What Are Spirulina and Chlorella?
Spirulina and chlorella are two of nature’s most nutrient-dense foods. These microscopic algae have been consumed for centuries and are now recognized as powerful superfoods backed by modern science.
Spirulina is a blue-green algae (cyanobacteria) that grows in both fresh and saltwater. It was consumed by ancient Aztecs and has been used by NASA as a dietary supplement for astronauts.
Chlorella is a single-celled green algae found in freshwater. It’s known for its unique ability to bind to heavy metals and support the body’s natural detoxification processes.
