New trial shows treating vitamin D deficiency significantly improves fatigue symptoms

Posted on: September 24, 2014   by  Amber Tovey


A new study published in North American Journal of Medical Sciences found that vitamin D deficiency was common among patients with fatigue, but also found that bringing vitamin D status to a sufficient level significantly reduced symptoms of fatigue.

Fatigue can impact almost every aspect of your life, including your social life and work performance. However, most diagnoses of fatigue are idiopathic, meaning they have unknown causes.

It has been suggested that vitamin D deficiency and fatigue are closely related. Some researchers think that fatigue is a symptom of vitamin D deficiency, while others think there are other factors involved.

For example, osteomalacia is a disease that can be caused by vitamin D deficiency. Muscle weakness is a common symptom of osteomalacia and can lead to fatigue.

    I was constantly fatigued until I started taking vitamin D. I couldn’t figure out how I could eat well, get 8 hours of sleep a night, and jog every day while still experiencing a constant, low-grade, run-down feeling. Cholecalciferol to the rescue! They probably used D2 because D3 at that dose is not widely commercially available. Biotech should get in there!

    No doubt we as a family are a lot healthier since taken D3 supplement .

    First, I must comment on how impressed I am with your research and continuing release of results. Secondly, noticing that the recommendation above suggests 5,000IU daily. What do you now commend for an ER+ cancer patient (no chemo; no mastec), 71 yrs, who has extreme fatigue. My labs were 21 about 2 mos ago; I started @ 2,000IU and have moved to 4,000IU daily. My fatigue is lessening which I can’t help but attribute to D. Your response would be appreciated. Mahalo from Hawaii!
