The effect of human-like collagen calcium complex on osteoporosis mice

The objective of this study was to assess the effect of a modified human-like collagen calcium complex on osteoporosis mice. BHK (Baby Hamster Kidney) cells were used to compare the cytotoxicity of different calcium reagents with the MTT test. Six-week-old male mice (n = 80) were randomly divided into eight groups: a blank group (blank), control group (control), human-like collagen calcium group (HLC-Ca), thiolated human-like collagen calcium group (SH-HLC-Ca), phosphorylated human-like collagen calcium group (Pi-HLC-Ca), gluconate group (Glc-Ca), calcium carbonate group (CaCO3) and D-cal group (B). A systematic analysis of the results available in vivo after 3 months of treatment was presented. The effects of several Ca supplements on osteoporosis mice were investigated by detecting serum calcium, alkaline phosphate activity (ALP), bone hydroxyproline (BHP) and bone mineral density (BMD). The results proved that the BMD and BHP of osteoporosis mice were significantly increased in the Pi-HLC-Ca group, while serum calcium and ALP were decreased. Therefore, Pi-HLC-Ca is likely a good calcium supplement for clinical applications. In this review, the advantage of Pi-HLC-Ca in preventing and delaying osteoporosis is highlighted. In addition to the current progress, further investigations are necessary to reveal the relative influences of collagen and calcium proportions on the long-term clinical effects of osteoporosis.
