The unique nutritional profile, along with a rich content of soluble fiber and bioactives, has led to growing interest in the potential of seaweeds in addressing micronutrient insufficiencies, particularly in plant\u2010based diets where traditional sources of certain micronutrients are limited. This study aimed to evaluate selected Scottish seaweed species by quantifying key micronutrients and estimating their potential contribution to dietary intakes while also determining heavy metal and iodine concentrations to assess consumer exposure risk. In addition, the study investigated practical mitigation strategies to reduce iodine and heavy metal levels, with the objective of delivering nutritionally valuable seaweed products that are both safe and aligned with dietary guidelines. Eleven wild seaweed species obtained from the north coast of Scotland together with two farmed seaweed species from the west coast were analyzed for mineral and heavy metal content using inductively coupled plasma\u2013mass spectrometry (ICP\u2010MS), and vitamin B\n 12<\/jats:sub>\n content by an enzyme\u2010linked immunosorbent assay. Seaweed iodine and heavy metal content were used to assess potential health risks. Additionally, some seaweed species were subjected to a blanching process in water heated at different temperatures to assess the effects on reducing seaweed iodine and heavy metal content. All wild and farmed Scottish seaweeds contained detectable levels of vitamin B\n 12<\/jats:sub>\n , with the highest content observed in\n Fucus<\/jats:italic>\n species, with\n \n F. serratus<\/jats:italic>\n <\/jats:styled-content>\n showing a mean value of 148.0\u2009\u00b1\u200942.5\u2009\u03bcg\/kg dry weight. This was estimated to potentially provide 49% of the RNI for vitamin B\n 12<\/jats:sub>\n in a 5\u2009g portion. Among the minerals analyzed, a 5\u2009g portion of seaweed was estimated to provide notable amounts of the RNI for potassium (up to 18%), magnesium and calcium (around 10%), and iron (up to 83%), but these were dependent on seaweed species or whether farmed or not. Most seaweeds, however, contained high iodine levels that were estimated to pose a risk to health. Blanching of\n \n A. esculenta<\/jats:italic>\n <\/jats:styled-content>\n ,\n S. latissima<\/jats:italic>\n , and\n \n F. serratus<\/jats:italic>\n <\/jats:styled-content>\n for 5\u2009min at 80\u00b0C showed that seaweed iodine content could be reduced by around up to 90% in all three species, while in the latter two species it additionally reduced levels of arsenic by 39% and 52%, respectively. Scottish seaweeds show strong potential as sustainable sources of essential micronutrients, particularly for populations who do not consume animal products, such as vegetarians. However, the bioavailability of vitamin B\n 12<\/jats:sub>\n was not assessed in this study and should be examined in future work. In addition, heavy metal concentrations must remain within safe limits to minimize potential health risks. Therefore, future studies should focus on optimizing harvesting and processing methods to ensure health risks are minimized while the nutritional benefits are optimized.\n <\/jats:p>","DOI":"10.1002\/fsn3.71988","type":"journal-article","created":{"date-parts":[[2026,6,5]],"date-time":"2026-06-05T04:14:53Z","timestamp":1780632893000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Scottish Seaweeds as Sustainable Sources of Micronutrients: Mineral Composition, Vitamin\n \n B\n 12<\/sub>\n <\/scp>\n Content, and Safety Assessment"],"prefix":"10.1002","volume":"14","author":[{"given":"Ibrahim","family":"Almosa","sequence":"first","affiliation":[{"name":"The Rowett Institute University of Aberdeen Aberdeen UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shabina","family":"Bashir","sequence":"additional","affiliation":[{"name":"The Rowett Institute University of Aberdeen Aberdeen UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alan A.","family":"Sneddon","sequence":"additional","affiliation":[{"name":"The Rowett Institute University of Aberdeen Aberdeen UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,6,4]]},"reference":[{"key":"e_1_2_11_2_1","doi-asserted-by":"publisher","DOI":"10.29219\/fnr.v65.7584"},{"key":"e_1_2_11_3_1","first-page":"563","article-title":"Bioavailability of Seaweed Iodine in Human Beings","volume":"48","author":"Aquaron R.","year":"2002","journal-title":"Cellular and Molecular Biology"},{"key":"e_1_2_11_4_1","doi-asserted-by":"publisher","DOI":"10.1111\/1541-4337.12523"},{"key":"e_1_2_11_5_1","doi-asserted-by":"publisher","DOI":"10.1111\/1541-4337.12918"},{"key":"e_1_2_11_6_1","doi-asserted-by":"publisher","DOI":"10.1093\/nutrit\/nuy066"},{"key":"e_1_2_11_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.fct.2021.112385"},{"key":"e_1_2_11_8_1","doi-asserted-by":"publisher","DOI":"10.1093\/ajcn\/53.3.695"},{"key":"#cr-split#-e_1_2_11_9_1.1","unstructured":"EC Commission.2014.\"Regulation No. 488\/2014 of 12 May 2014 Amending Regulation"},{"key":"#cr-split#-e_1_2_11_9_1.2","unstructured":"(EC) No. 1881\/2006 as Regards Maximum Levels of Cadmium in Foodstuffs (Text With EEA Relevance).
