Synopsis

Source of validity: Scientific
Rating (out of 5): 4

Iodine plays a critical role in supporting the reproductive system, with its use justified by scientific evidence. Iodine is an essential micronutrient required for the synthesis of thyroid hormones (thyroxine/T4 and triiodothyronine/T3), which regulate numerous physiological processes, including reproductive health. In women, thyroid hormones are crucial for normal ovarian function, menstrual regularity, and fertility. Iodine deficiency can lead to hypothyroidism, which is strongly associated with menstrual disturbances, ovulatory dysfunction, infertility, and increased risk of miscarriage and adverse pregnancy outcomes. During pregnancy, sufficient iodine is vital for fetal neurodevelopment and the maintenance of maternal thyroid function.

Multiple studies and reviews, including those by the World Health Organization (WHO), confirm that iodine supplementation in iodine-deficient populations improves reproductive outcomes and reduces the risk of complications such as cretinism, miscarriage, and stillbirth. The American Thyroid Association also recommends adequate iodine intake for women of childbearing age, especially during preconception and pregnancy. While iodine is not typically used as a direct fertility supplement, its fundamental role in thyroid hormone synthesis and, consequently, reproductive health is well established. However, in populations with adequate iodine intake, additional supplementation does not further enhance reproductive outcomes, which is why the rating is not the highest possible.
