Which alga is high in iodine and fiber and a good source of vitamin C?

• A. Brown Algae
• B. Green Algae
• C. Red Algae
• D. Blue-Green Algae

Answer: (A)

Brown algae stand out because they naturally accumulate large amounts of iodine from seawater, making them one of the richest natural sources of dietary iodine. They also contain substantial dietary fiber in the form of alginates, which act as soluble fiber and support gut health. In addition, they provide vitamin C, especially when fresh or minimally processed, so they can contribute to daily vitamin C intake as well. The combination of very high iodine, meaningful fiber content, and vitamin C is characteristic of brown seaweeds like kelp and wakame, which is why they are the best-fit choice. Green, red, and blue-green algae generally don’t offer as much iodine or the same fiber profile, and their vitamin C content varies more, making brown algae the strongest match for all three traits.
