Frequently Asked Questions
What does spirulina taste like?
On its own, spirulina has a mild seaweed-like, slightly earthy flavor. The good news: it virtually disappears in a fruit smoothie — banana, mango, or pineapple easily mask the taste while you still get the deep green color and nutrients.
How do people usually use spirulina?
The classic use is a spoonful blended into a morning smoothie or fresh juice. Some people stir it into coconut water or lemonade, and it can also be added to energy balls, salad dressings, or guacamole for a nutrient boost and a striking green color.
Why is spirulina so intensely green?
The color comes from chlorophyll plus a blue pigment called phycocyanin, which is unique to blue-green algae. That vivid green is actually a sign of its rich pigment and antioxidant content — the deeper the green, the fresher the powder.
What's the difference between spirulina and chlorella?
Both are nutrient-dense green algae, but spirulina has no hard cell wall, which many people find makes it easier to digest. Chlorella is higher in chlorophyll and is often chosen for cleansing-style routines. They can even be used together, and many people pick based on taste and how their body responds.
Did you know? NASA has studied spirulina as a potential nutrient-dense food for astronauts on long-duration space missions, thanks to its concentrated protein, vitamins, and minerals (source: NASA).
