Quick answer

What to know
Spirulina and chlorella are separate ingredients. They differ in biology, nutrient profile, processing, and label amount. Avoid treating the names as interchangeable. When spirulina appears inside a multi-ingredient blend, review the serving size and whether the label gives an individual amount. Product quality also depends on sourcing and testing, not the ingredient name alone.
Source / Origin
