IGN's mission is to "be the authoritative voice for iodine nutrition." Their mission states:
"We support and catalyze global and national iodine programs, working with key public, private, scientific and civic stakeholders. We focus on universal salt iodization as the most cost-effective and sustainable solution for prevention of iodine deficiency disorders."
