ABSTRACT
BACKGROUND:
Supplementation of individual micronutrient is inadequate for maintaining bone function because single micronutrient can not contribute significantly a positive remodeling balance.OBJECTIVE:
We developed the highly integrated, stably dietary multi-micronutrients with good bioavailability and low adverse effect on the improvement of bone consolidation in osteoporosis.METHODS:
The trace element-codoped calcium phosphate (teCaP) particles were prepared in the modified body fluid and carefully evaluated. Rats, aged 3 months, were ovariectomized and when 6 month intervened with the conditioned, low, moderate, and high teCaP diets.RESULTS:
The teCaP particles showed highly dissolvable in stomach juice-mimicing acidic solutions. Three months after intervention, the body weight increase showed remarkable differences among the low teCaP diet (~52 g), moderate teCaP diet (~34 g) and high teCaP diet (~23 g) group. In particular, the intake of moderate teCaP greatly improved the retention of trace elements in femural bone for better protection against the skeletal weakening, and resulted in a significant increase of bone mineral density (104.06%) in comparison with the conventional high calcium plus vitamin D3 diet (Control group).CONCLUSIONS:
These investigations improve our understanding of micronutrient retention on bone consolidation in osteoporotic bone tissue, and also provide new mild wet-chemical approach to prepare potent nutritionally effective edible complements to synergistically relieve bone degeneration and prevent osteoporosis.
