Research progress on nutritional properties of Antarctic krill oil and its improvement on osteoporosis
Antarctic krill oil(AKO)is a novel marine functional lipid.In order to promote the clinical application of AKO,the nutritional composition of AKO was summarized,the mechanism of AKO in improving osteoporosis was described,and the future key work was prospected.AKO is rich in phospholipids,n-3 polyunsaturated fatty acids(n-3 PUFA),astaxanthin,α-tocopherol,and other bioactive factors.There are three mechanisms for AKO to improve osteoporosis,namely,inhibiting osteoclastogenesis,promoting osteoblastogenesis,and regulating bone marrow mesenchymal stem cells.Future in-depth investigations into AKO should focus on large-scale clinical trials,standardized dosages,and long-term efficacy validation.
