Vitamin D is important in helping the immune system function properly. A recent study at the Mayo Clinic shows that lymphoma patients with vitamin D deficiency are twice as likely to die from this cancer as patients with adequate vitamin D levels. Those who were deficient had less than 25 nanograms/milliliter of total vitamin D in their bloodstreams. The specific malignancy that was studied was a type of non-Hodgkin’s lymphoma that affects the B cells.
