    Chronic Fatigue Syndrome

    Chronic fatigue are also as myalgic encephalomyelitis (ME), post-viral fatigue syndrome (PVFS), and various other names, is a syndrome of unknown and possibly multiple etiologies, affecting the central nervous system (CNS), immune and many other systems and organs. There is no simple diagnostic test. CFS is a diagnosis of exclusion, although recent research indicates biological hallmarks of the syndrome and a diagnostic test is predicted soon. CFS occurs more often but not exclusively, in women, possibly due to immunological factors as women are overall more susceptible to similar disorders. CFS is most easily diagnosed when formerly active adults become ill but it has been reported in persons of all ages which include young children and particularly teenagers.

    Role of Vitamin D

    Vitamin D regulates immune functions of monocytes and neutrophils. Neutrophils are white blood cells that ingest invasive bacteria and act as the first line of protection once bacteria make it past the skin barrier. Despite its name, vitamin D is not a true vitamin but it could best be described as a conditional vitamin, since human skin can create it in some circumstances. Vitamin D is also known as calciferol.

    Causes of Chronic Fatigue Syndrome (CFS)

    Some cases of CFS start gradually but the majority starts suddenly, often triggered by a flu-like viral or similar illness. People with CFS may improve or recover after several months or many years or not at all. It is not known whether any CFS sufferer has truly recovered to pre-illness levels or whether their symptoms have merely subsided enough for them to live a more normal life. Some sufferers have a remission for months or years only to later relapse and often more severely too.

    Low Vitamin D can Cause

    Fatigue, Depression and Seasonal Affective Disorder can be the cause of low vitamin D. Activated vitamin D in the adrenal gland regulates tyrosine hydroxylase, the rate limiting enzyme necessary for the production of dopamine, epinephrine and norepinephrine. Low vitamin D may contribute to chronic fatigue and depression. Seasonal Affective Disorder has been treated successfully with vitamin D. In a recent study the treatment comparing Vitamin D and depression is completely resolved. The requirement for vitamin D has been pegged to these disorders ever since.

    1. Edward Hutchinson says:

      Each 400iu of vitamin D3/daily can raise vitamin d status by 9nmol/l.

      Absorption of calcium from diet is maximised at a vitamin d status of 80nmol/l. This level has recently also been shown to reduce colon cancer incidence by 72%.
      In order to ensure all your body’s systems have access to vitamin d when needed 100nmol/l are required.

      125nmol/l this is regarded as optimal vitamin d status and is linked to lowest overall cancer incidence, you also achieve peak muscle performance at this level.
      Sunlight is the best, cheapest source of Vitamin D3 as only 10% can reasonably be obtained from food sources.

      Depending on how old you are, where you live and how much time you spend outdoors your vitamin d status in winter probably drops down to 40nmol/l if aged 45 and 23nmol/l if elderly.
      It follows that 2000iu-4000iu/daily/vitamin D3 may be needed in winter to achieve optimal status. Risk assessment for vitamin d. details the research showing 10,000iu/daily is totally safe as 40,000iu/daily is needed daily for some months to raise status to 350nmol/l before hypercalcemia or other adverse events occur.

      In summer regular SHORT, full body sun sessions can provide the 4000iu/daily your body uses. However, it may be sensible to use effective strength (1000-2000iu/daily) in summer if your weather or other factors stop you exposing more than hands/face regularly.
