💙 Blue Spirulina

Phycocyanin extract—vibrant blue pigment, antioxidant properties, and natural food coloring.

Overview

Blue spirulina is a concentrated extract of phycocyanin, the vivid blue-green pigment found in spirulina algae. Unlike regular spirulina powder (which is dark green), blue spirulina isolates the phycocyanin compound, resulting in a vibrant blue powder with a milder taste. It's popular as a natural food colorant and for its antioxidant properties.

Key nutrition highlights

Phycocyanin: potent blue pigment-protein complex with antioxidant activity.
Protein content: concentrated protein source (though used in small amounts).
Antioxidants: supports cellular defense against oxidative stress.
Natural colorant: vibrant blue without synthetic dyes.
Mild taste: less "algae" flavor compared to regular spirulina.

Blue spirulina is an extract—it's more concentrated than whole spirulina but typically used in smaller quantities.

Typical origins & sourcing

Blue spirulina is extracted from spirulina algae cultivated in controlled environments. Prioritize:

Cold-Processed Spirulina: Look for gently cold-processed to preserve heat-sensitive nutrients like Phycocyanin for mitochondrial support
Source quality: extracted from high-quality spirulina (preferably organic).
Pure phycocyanin: check for concentration percentage and purity.
No additives: avoid products with fillers or artificial ingredients.
Third-party testing: verification of purity and absence of contaminants.
Cultivation location: spirulina grown in clean, controlled environments (USA, Taiwan, Hawaii).
Extraction method: cold-water extraction preserves phycocyanin integrity.
Color intensity: vibrant blue indicates high phycocyanin content.

Price note: Blue spirulina is more expensive than regular spirulina due to extraction process.

❓ FAQ: Blue Spirulina

What's the difference between blue spirulina and regular spirulina?

Regular spirulina is the whole dried algae (dark green color, strong "algae" taste). Blue spirulina is an extract containing only the phycocyanin pigment (bright blue color, milder taste). Regular spirulina offers broader nutritional profile; blue spirulina offers concentrated antioxidant pigment with better taste.

How much blue spirulina should I use?

Typical serving is ¼-1 teaspoon (0.5-2 grams) daily. Start small and adjust based on desired color intensity and personal tolerance. It's concentrated, so less is needed compared to regular spirulina.

Does blue spirulina taste like regular spirulina?

No—blue spirulina has a much milder taste because the strong-flavored components of spirulina are removed during extraction. It's nearly tasteless or slightly sweet, making it ideal for picky eaters or aesthetic smoothie bowls.

Is blue spirulina safe?

Generally recognized as safe when sourced from reputable suppliers. Choose third-party tested products from clean cultivation environments. Avoid if you have phenylketonuria (PKU), autoimmune conditions (consult healthcare provider), or seafood/iodine allergies.

Can I use blue spirulina for natural food coloring?

Yes! Blue spirulina is an excellent natural blue food coloring for smoothies, smoothie bowls, frostings, yogurt, baked goods, and beverages. The color is pH-sensitive—acidic ingredients (lemon, berries) may shift it toward purple/pink.
