2. Spirulina: The Blue-Green Algae with a Punch

Spirulina, a type of blue-green algae, is a nutritional powerhouse that has been consumed for centuries due to its health benefits. It is incredibly high in protein, containing all the essential amino acids, which makes it an excellent source of plant-based protein. Spirulina is also rich in vitamins B1, B2, and B3, as well as copper and iron, supporting energy production and immune function. The presence of powerful antioxidants like phycocyanin helps to combat oxidative stress and inflammation. Spirulina is typically available in powder or tablet form, and it can be easily added to smoothies, juices, or even sprinkled over salads for a nutritional boost.
