Tag: Spirulina nutrition

Spirulina, often called the "best food of the 21st century," offers a concentrated source of nutrients. Cultivated in tropical regions, spirulina becomes even more potent, providing a wealth of vitamins, minerals, and antioxidants essential for overall well-being.

While standard spirulina is recognized for its high mineral content, including potassium, blue spirulina is a purified extract. This extraction process significantly alters its nutritional profile, meaning it is not a significant source of potassium like its whole-algae counterpart.

According to a study published in *Chemical characterization and nutritional value of Spirulina*, this blue-green algae contains high amounts of B-complex vitamins, including B2, B3, B5, and B9. This diverse nutritional profile explains why people want to know which vitamin is found in spirulina.

The protein content in 100 grams of dried algae can range from 15 grams to over 60 grams, with popular microalgae like spirulina containing significantly more protein than many land-based plants. This wide variation means that knowing the specific type of algae is crucial for determining its exact protein density.

According to a 2025 review in *Frontiers in Nutrition*, seitan contains approximately 25 grams of protein per 100 grams, making it one of the highest protein-density foods available. But which vegan food has the highest protein when all factors are considered? The answer depends on whether you are looking for pure protein concentrate, protein per gram, or a whole-food source.
