β-Carotene prevents bone loss in hind limb unloading mice

β-Carotene has been reported to be useful to maintain a positive balance of bone turnover. However, the effects of β-carotene on bone loss remain to be elucidated in mice with hind limb unloading. Therefore, we investigated whether β-carotene prevented bone loss induced by skeletal hind limb unloading in mice. Female 8-week-old ddY mice were divided into six groups (n = 6-8 each) and subjected to: (1) normal housing, (2) sham unloading fed a...
