Bone Health


Based on cell and preclinical data, it has been suggested that melatonin acts on both anabolic and catabolic aspects of bone metabolism  (1). Over the years, limited published clinical trials using a relatively small number of study subjects have demonstrated melatonin’s role in rebalancing bone remodeling in perimenopausal women (2) and increasing bone density in postmenopausal women with osteopenia (3). In these studies, up to 3 mg of supplemental melatonin was used. According to findings from the year-long clinical trial referred to as Melatonin-micronutrients Osteopenia Treatment Study (MOTS), a combination of melatonin (5 mg), strontium (citrate) (450 mg), vitamin D3 (2000 IU/50 mcg) and vitamin K2 (MK7) (60 mcg) may be able to favorably impact bone markers such as bone mineral density in postmenopausal, osteopenic women, compared with placebo (1). In addition to beneficially modifying bone markers, the intervention improved quality of life measures such as mood and sleep quality (1). Of course, it cannot be inferred that melatonin was responsible for these effects since it was given as a combination supplement.


Investigators reviewed melatonin as a pivotal compound in age-related skeletal muscle disorders because of its involvement in mitochondrial function through its antioxidant potential (4). Any research findings in this direction may be helpful for those with cachexia or sarcopenia. Furthermore, these authors suggested that it would be interesting to explore melatonin’s effect on the gut microbiome as it relates to skeletal muscle (the ‘gut-muscle axis’) (4).
