Seaweed

Algae are a significant source of nutrients and are considered one of the healthiest foods in the world. They are rich in vitamins, minerals, fiber, and antioxidants, which can contribute to overall health and the prevention of certain diseases. They contain high amounts of iodine, which is essential for the proper functioning of the thyroid gland, and are also one of the few plant sources of omega-3 fatty acids, which are crucial for heart and brain health.

Furthermore, certain types of algae, such as spirulina and chlorella, are excellent sources of protein and can be beneficial for vegetarians and vegans. Algae also contain unique compounds, such as fucoidans and fucoxanthins, which have anti-inflammatory and anti-cancer effects. Additionally, algae are low in calories and may aid in weight loss by promoting a feeling of fullness.

Hello,

I am curious to know whether it is possible to overdose on iodine from natural sources (recently, I have developed a taste for dried nori seaweed, which seems like a great alternative to chips, but I found a recommended dose on the back of max. 3 pieces per day; otherwise, there is a risk of iodine overdose)? And what would be the symptoms of an overdose?

Thank you for your response.

Overdosing on iodine is a rare occurrence. The element binds to salts that are water-soluble—organisms have mechanisms to eliminate its excess. If you do not suffer from hyperthyroidism, a higher intake of iodine should not be a problem (at least not on a short-term basis).
