Over 10,000 species are classified as seaweed, a broad category that includes kelp. Understanding the biological and nutritional differences between these marine superfoods is key to determining which might be better for your specific dietary and health goals. While all edible seaweeds offer impressive health benefits, kelp stands out for its high iodine content and role in vital ocean ecosystems.

While some dried seaweed products may contain a significant percentage of carbohydrates by dry weight, the vast majority of these carbs are indigestible dietary fiber, making seaweed very low in net carbs. The key to answering the question, 'Is seaweed a high carb?' lies in understanding the difference between total carbohydrates and net carbohydrates.

Often called "longevity seaweed" in Okinawa, Japan, sea grapes (*Caulerpa lentillifera*) are a highly prized edible algae celebrated for their unique texture and impressive nutritional value. This marine superfood offers a wealth of vitamins, minerals, and bioactive compounds that support overall health and wellness.

While vitamin B12 is essential for nerve function and red blood cell production, it is most readily found in animal products. This has led many plant-based eaters to ask: can you get enough B12 from seaweed? Emerging research, particularly on purple laver (nori), suggests it may be a viable source for some, though consistency remains a concern.
