Why Iodine Is Essential for Thyroid Health and Pregnancy
Iodine is an essential nutrient required for the synthesis of thyroid hormones, playing a critical role in normal thyroid function at all stages of life. Adequate iodine intake is especially important for women of childbearing age and is even more crucial during pregnancy, as the developing fetus relies entirely on the mother’s thyroid hormones for physical growth and brain and neurological development.
Iodine Needs During Pregnancy
During pregnancy, iodine requirements increase due to higher demands on thyroid function to support fetal growth and development. Pregnant women also experience increased urinary iodine excretion, which can further reduce iodine levels if intake is inadequate.
The Institute of Medicine (IOM) recommends 220 mcg of iodine per day for pregnant women, while the U.S. Food and Drug Administration (FDA) recommends 150 mcg per day for both pregnant and non-pregnant women.
Why Shaklee Uses 200 mcg of Iodine
The Shaklee science team selected 200 mcg of iodine per serving for Shaklee Vitalizer Women and Vita-Lea® Iron Formula. This amount represents an intermediate level between IOM and FDA recommendations and is designed to support the needs of women throughout their reproductive years.
Scientific Rationale Behind the Iodine Level
-
Iodine needs increase during pregnancy to support fetal development and maintain maternal thyroid function
-
Dietary iodine intake has declined in recent years in both U.S. and global populations, including pregnant women and women of childbearing age
-
The established upper limit (UL) for iodine intake is 1,100 mcg per day for adults, making the iodine level in Vitalizer Women and Vita-Lea® Iron Formula a safe and effective option
This thoughtfully chosen iodine level helps support adequate intake while remaining well within established safety guidelines.
