Evidence supports the benefits of interventions such as physical exercise and dietary supplementation with vitamin D, calcium, and protein in this population. Additionally, emerging supplements\u2014such as creatine, \u03b2-hydroxy-\u03b2-methylbutyrate (HMB), probiotics, and prebiotics\u2014are being investigated for their potential to enhance bone density, muscle mass, and physical function. This review aims to examine the current evidence on these novel nutritional strategies and provide a comprehensive synthesis of how these factors may synergistically influence both muscle and bone health. Methods: A comprehensive literature search was conducted across the PubMed\/MEDLINE, Embase, Scopus, and Google Scholar databases. Relevant observational studies, clinical trials, systematic reviews, and meta-analyses published from January 2020 to June 2025 were included, and then a reverse search in the bibliography was used to expand on definitions and concepts. Conclusions: Nutritional interventions for osteosarcopenia play a pivotal role in not only improving bone and muscle composition but also enhancing functional outcomes in older adults. Emerging strategies involving creatine monohydrate, HMB, probiotics, and prebiotics show potential as part of a comprehensive patient-centered approach. However, further research is needed to determine the most effective strategies and to identify which patients are most likely to benefit from each supplement.<\/jats:p>","DOI":"10.3390\/nu17142332","type":"journal-article","created":{"date-parts":[[2025,7,16]],"date-time":"2025-07-16T10:46:05Z","timestamp":1752662765000},"page":"2332","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Beyond Calcium and Vitamin D: Exploring Creatine, \u03b2-Hydroxy-\u03b2-methylbutyrate, Prebiotics and Probiotics in Osteosarcopenia"],"prefix":"10.3390","volume":"17","author":[{"given":"Jos\u00e9 Eduardo","family":"Moreira-Velasco","sequence":"first","affiliation":[{"name":"Geriatrics, Tecnologico de Monterrey, Monterrey 64700, Nuevo Le\u00f3n, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9582-1175","authenticated-orcid":false,"given":"Maria Fernanda","family":"Contreras-Alvarado","sequence":"additional","affiliation":[{"name":"Geriatrics, Tecnologico de Monterrey, Monterrey 64700, Nuevo Le\u00f3n, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hassan","family":"Rammal","sequence":"additional","affiliation":[{"name":"Bone, Muscle & Geroscience Group, Research Institute of the McGill University Health Centre, Montreal, QC H4A 3J1, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-6338-7843","authenticated-orcid":false,"given":"Daniel","family":"Rivas","sequence":"additional","affiliation":[{"name":"Bone, Muscle & Geroscience Group, Research Institute of the McGill University Health Centre, Montreal, QC H4A 3J1, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8126-0637","authenticated-orcid":false,"given":"Gustavo","family":"Duque","sequence":"additional","affiliation":[{"name":"Bone, Muscle & Geroscience Group, Research Institute of the McGill University Health Centre, Montreal, QC H4A 3J1, Canada"},{"name":"Dr. Joseph Kaufmann Chair in Geriatric Medicine, Department of Medicine, McGill University, Montreal, QC H3A 2B4, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,7,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"111997","DOI":"10.1016\/j.mad.2024.111997","article-title":"Deciphering Osteosarcopenia through the hallmarks of aging","volume":"222","author":"Franulic","year":"2024","journal-title":"Mech.
