It was recently reported in mice that miscarriage can be prevented through the administration of niacin. We conducted a prospective, exploratory pilot study involving 24 women who were less than 14\u00a0weeks pregnant. Neither niacin intake (<jats:italic>P<\/jats:italic>\u00a0=\u00a00.24) nor urinary vitamin B3 measured as the 1\u2010methyl\u20105\u2010carboxylamide\u20102\u2010pyridone\/<jats:italic>N<\/jats:italic>\u20101\u2010methylnicotinamide (2\u2010pyr\/MNA) ratio (<jats:italic>P<\/jats:italic>\u00a0=\u00a01.00) predicted miscarriage. However, the difference in mean 2\u2010pyr\/MNA ratios between women who miscarried and controls suggests there may be a threshold niacin level protective in miscarriage prevention warranting further investigation.<\/jats:p>","DOI":"10.1111\/ajo.13341","type":"journal-article","created":{"date-parts":[[2021,4,18]],"date-time":"2021-04-18T17:00:42Z","timestamp":1618765242000},"page":"478-483","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Vitamin B3 levels in women who experience first\u2010trimester miscarriage"],"prefix":"10.1111","volume":"61","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8976-125X","authenticated-orcid":false,"given":"Nurul A.","family":"Yakob","sequence":"first","affiliation":[{"name":"ANU Medical School Australian National University Canberra Australian Capital Territory Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael J.","family":"Peek","sequence":"additional","affiliation":[{"name":"ANU Medical School Australian National University Canberra Australian Capital Territory Australia"},{"name":"Obstetrics and Gynaecology The Canberra Hospital Canberra Australian Capital Territory Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4706-2412","authenticated-orcid":false,"given":"Julie A.","family":"Quinlivan","sequence":"additional","affiliation":[{"name":"ANU Medical School Australian National University Canberra Australian Capital Territory Australia"},{"name":"Obstetrics and Gynaecology University of Notre Dame Fremantle Western Australia Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2021,4,18]]},"reference":[{"key":"e_1_2_7_2_1","first-page":"283","article-title":"Early pregnancy bleeding","volume":"45","author":"Breeze C","year":"2016","journal-title":"Aust Fam Physician"},{"key":"e_1_2_7_3_1","first-page":"CD004073","article-title":"Vitamin supplementation for preventing miscarriage","volume":"5","author":"Balogun OO","year":"2016","journal-title":"Cochrane Database Syst Rev"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1136\/bmjopen-2016-011382"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00737-017-0742-9"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1002\/nur.20389"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-3999(03)00042-4"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1744-4667.2012.00116.x"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa1616361"},{"key":"e_1_2_7_10_1","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.1614947113"},{"key":"e_1_2_7_11_1","unstructured":"USDA Food Composition Databases[Accessed 1 Aug 2019.] Available from URL:https:\/\/ndb.nal.usda.gov\/ndb\/"},{"key":"e_1_2_7_12_1","unstructured":"Eat This Much Food & Recipe Browser.Eat This Much.
