Are there of long term symptoms of vitamin d deficiency?

Yes: Long term vitamin d deficiency in adults can lead to osteomalacia (bone softening) and osteoporosis (bone density loss, causing easy fracturing). Other symptoms of a deficiency of vitamin d are muscle pains, muscle weakness, and aches in the bones. In children, prolonged vitamin d deficiency causes rickets (bony deformities).

We keep finding more: Vitamin d doesn't just effect bones. It acts as a hormone within the body, and over 300 genes have been identified that are either activated or inactivated by vitamin d. Deficiency has been associated with a variety of pain syndromes and autoimmune conditions, increased risk for a variety of cancers, and increased susceptibility to a variety of infections. We learn more daily.

>200 genes affected: Vit d seems to influence more than 200 genes in body and daily requirement is upwards of 2000 iu daily - to reset acidic pH we use 12000 international units twice daily for 3 weeks followed by 6000 units twice daily for another 3 weeks - so in acute disease process the requirements are very high.
