Sea moss: A nutrient-packed superfood with surprising health perks and risks

Sea moss, also called Irish sea moss or red seaweed, is a marine vegetable that grows along the rocky Atlantic coasts between North America and Europe. Known scientifically as Chondrus crispus, it is often used for its rich content of vitamins, minerals, and antioxidants. Sea moss is a natural source of iodine, which supports thyroid health. It also provides a range of minerals, including iron, magnesium, phosphorus, zinc, and copper. A single serving of raw Irish sea moss contains just 10 calories and 0.5 grams of protein.

The plant is the only natural source of carrageenan, a thickener commonly used in foods such as ice cream, cottage cheese, and baby formula. Many people take sea moss as a supplement to boost overall health. Potential benefits may include support for thyroid function, immunity, gut health, weight loss, heart health, and blood sugar management, though more research is required to confirm these effects.

At home, sea moss gel can be made by soaking raw sea moss in water overnight and blending it with fresh water until smooth. However, consuming it in large amounts may cause side effects. It may also be unsafe for individuals with hypothyroidism or allergies to seaweed. Sea moss offers a variety of nutrients and possible health benefits. It is widely used in supplements and food production. Still, caution is advised due to potential risks for certain individuals.
