Potential of Kefir-Derived Peptides, Probiotics, and Exopolysaccharides for Osteoporosis Management

Abstract

Purpose of ReviewOsteoporosis is a prevalent skeletal disorder in postmenopausal women and older adults. Kefir has gained attention for its potent antioxidative, anti-inflammatory, and immunomodulatory properties. This review consolidates findings on kefir-derived peptides' interventions in osteoporosis models and evaluates the therapeutic potential of kefir components in preventing osteoporosis, thereby enhancing its application in clinical nutrition strategies for osteoporosis management.Recent FindingsKefir-derived peptides exhibit osteoprotective potential in various animal models of osteoporosis, in which several antioxidative and ACE-inhibitory peptides have been shown to promote osteoblast differentiation and mineralization. In addition, emerging evidence supports the role of kefir-derived probiotics and exopolysaccharides (kefiran) in mitigating bone loss.SummaryKefir holds significant promise in the management of osteoporosis due to its unique composition of bioactive components promoting bone health. While research is still in its early stages, evidence suggests kefir's potential as a natural approach to osteoporosis prevention and management.
