Expert discussions with Prof. Dr. Jörg Spitz

Bisphosphonates and Vitamin D in the fight against cancer – a breakthrough for treatment?
Vitamin D acts more like a hormone than a vitamin, and most cells in the body have receptors for it. Some people may not respond well to vitamin D at the cellular level even when their blood number looks fine. The conversation argues that parathyroid hormone is a more useful marker of adequacy than blood vitamin D alone.
