Overview
This is a blue spirulina powder made from phycocyanin extract, sold as USDA organic certified in a 1 ounce, 28-serving pouch. The pitch is a fishy-smell-free, vegan protein source doubling as a natural blue food coloring.
Blue spirulina (phycocyanin) is prized less for taste, since it's sold unflavored, and more for its natural blue-green pigment in smoothies, baked goods and drinks, which is the actual use case the title leads with. USDA organic certification is the main quality marker given here, and no third-party testing or heavy metal screening claims appear in the data provided.
- USDA organic phycocyanin extract
- Unflavored blue spirulina powder
- 28 servings, 1 ounce pouch
- Marketed for natural food coloring
Who it's for
Home bakers and smoothie makers wanting a natural food coloring alternative to synthetic dyes, and buyers specifically avoiding the fishy smell some spirulina powders have. Not the product for someone shopping for a high-dose spirulina protein or nutrient supplement, since portioning here is coloring-oriented at 28 servings per ounce.
