These developments, combined with the expanding applications of diagnostic imaging in healthcare, continue to drive the demand for iodine-based contrast media.

Growing Iodine Deficiency Among People

Iodine deficiency remains a significant global health concern, driving the demand for iodine supplements across various applications. The World Health Organization has identified iodine deficiency as the primary cause of preventable brain damage worldwide, affecting over two billion people globally. This widespread deficiency has led to increased implementation of iodine supplementation programs, particularly through Universal Salt Iodization (USI) initiatives. The Institute of Medicine has established specific Recommended Dietary Allowances (RDA) for iodine, with adult men and women requiring 150 µg per day, while pregnant women need 220 µg per day, and lactating mothers require 290 µg per day, highlighting the critical importance of adequate iodine nutrition across different population segments.

The growing awareness of iodine deficiency's impact on public health has led to increased governmental and organizational initiatives to address this issue. As of 2021, more than 120 countries have implemented mandatory salt iodization legislation, while 21 countries have voluntary iodization programs, resulting in increased consumption of iodine salt worldwide. This is reflected in the significant household consumption rates of iodized salt across various regions, with East Asia and the Pacific reaching 92%, South Asia at 89.9%, and West and Central Asia at 83.3%. The American Thyroid Association's recommendation for all women considering pregnancy, pregnant women, or breastfeeding mothers to take prenatal multivitamins containing 150 µg of iodine further emphasizes the growing recognition of iodine's importance in public health.
