Spirulina is 60% to 70% protein by weight—more than beef or eggs. But it’s also a complete protein, meaning it has all nine essential amino acids. Take that, steak!
It contains antioxidants like phycocyanin, which gives it that bluish tint. This compound is so powerful it’s used in lab research to fight inflammation. Basically, spirulina is a tiny pharmacy in a pond.
And get this: astronauts have grown spirulina in space! Yep, NASA has studied it for long-term missions. If it’s good enough for floating humans, it’s probably okay for your brownie batter.
