The main barrier to therapeutic development is a lack of efficacy for improving clinically relevant outcomes, such as physical function or QOL, yet most nutraceutical studies focus on body weight. This review describes clinical and pre-clinical nutraceutical studies outside the context of complex nutritional and\/or multimodal interventions, in the setting of cancer cachexia, in view of considerations for future clinical trial design. Clinical studies mostly utilized polyunsaturated fatty acids or amino acids\/derivatives, and they primarily focused on body weight and, secondarily, on muscle mass and\/or QOL. The few studies that measured physical function almost exclusively utilized handgrip strength with, predominantly, no time and\/or group effect. Preclinical studies focused mainly on amino acids\/derivatives and polyphenols, assessing body weight, muscle mass, and occasionally physical function. While this review does not provide sufficient evidence of the efficacy of nutraceuticals for cancer cachexia, more preclinical and adequately powered clinical studies are needed, and they should focus on clinically meaningful outcomes, including physical function and QOL.<\/jats:p>","DOI":"10.3390\/cancers15153884","type":"journal-article","created":{"date-parts":[[2023,7,31]],"date-time":"2023-07-31T01:48:50Z","timestamp":1690768130000},"page":"3884","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["A Review of Nutraceuticals in Cancer Cachexia"],"prefix":"10.3390","volume":"15","author":[{"given":"Lucas","family":"Caeiro","sequence":"first","affiliation":[{"name":"Geriatric Research, Education and Clinical Center, Veterans Affairs Puget Sound Health Care System, Seattle, WA 98108, USA"},{"name":"Division of Gerontology and Geriatric Medicine, Department of Medicine, University of Washington School of Medicine, Seattle, WA 98195, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Devika","family":"Gandhay","sequence":"additional","affiliation":[{"name":"Geriatric Research, Education and Clinical Center, Veterans Affairs Puget Sound Health Care System, Seattle, WA 98108, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3810-2427","authenticated-orcid":false,"given":"Lindsey J.","family":"Anderson","sequence":"additional","affiliation":[{"name":"Geriatric Research, Education and Clinical Center, Veterans Affairs Puget Sound Health Care System, Seattle, WA 98108, USA"},{"name":"Division of Gerontology and Geriatric Medicine, Department of Medicine, University of Washington School of Medicine, Seattle, WA 98195, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jose M.","family":"Garcia","sequence":"additional","affiliation":[{"name":"Geriatric Research, Education and Clinical Center, Veterans Affairs Puget Sound Health Care System, Seattle, WA 98108, USA"},{"name":"Division of Gerontology and Geriatric Medicine, Department of Medicine, University of Washington School of Medicine, Seattle, WA 98195, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,7,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"489","DOI":"10.1016\/S1470-2045(10)70218-7","article-title":"Definition and classification of cancer cachexia: An international consensus","volume":"12","author":"Fearon","year":"2011","journal-title":"Lancet Oncol."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"348","DOI":"10.1017\/S0029665115000117","article-title":"Cachexia: Clinical features when inflammation drives malnutrition","volume":"74","author":"Laviano","year":"2015","journal-title":"Proc.
