Choline requirements are linked to age and genetics, folate and cobalamin via betaine, and arachidonic (ARA) and docosahexaenoic (DHA) acid transport via the phosphatidylcholine moiety of lipoproteins. Groups at risk of choline deficiency include preterm infants, children with cystic fibrosis (CF) and patients dependent on parenteral nutrition. Fortifiers, formula and supplements may differently impact their choline supply. Objective: To evaluate added amounts of choline, folate, cobalamin, ARA and DHA in fortifiers, supplements and formula used in pediatric care from product files. Methods: Nutrient contents from commonly used products, categorized by age and patient groups, were obtained from public sources. Data are shown as medians and interquartile ranges. Results: 105 nutritional products including fortifiers, formula and products for special indications were analyzed. Choline concentrations were comparable in preterm and term infant formulas (\u22646 months) (31.9 [27.6\u201333.3] vs. 33.3 [30.8\u201335.2] mg\/100 kcal). Products for toddlers, and patients with CF, kidney or Crohn\u2019s disease showed Choline levels from 0 to 39 mg\/100 kcal. Several products contain milk components and lecithin-based emulsifiers potentially increasing choline content beyond indicated amounts. Conclusions: Choline addition is standardized in formula for term and preterm infants up to 6 months, but not in other products. Choline content may be higher in several products due to non-declared sources. The potential impact of insufficient choline supply in patients at risk for choline deficiency suggests the need for biochemical analysis of products.<\/jats:p>","DOI":"10.3390\/nu17101632","type":"journal-article","created":{"date-parts":[[2025,5,9]],"date-time":"2025-05-09T11:25:53Z","timestamp":1746789953000},"page":"1632","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Choline in Pediatric Nutrition: Assessing Formula, Fortifiers and Supplements Across Age Groups and Clinical Indications"],"prefix":"10.3390","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0307-223X","authenticated-orcid":false,"given":"Wolfgang","family":"Bernhard","sequence":"first","affiliation":[{"name":"Department of Neonatology, University Children\u2019s Hospital T\u00fcbingen, Faculty of Medicine, Eberhard-Karls-University, 72076 T\u00fcbingen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anna","family":"Shunova","sequence":"additional","affiliation":[{"name":"Department of Neonatology, University Children\u2019s Hospital T\u00fcbingen, Faculty of Medicine, Eberhard-Karls-University, 72076 T\u00fcbingen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ute","family":"Graepler-Mainka","sequence":"additional","affiliation":[{"name":"Department of General Pediatrics, Hematology & Oncology, University Children\u2019s Hospital T\u00fcbingen, Faculty of Medicine, Eberhard-Karls-University, 72076 T\u00fcbingen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-0055-7452","authenticated-orcid":false,"given":"Johannes","family":"Hilberath","sequence":"additional","affiliation":[{"name":"Department of Pediatric Gastroenterology and Hepatology, University Children\u2019s Hospital T\u00fcbingen, Faculty of Medicine, Eberhard-Karls-University, 72076 T\u00fcbingen, Germany"},{"name":"Department of Hematology and Oncology, University Children\u2019s Hospital T\u00fcbingen, Faculty of Medicine, Eberhard-Karls-University, 72076 T\u00fcbingen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6850-6249","authenticated-orcid":false,"given":"Cornelia","family":"Wiechers","sequence":"additional","affiliation":[{"name":"Department of Neonatology, University Children\u2019s Hospital T\u00fcbingen, Faculty of Medicine, Eberhard-Karls-University, 72076 T\u00fcbingen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1072-0066","authenticated-orcid":false,"given":"Christian F.","family":"Poets","sequence":"additional","affiliation":[{"name":"Department of Neonatology, University Children\u2019s Hospital T\u00fcbingen, Faculty of Medicine, Eberhard-Karls-University, 72076 T\u00fcbingen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5066-0857","authenticated-orcid":false,"given":"Axel R.","family":"Franz","sequence":"additional","affiliation":[{"name":"Department of Neonatology, University Children\u2019s Hospital T\u00fcbingen, Faculty of Medicine, Eberhard-Karls-University, 72076 T\u00fcbingen, Germany"},{"name":"Center for Pediatric Clinical Studies, University Children\u2019s Hospital T\u00fcbingen, Faculty of Medicine, Eberhard-Karls-University, 72076 T\u00fcbingen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,5,9]]},"reference":[{"key":"ref_1","unstructured":"(1998).
