Iodine - Wikipedia

Iodine is a chemical element with the symbol I and atomic number 53. The heaviest of the stable halogens, it exists as a lustrous, purple-black non-metallic solid at standard conditions that melts to form a deep violet liquid at 114 degrees Celsius, and boils to a violet gas at 184 degrees Celsius.However, it readily sublimes with gentle heat, resulting in a widespread misconception even ...

Iodine - Health Professional Fact Sheet

5/1/2020 · According to the WHO, a median urinary iodine concentration of 150–249 mcg/L indicates adequate iodine nutrition during pregnancy, while values less than 150 mcg/L are considered insufficient [3,7]. Analyses of NHANES datasets from 2003 to 2014 indicate that a substantial portion of pregnant women in the United States are iodine insufficient.

Effects of feed iodine concentrations and milk processing ...

On day 21, we evaluated the dose–response relationship between feed iodine concentration and each dependent variable (MIC, total milk iodine, total iodine intake, feed-to-milk iodine transfer, milk yield, TSH and T 4) by computing an adjusted R 2 from regression analysis. For MIC only, we provided a model for the prediction of MIC as a ...
