On average, participants consumed two (2.0\u2009\u00b1\u20091.36) supplements concurrently. Most multiple micronutrient supplements (MMS) contained folic acid (100%) and iodine (86.2%) at recommended doses, other nutrients varied considerably. Participants knew two (1.81\u2009\u00b1\u20091.43) out of six micronutrients prior to information provision, increasing to three (2.94\u2009\u00b1\u20091.65) afterwards. Satisfaction with information (SIMS-D: 7.46\u2009\u00b1\u20095.92) was low, whereas adherence was high (MARS-D: 27.16\u2009\u00b1\u20093.06). Higher information satisfaction was associated with pregnancy (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.007), younger age (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.009), and lower educational level (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.024).
