Evidence is lacking to support vitamin D screening or supplementation in the general population, regardless of baseline serum 25-hydroxyvitamin D levels. The National Academy of Medicine recommends that individuals 70 years and younger consume 600 IU of vitamin D daily and that individuals older than 70 years consume 800 IU daily. This can be achieved through dietary sources, supplements, or both. Achieving the recommended intake prevents serum 25-hydroxyvitamin D levels from decreasing to less than 12 ng/mL in 97.5% of the general population. Randomized controlled trials of vitamin D supplementation in the general population, including patients with low baseline serum 25-hydroxyvitamin D levels, do not demonstrate reduced all-cause mortality or improvement in cardiovascular health. Some patients with prediabetes may benefit from taking at least 3 years of vitamin D supplementation that exceeds the recommended dietary intake to reduce the risk of progression to type 2 diabetes. Randomized controlled trials of vitamin D supplementation for reducing the risk of falls and fractures, cancer, dementia, respiratory infections, and depression; for symptoms of fatigue, hair loss, and chronic pain; and during pregnancy and menopause do not show consistent benefit, including in patients with low baseline serum 25-hydroxyvitamin D levels.</p>","PeriodicalId":7713,"journal":{"name":"American family physician","volume":"114 4","pages":"381-386"},"PeriodicalIF":3.5,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149190718","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
