The aim of this study was to assess the effects of multivitamin supplementation in older adults on cognitive function and associated blood biomarkers. In a randomised, double blind, placebo-controlled trial, healthy women (n = 68) and men (n = 48) aged 55\u201365 years were supplemented daily for 16 weeks with  women\u2019s and men\u2019s formula multivitamin supplements. Assessments at baseline and  post-supplementation included computerised cognitive tasks and blood biomarkers relevant to cognitive aging. No cognitive improvements were observed after supplementation with either formula; however, several significant improvements were observed in blood biomarkers including increased levels of vitamins B6 and B12 in women and men; reduced C-reactive protein in women; reduced homocysteine and marginally reduced oxidative stress in men; as well as improvements to the lipid profile in men. In healthy older people, multivitamin supplementation improved a number of blood biomarkers that are relevant  to cognition, but these biomarker changes were not accompanied by improved  cognitive function.<\/jats:p>","DOI":"10.3390\/nu7053796","type":"journal-article","created":{"date-parts":[[2015,5,19]],"date-time":"2015-05-19T10:35:57Z","timestamp":1432031757000},"page":"3796-3812","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":22,"title":["Improved Blood Biomarkers but No Cognitive Effects from  16 Weeks of Multivitamin Supplementation in Healthy  Older Adults"],"prefix":"10.3390","volume":"7","author":[{"given":"Elizabeth","family":"Harris","sequence":"first","affiliation":[{"name":"Centre for Human Psychopharmacology, Swinburne University of Technology, Hawthorn,  VIC 3122, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Helen","family":"Macpherson","sequence":"additional","affiliation":[{"name":"Centre for Human Psychopharmacology, Swinburne University of Technology, Hawthorn,  VIC 3122, Australia"},{"name":"Centre for Physical Activity and Nutrition Research, School of Exercise and Nutrition Sciences, Deakin University, Burwood, VIC 3125, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrew","family":"Pipingas","sequence":"additional","affiliation":[{"name":"Centre for Human Psychopharmacology, Swinburne University of Technology, Hawthorn,  VIC 3122, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2015,5,19]]},"reference":[{"key":"ref_1","first-page":"132","article-title":"Iana task force on nutrition and cognitive decline with aging","volume":"11","author":"Andrieu","year":"2007","journal-title":"J.
