Abstract

Background: Chronic Fatigue Syndrome (CFS), or Myalgic Encephalomyelitis (ME), is a debilitating disorder characterized by extreme fatigue that is not improved with rest and worsens with physical or mental exertion. Recent studies suggest a potential role of micronutrient deficiencies, particularly Vitamin D, in the pathophysiology and symptomatology of CFS.

Objective: To assess the prevalence of Vitamin D deficiency in adults diagnosed with Chronic Fatigue Syndrome. Methods: A cross-sectional study was conducted involving 100 adult patients (aged 18–60 years) diagnosed with CFS based on CDC criteria. Serum 25-hydroxyvitamin D levels were measured, and deficiency was defined as <20 ng/mL. Demographic data, fatigue severity, and comorbidities were recorded and analyzed.

Results: Among the 100 participants, 68% were found to have Vitamin D deficiency, 22% had insufficiency (20–30 ng/mL), and only 10% had sufficient levels (>30 ng/mL). A significant association was found between Vitamin D deficiency and higher fatigue severity scores (p<0.01).

Conclusion: Vitamin D deficiency is highly prevalent among adults with Chronic Fatigue Syndrome. Screening for and correcting this deficiency may be a valuable adjunct in managing fatigue symptoms.

I was just looking at this one, started off with an okish definition and then quickly goes into just referring to “CFS”.

They apparently used the Fukuda criteria which may explain some of this but by the conclusion it seems to reach almost comic levels of misunderstanding

The study concludes by pointing out that vitamin D insufficiency is quite prevalent in an urban adult population that is mostly young and that it is significantly correlated with hypothyroidism and the degree of weariness. In order to address this frequently disregarded factor that contributes to chronic tiredness and the burden of disease, these findings highlight the necessity of greater awareness, early identification, and maybe supplementary options

It seems like they forgot to consider that more fatigued people probably are outside less, and therefore might have lower vitD as a result.
 
Who determines what nutrient levels are optimal for a random human, and what are the tolerances? Obviously we're not at death's door if we're 5% low one day. ME forced me to live on mostly cornstarch for a year or so, and aside from occasional VitC tablets, my nutrient intake was probably negligible. From the supplement industry claims, I probably should have been dead, or at least seriously impaired, rather than shoveling snow or soil, or other such strenuous activities. So, I don't put much weight on RDAs.
