Sea moss contains iodine, which is essential for thyroid hormone production but can cause thyroid dysfunction if consumed in excess.

Sea moss is a natural source of iodine, a critical mineral for thyroid hormone synthesis. However, excessive intake of iodine from sea moss supplements can lead to thyroid problems such as hyperthyroidism, hypothyroidism, or goiter. Individuals with thyroid conditions are especially at risk and should consult their doctor before using sea moss regularly.
