Do Iron and L. plantarum 299v interact?: More absorbed iron per milligram taken, with better tolerability — potentially allowing a lower iron dose. The tolerability finding comes from an open-label trial, so treat its size as provisional. Note it did NOT improve on ferrous sulfate alone in iron-deficient children.
