Vitamin D Deficiency Symptoms
Question: What are the symptoms of vitamin D deficiency?
Answer: Long-term, severe vitamin D deficiency can cause bone softening and weakening in children (known as rickets) and adults (osteomalacia). Symptoms associated with vitamin D deficiency can include chronic headache, bone pain, muscle weakness, insomnia, depression and hair loss. However, because these symptoms can be vague and/or easily attributed to other causes, the best way to know if you are deficient in vitamin D is to have your blood levels tested.
