Spirulina
Blue-Green Algae, Arthrospira
Spirulina is a nutrient-dense blue-green algae (cyanobacteria) that has been consumed for centuries and is now recognized as a complete protein source. It thrives in alkaline freshwater environments and is harvested, dried, and sold as a supplement. Spirulina contains nearly all essential amino acids, making it valuable for vegetarians and vegans seeking complete protein.
Chlorella
Chlorella Algae, Chlorella Pyrenoidosa
Chlorella is a single-celled green freshwater alga rich in chlorophyll, protein, and micronutrients. It is notably higher in chlorophyll content than spirulina, giving it its distinctive green color. Chlorella contains a cell wall that must be broken down for nutrient absorption; reputable supplements use 'broken-cell-wall' processing to enhance bioavailability.
Supplement Safety
Dietary supplements are not regulated by the FDA in the same way as prescription medications. Always consult with your healthcare provider before starting any supplement, especially if you are pregnant, nursing, taking medications, or have a medical condition. Supplements can interact with medications and may not be safe for everyone.
