, and even cure Multiple Sclerosis, at a tiny fraction of the cost of the drugs now used to treat it, and without side effects.

Summary: lack of consensus on how much to prevent, treat, or cure MS.

  • How much Vitamin D to prevent many diseases - such as MS
  • How much Vitamin D is needed to treat MS? There is currently no agreement
       The recommendations range from 40 to 100 ng - which can result of a dose ranging from 3,000 to 20,000 IU/day
  • How Vitamin D is needed to Cure MS?: It appears that 20,000-140,000 IU daily may be needed to CURE the disease
       You must be under the supervision of a doctor who knows what to watch for in your individual situation.
       High doses of Vitamin D cannot be used as a monotherapy.
       You will need to adjust the cofactors: Typically increasing Magnesium and Vitamin K2, and reducing Calcium intake.
       Your doctor will monitor these and might increase your intake of Vitamins B2, C, as well as Omega-3
