19 Jun 2019 --- A probiotic concept containing Lactobacillus plantarum 299v and a mix of vitamin C, folic acid and iron, Probi FerroSorb, has been found to improve the iron status of pregnant women significantly. Iron deficiency is the most common nutrient deficiency in the world and is especially common during pregnancy. However, Probi, who developed the concept, notes that common iron supplements can cause unpleasant side effects such as abdominal pain and constipation. These findings support the further development of probiotic concepts targeting pregnancy, which may reduce iron deficiency levels without unpalatable side effects.
