In my experience working with patients concerned about hormonal balance and fatigue, thyroid health often becomes a key topic of discussion. While sea moss is not a medical treatment, some patients are interested in foods that contain natural iodine. I usually remind them that iodine is important for normal thyroid hormone production, but balance is essential.
From a nursing perspective, I encourage patients to focus on moderate intake and consult their healthcare provider, especially if they already have a thyroid condition.
