Summary: In a retrospective study involving 221 chronic fatigue syndrome (CFS) patients, results indicate a significantly high prevalence of low vitamin D status. Serum 25-OH vitamin D levels were measured in the patients and found to be moderately to severely suboptimal in CFS patients, with a mean of 44.4 nmol/L (optimal levels >75 nmol/L). The mean serum vitamin D levels were observed to be significantly lower than a control group of patients attending a hospital for other chronic conditions, and to a large British longitudinal survey of 45-year old women. Thus, the authors of this study conclude, "This data supports the recommendation made in recent NICE guidelines that all patients with moderate to severe CFS should be encouraged to obtain adequate sun exposure and eat foods high in vitamin D. Oral or intramuscular vitamin D supplementation should be considered for those whose levels remain suboptimal."
