Sea moss supplements are not regulated by the FDA and can vary widely in iodine content and purity, posing health risks.

Because sea moss supplements are not FDA-approved, their iodine levels and potential contamination with heavy metals like mercury or lead can vary dramatically. This lack of regulation means consumers risk ingesting unsafe doses or pollutants, which can damage organs such as the kidneys and nervous system, especially if the sea moss is harvested from polluted waters.
