Effects of a curcumin-based supplementation in asymptomatic subjects with low bone density: a preliminary 24-week supplement study

摘要

OBJECTIVE: Osteopenia is a chronic bone condition characterized by decreased calcification, density, or bone mass that, if untreated, can lead to osteoporosis and bone fractures. Although its increasing prevalence, nowadays osteopenia is not adequately prevented and managed. In this study, we evaluated the efficacy, in term of changes in bone density, and safety of an oral formulation based on turmeric phytosome (Meriva?), in subjects suffering from low bone density. PATIENTS AND METHODS: 57 otherwise healthy subjects with low bone density were enrolled in this pilot, supplement study. Informed participants freely decided to follow either a standard management (SM) to control low bone density (control group=28) or SM associated with a curcumin-based oral supplementation (supplement group=29). The bone densities of heel, small finger and upper jaw were evaluated at inclusion and at different time points during the observational period (4, 12 and 24 weeks), in all subjects. RESULTS: The bone density of the heel measured by the Sahara densitometer remarkably improved in the Meriva?-supplemented group, with a significant decrease of ultrasounds transmission values at week 12 (-18.4%) and at week 24 (-21.0%), compared with baseline values. The bone densities of small finger and upper jaw also significantly increased during the study in supplemented subjects, reaching +7.1% and +4.8%, respectively, at week 24, with respect to values at inclusion. Noteworthy, no significant changes of heel, small finger and upper jaw densities were observed in the control group. Last, no safety and tolerability issues were reported during the observational period. CONCLUSIONS: This preliminary study suggests that a curcumin-based supplementation in combination with an appropriate lifestyle could be beneficial in the prevention and management of osteopenia.
