I've heard that melatonin may increase the risk of broken bones. I take melatonin regularly. Should I be concerned?

Answer:

Regular, long-term use of melatonin has been associated with an increase in fractures, which is also the case with some prescription sleep medications. While it's true that melatonin may slightly increase bone density, it may do so by inhibiting the normal cycle of bone resorption and formation, which can make bone less flexible, more likely to fracture, and slow healing after a fracture occurs.
