Swedish case-control study compared 670 people who got MS vs 670 who did not get MS
Vitamin D levels were taken about 8 years before the MS
15.5% of those WITH MS previously had >30 ng of vitamin D
20.5% of those WITHOUT MS previously had >30 ng of Vitamin D

UV and Sunshine reduces MS risk

Other things also help

High Dose Vitamin D and cofactors

Number of MS studies which are also in other categories

  • 22 studies in Genetics - genes can restrict Vitamin D getting to the blood and to the cells
  • 12 studies in Vitamin D Receptor - gene which restricts D from getting to the cells
  • 7 studies in Vitamin D Binding Protein - gene which restricts D from getting to the cells
  • 21 studies in Ultraviolet light - may be even better than Vitamin D in preventing and treating MS
  • 9 studies in Omega-3 - which helps Vitamin D prevent and treat MS

High 25-hydroxyvitamin D concentrations have been associated with a reduced risk of multiple sclerosis, with indications of a stronger effect among young individuals.

Investigate the 25-hydroxyvitamin D association with multiple sclerosis and test if this association is age dependent.

Prospectively drawn blood samples from individuals later developing relapsing–remitting multiple sclerosis and controls matched for biobank, sex, age and date of sampling, were analysed with liquid chromatography tandem mass spectrometry.

High levels of 25-hydroxyvitamin D (top quintile) were associated with a reduced multiple sclerosis risk (odds ratio 0.68, 95% confidence interval 0.50–0.93).

These findings further support a role for vitamin D in MS aetiology.
