The articles in both of the categories MS and Meta-Analysis are:

Note: >20,000 MS patients on Dr. Coimbra Protocol are being treated by 150 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

  • Sunlight exposure as a source of Vitamin D has been hypothesized as a protective factor for multiple sclerosis(MS) due to immunomodulatory effects of vitamin D.
  • Our study found
    • each 25 nmol/L increase in serum 25(OH)D levels is associated an average 10% decrease in new relapses and a
    • 14–31% reduction in the risk of new radiological inflammatory activity inpatients with early relapsing MS.
  • Relationship between serum 25(OH)D levels and disability worsening remains inconclusive and deserves further investigation as disability is the main relevant outcome for MS patients.
  • The effects of serum 25(OH)D levels in progressive MS and non-White populations also warrants further investigation.

Vitamin D supplementation is recommended for patients with multiple sclerosis (MS). However, a recent meta-analysis based on low-quality trials suggested no evidence of supplementation benefit. A systematic review and meta-analysis of high-quality observational cohort studies should provide us further evidences.

MEDLINE, EMBASE, and WEB-of-SCIENCE databases were systematically searched to identify eligible studies published before October 2018. Prospective cohort studies assessing the associations of serum 25(OH)D levels with MS relapses, radiological inflammatory lesions, or changes in expanded disability status scale in adults (≥18 years) with MS were included. Pooled RRs were calculated using fixed-effect or random-effects model depending on heterogeneity.

Thirteen studies and 3498 patients were included. Each 25 nmol/L increase in serum 25(OH)D levels was associated with a reduction in

  • (1) clinical relapse rate [RR = 0.90; 95% confidence interval (CI) = 0.83–0.99],
  • (2) gadolinium-enhancing lesions (RR = 0.69; 95% CI = 0.60–0.79),
  • (3) new/enlarging T2 lesions (RR = 0.86; 95% CI = 0.77–0.95), and
  • (4) new active lesions (RR = 0.81; 95% CI = 0.74–0.89) in the magnetic resonance imaging(MRI).

Serum 25(OH)D levels are associated with a modest decrease in relapse rate and radiological inflammatory activities in patients with MS. The association with disability worsening remains inconclusive.
