Multiple Sclerosis and (lots of) Vitamin D - book by patient on Coimbra protocol - Feb 2016 contains protocol description
Vitamin D Protocol used by Dr. Coimbra for Multiple Sclerosis etc.
Snips as of April 2016 http://www.vitamindprotocol.com/dr.-coimbra-s-ms-protocol.html

  • 1,000 IU's vitamin D per kilogram as a first approximation
    (apparently increased/decreased depending of resulting vitamin D blood level)
  • Vitamin B2, magnesium glycinate, boron, chromium picolinate, Omega 3 DHA, Zinc, Methylcobalamin form of B12, Choline, etc.
  • Lack of B12 may affect 10%–15% of the general population and may be the most prevalent genetic risk factor for several human diseases
  • Discontinue eating or drinking dairy products or calcium enriched foods or beverages, also no Ca supplements
  • Drink as least 2.5 liters [85 ounces] of fluids, preferably water
  • Required Tests:​ Vitamin D, Parathyroid, Blood calcium, urinary calcium

Genetic predisposition to multiple sclerosis (MS) only explains a fraction of the disease risk; lifestyle and environmental factors are key contributors to the risk of MS. Importantly, these nongenetic factors can influence pathogenetic pathways, and some of them can be modified. Besides established MS-associated risk factors –

  • high latitude,
  • female sex,
  • smoking,
  • low vitamin D levels
    caused by insufficient sun exposure and/or dietary intake, and
  • Epstein-Barr virus (EBV) infection
    - strong evidence now supports obesity during adolescence as a factor increasing MS risk.
  • Organic solvents and shift work have also been reported to confer increased risk of the disease,

whereas factors such as

  • use of nicotine or alcohol,
  • cytomegalovirus infection and a
  • high coffee consumption

are associated with a reduced risk.
Certain factors - smoking, EBV infection and obesity - interact with HLA risk genes, pointing at a pathogenetic pathway involving adaptive immunity. All of the described risk factors for MS can influence adaptive and/or innate immunity, which is thought to be the main pathway modulated by MS risk alleles. Unlike genetic risk factors, many environmental and lifestyle factors can be modified, with potential for prevention, particularly for people at the greatest risk, such as relatives of individuals with MS. Here, we review recent data on environmental and lifestyle factors, with a focus on gene-environment interactions.
