In the present study, the potency of policosanol (POL) was assessed for its ability to prevent metabolic stress and associated disorders posed by a high-cholesterol (HC) and high-galactose (HG) diet in zebrafish (Danio rerio). Adult zebrafish (n = 56\/group) were fed either with an HC+HG diet (containing 4%, w\/w cholesterol and 30%, w\/w galactose), or an HC+HG amalgamated diet with POL (final 0.1% w\/w or 0.5% w\/w). Zebrafish in the specified groups were sacrificed post-30 weeks of feeding, and blood and organs (liver, brain, and eyes) were processed for biochemical, histological, and immunohistochemical (IHC) analysis. After 30 weeks of feeding, the highest mortality (12.5%) was noticed in the HC+HG supplement group, which was reduced to 4.5% with co-supplementation of POL (0.1% and 0.5%). In a dose-dependent manner, POL significantly reversed HC+HG elevated levels of total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), glucose, and malondialdehyde (MDA), while substantially augmenting plasma high-density lipoprotein cholesterol (HDL-C), sulfhydryl content, ferric ion reduction ability (FRA), and paraoxonase (PON) activity. In addition, POL mitigated HC+HG-induced hepatomegaly, inflammation, and fatty liver changes. Consistently, POL minimizes ROS generation and cellular senescence in the brain and substantially improves HC+HG-induced cognitive changes (cessation of swimming ability and motion), with a marked ~5 times higher swimming distance. Notably, POL mitigated the HC+HG-induced corneal opacity and attenuated oxidative stress, apoptosis, 4-hydroxynonenal (4-HNE) accumulation, and myelin sheath degeneration in the retina. The findings underscore the therapeutic potential of policosanol in attenuating oxidative stress, metabolic changes, and various organ damage caused by prolonged exposure to the HC+HG diet.<\/jats:p>","DOI":"10.3390\/antiox14121453","type":"journal-article","created":{"date-parts":[[2025,12,3]],"date-time":"2025-12-03T15:02:48Z","timestamp":1764774168000},"page":"1453","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Cuban Sugarcane Wax Alcohol Supplementation Prevents Brain and Eye Damages of Zebrafish Exposed to High-Cholesterol and High-Galactose Diet for 30 Weeks: Protection of Myelin, Cornea, and Retina"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1198-4140","authenticated-orcid":false,"given":"Kyung-Hyun","family":"Cho","sequence":"first","affiliation":[{"name":"Raydel HDL Research Institute, Medical Innovation Complex, Daegu 41061, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ashutosh","family":"Bahuguna","sequence":"additional","affiliation":[{"name":"Raydel HDL Research Institute, Medical Innovation Complex, Daegu 41061, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cheolmin","family":"Jeon","sequence":"additional","affiliation":[{"name":"Raydel HDL Research Institute, Medical Innovation Complex, Daegu 41061, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sang Hyuk","family":"Lee","sequence":"additional","affiliation":[{"name":"Raydel HDL Research Institute, Medical Innovation Complex, Daegu 41061, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yunki","family":"Lee","sequence":"additional","affiliation":[{"name":"Raydel HDL Research Institute, Medical Innovation Complex, Daegu 41061, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Seung Hee","family":"Baek","sequence":"additional","affiliation":[{"name":"Raydel HDL Research Institute, Medical Innovation Complex, Daegu 41061, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chae-Eun","family":"Yang","sequence":"additional","affiliation":[{"name":"Raydel HDL Research Institute, Medical Innovation Complex, Daegu 41061, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ji-Eun","family":"Kim","sequence":"additional","affiliation":[{"name":"Raydel HDL Research Institute, Medical Innovation Complex, Daegu 41061, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Krismala","family":"Djayanti","sequence":"additional","affiliation":[{"name":"Raydel HDL Research Institute, Medical Innovation Complex, Daegu 41061, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,12,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1063","DOI":"10.1002\/iub.262","article-title":"Galactose toxicity in animals","volume":"61","author":"Lai","year":"2009","journal-title":"IUBMB Life"},{"key":"ref_2","doi-asserted-by":"crossref","unstructured":"Conte, F., van Buuringen, N., Voermans, N.C., and Lefeber, D.J.
