What is Blue Spirulina?

Blue spirulina is a natural blue pigment extracted from Arthrospira platensis, a species of blue-green microalgae. Unlike traditional green spirulina, which contains green chlorophyll alongside blue pigments, blue spirulina consists almost entirely of phycocyanin. This specialized extraction gives it a striking, vivid cobalt blue color while eliminating the distinct earthy, fishy taste and strong odor commonly associated with raw green algae.

Nutritonally, blue spirulina is prized for its high concentration of phycocyanin, a potent antioxidant that supports immune health and helps fight cellular oxidative stress. It also provides key B vitamins, essential trace minerals, and plant nutrients. Food creators, smoothie shops, and home cooks frequently use blue spirulina powder as a natural food coloring. It mixes easily into smoothie bowls, chia puddings, plant milks, lattes, and baked treats without requiring synthetic dyes, making it a functional ingredient for vibrant, nutrient-dense foods.
