Individuals who have an allergy to seaweed or other sea vegetables, such as kelp and dulse, should not take sea moss. Additionally, individuals with kidney disease, diabetes, or any type of thyroid disorder should avoid taking sea moss due to its high content of iodine and potassium chloride. Sea Moss may also interact with certain medications; hence those on medication should consult a healthcare professional before using it. Finally, pregnant women are typically advised against taking sea moss since its effects on the fetus are not known yet.
