Melatonin may stop bone loss

In a study recently published in the Journal of Pineal Research, researchers examined the effect of 3 mg of supplemental melatonin on eighty-one postmenopausal women with osteopenia (pre-osteoporosis). At the end of one year, not only did bone-loss cease, bone density actually increased. The exact mechanism of action of melatonin on bone density is not known. Further research will be needed to see whether this increase in bone density can help prevent fractures.
