    Abstract:
    Preventing the decrease in bone mineral density (BMD) is significant for postmenopausal women. We previously discovered that rhamnose, a deoxy monosaccharide used as a food additive, could suppress bone resorption; however, studies confirming this effect in postmenopausal women are lacking. Therefore, this pilot study aimed to explore whether rhamnose could help maintain BMD via bone resorption suppression in postmenopausal women. The participants consumed either 1.0 or 0.5 g/day of rhamnose or placebo for 24 weeks, and BMD (lumbar spine and femur) and bone turnover markers were measured. After 24 weeks, the group consuming rhamnose 1.0 g/day exhibited a significantly higher BMD of the lumbar spine than the placebo group. Furthermore, the levels of tartrate-resistant acid phosphatase 5b, a bone resorption marker, were significantly lower in both rhamnose groups. These results indicated that rhamnose might contribute to the maintenance of BMD by suppressing bone resorption in healthy postmenopausal women (UMIN000046570).
