10 Vitamin D3 Deficiency Symptoms
Symptom #2: Fatigue and Tiredness
Fatigue is such a weird feeling. You get 8 hours of sleep, yet you still feel tired. Fatigue can really have a negative impact on quality of life. One potential cause of fatigue is a deficiency of vitamin D.
Numerous studies have been done on the association between vitamin D and fatigue. One study involved a woman who complained of chronic daytime fatigue, who was found to have a vitamin D level of only 5.9 ng/ml. Keep in mind, the normal range of vitamin D ranges from 20–50 ng/ml. Thus, she was significantly deficient in the vitamin. The participant was supplemented with vitamin D, until her blood levels reached 39 ng/ml. Her fatigue drastically cleared. Her experience is mirrored in another study done on nurses and fatigue. It was found, of the nurses who experienced fatigue, 89% were also deficient in vitamin D.
