Folic acid fortification of iodized salt improves the folate status of nonpregnant adult Ethiopian females and does not impair their iodine status: a community-based, household-randomized, dose-response trial

Key Points

• Improved folate status was observed in nonpregnant adult Ethiopian females after fortification with folic acid.
• The trial revealed no adverse effects on iodine status, maintaining appropriate levels among participants.
• Community-based, household-randomized dose-response trial assessed the impact of fortification on folate and iodine levels.
• Findings imply the fortification could be an effective public health strategy to address nutritional deficiencies.
