In the Middle East, vitamin D deficiency is common. Therefore, this study aimed to examine the prevalence of vitamin D supplement use and associated factors among Egyptians and Jordanians. In addition, practices for maintaining adequate vitamin D levels were investigated. The study was cross-sectional and included 1,181 subjects from Jordan and Egypt. Participant recruitment was conducted from April to October 2024. The results showed that approximately one-third of the sample (36.7%) were using vitamin D supplements. Vitamin D supplementation was more prevalent among Jordanians (45.2%) than Egyptians (27.2%, P\u2009&lt;\u20090.01). Factors influencing vitamin D supplement use included female gender, high income, chronic disease, laboratory testing for vitamin D, and awareness of deficiency symptoms. Among the practices participants used to maintain adequate vitamin D levels were sun exposure (84.6%), consuming vitamin D-rich foods (79.6%), regularly monitoring the blood vitamin D levels (49.5%), and using vitamin D supplements (36.7%). The internet, university\/school curricula, and healthcare providers were the main sources of information related to vitamin D. In conclusion, vitamin D supplementation is common among study participants and is associated with several factors. The study findings can inform interventions aimed at managing vitamin D deficiency\/insufficiency in the region.<\/jats:p>","DOI":"10.1371\/journal.pone.0357029","type":"journal-article","created":{"date-parts":[[2026,8,28]],"date-time":"2026-08-28T17:27:36Z","timestamp":1787938056000},"page":"e0357029","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":0,"title":["Vitamin D supplement use in Egypt and Jordan and associated factors: A survey-based study"],"prefix":"10.1371","volume":"21","author":[{"given":"TaqiAldeen","family":"Khabour","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3006-3104","authenticated-orcid":true,"given":"Omar F.","family":"Khabour","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Salwa F.
