The deficiency of Vitamin D is very common and most people either do not have any symptoms or vague ones such as aches or tiredness. Extreme deficiency of Vitamin D may be the reason for soft bones called rickets in kids and osteomalacia in adults. Some symptoms are weak muscles, bone pain and bowing of leg bones in children. There can be muscle cramps and seizures very rarely in extreme deficiency of Vitamin D when calcium level is also very low.

The treatment is usually given by mouth once daily for 1 to 2 months. This will be followed by the lower dose taken every day to prevent the deficiency coming back.
