Potential benefits but need more evidence
Seaweed, also known as red algae, is a source of protein, minerals and beneficial plant compounds. According to pharmacist Ross Phan, initial studies show that seaweed can support health in many ways.
First of all, seaweed can support digestion thanks to its prebiological properties, helping to nourish beneficial intestinal bacteria. However, carrageenan in seaweed can also worsen inflammatory bowel disease in some people.
With the thyroid gland, seaweed is rich in iodine, an essential factor in producing metabolic hormones. However, supplementing too much can cause thyroid dysfunction.
Some animal studies show that seaweed helps boost immunity, but also has the potential to cause inflammation or allergic reactions.
In addition, antioxidants in seaweed are recorded to have anti-cancer potential, although evidence is currently limited to laboratory research.
Seaweed is also of interest for its ability to prevent HPV viruses, thanks to the antiviral properties of carrageenan. In addition, some initial studies show that it can prevent blood clots and support diabetes control, but more clinical data is needed.

Besides the benefits, seaweed also contains many risks. High iodine content can cause iodine poisoning, with symptoms such as nausea, diarrhea, and even heart disorders. In addition, the risk of allergies, prolapsed enterocolitis, or heavy metal contamination such as lead and mercury should also be noted.
According to clinical nutritionist Melissa Nieves - working in the US: "Seaweeds can bring benefits, but should not be seen as a treatment solution. Use should be based on medical advice, especially for people with underlying diseases.
Groups such as pregnant women, people with thyroid disease, the elderly or children should be cautious. There are currently no official dosage recommendations, but about 3 to 4 grams of dried seaweed per day is considered a relatively safe level.
