# Progressive-Release Iron Fortifiers Lallemand Develops Yeast-Based Iron To Ease Digestive Discomfo By Ellen Smith | Written with AI assistance | Published 2026-10-17 | Lifestyle Source: Trend Hunter, https://www.trendhunter.com/trends/progressive-release-iron-fortifiers References: [nutritioninsight](https://www.nutritioninsight.com/news/lallemand-lalmin-iron-nutritional-yeast.html)  Lallemand Bio-Ingredients is expanding iron ingredients with Lalmin Iron, a nutritional yeast for formulators that stores iron inside a yeast matrix and releases it gradually during digestion instead of delivering it as a conventional salt. The approach targets an adherence problem in [iron supplementation](https://www.trendhunter.com/trends/ritual-iron-bioseries), especially for [athletic women](https://www.trendhunter.com/trends/gender-disparities-in-sports-nutrition), who face higher deficiency risk and often stop taking products that upset the gut. In a pilot study, 14 physically active women used cookies fortified with Lalmin Iron for two weeks. The regimen delivered 40 mg of iron in total, and researchers found no rise in gastrointestinal symptoms alongside lower constipation and diarrhea scores. Gradual release from a yeast matrix gives supplement companies a clearer way to address the stomach issues that often derail repeat use. The [cookie-based pilot](https://www.trendhunter.com/trends/enzymedica) also widens where this kind of iron fits, from capsules to food-inspired formats that feel less clinical.
