Spirulina comes in green and a striking blue. Here is the honest blue spirulina vs green comparison.
Green spirulina
The whole algae — protein-dense, with polysaccharides whose functional groups help bind heavy metals like lead and mercury.
Blue spirulina
A concentrated extract of phycocyanin, the blue pigment, prized for antioxidant support.
Why both beats either
Green brings the binding and protein; blue brings the antioxidant pigment. Few formulas carry both — SPIRO Plus uses dual spirulina (green + blue extract) alongside 17 enzymes and chlorella.
