Yes, low vitamin D can cause fatigue.
More Info: Did you know that a deficiency in vitamin D causes chronic fatigue? About one billion individuals all over the world have low vitamin D levels. It is now recognized as a pandemic, with children and young adults being the highest groups at risk for having such deficiency.
Definition of Chronic Fatigue

Definition of Vitamin D Deficiency
According to the Vitamin D Council, a non profit organization which aims to educate the public about the benefits of Vitamin D, vitamin D deficiency is found in individuals who are afflicted with two or more of these conditions: osteoporosis, heart disease, hypertension and chronic fatigue, among others. Further, it is measured as having levels of less than twenty ng per milliliter of 25-hydroxyvitamin D.
Chronic Fatigue and Other Vitamin D Deficiency Symptoms
One of the effects of having low vitamin D levels is having chronic fatigue. Vitamin D deficiency also results in rickets. Because having low vitamin D levels means that calcium is not absorbed by the body properly, it can also lead to osteopenia, osteoporosis and fractures. Vitamin D deficiency also places you at risk for cancer, autoimmune diseases and infectious diseases.
One of the main reasons why vitamin D deficiency is a global pandemic is because it is hard to find natural food that is rich in this vitamin.
Another cause of vitamin D deficiency is lack of sun exposure. Because the sunlight is an essential source of vitamin D, people who live in colder climates and are extensively covered up all year, are deprived of vitamin D.
