This study will be assessing the efficacy of melatonin and/or osteogenic loading on modulating bone health in an osteopenic population.

Inclusion criteria: To be included in the study, the participant must be a male or female with osteopenia (T-score between -1.0 and -2.5) who is at least 18 years of age. The participant must be willing to undergo an osteogenic loading protocol once per week and/or take a pill (placebo or melatonin) for one year.

The study participants must also be willing to get a DXA scan at months 0 and 12 at one of the three Weinstein Imaging locations.

Exclusion criteria: Women or men with osteoporosis; women or men with osteopenia due to hyperparathyroidism, multiple myeloma, metastatic bone disease, chronic steroid use including corticosteroids; women or men who are on any bone therapies (i.e. bisphosphonates, selective estrogen receptor modulators (SERMs), hormone therapy, teriparatide, and denosumab); men and women with chronic obstructive pulmonary disease (COPD); women or men who smoke; pregnant women; and men or women with muscular dystrophy, unmedicated hypertension, or unrepaired hernia, restrictions to movement and exercise, and parathyroid dysfunctions.
