Blue spirulina is a blue powder made from phycocyanin, the pigment extracted from spirulina algae. Unlike green spirulina powder, it commonly contains the blue pigment-rich portion rather than the whole dried algae.
Blue spirulina provides phycocyanin, but it has not been shown to prevent or cure a particular disease. Its clearest everyday use is adding a vivid blue color to foods and drinks, rather than delivering a proven treatment effect.
Stir Blue spirulina into smoothies, yogurt, oatmeal, or desserts. For fewer clumps, first mix the powder with a small splash of liquid to make a smooth paste, then blend or stir it into the rest of the recipe.
Blue spirulina is usually a phycocyanin-rich extract from spirulina, while green spirulina is typically the whole dried algae. They differ in color, flavor, and the range of algae components they contain.
Blue spirulina usually has a mild, fairly neutral taste, with less of the seaweed-like flavor associated with green spirulina. The flavor can still come through in a lightly flavored drink, so start with a small amount.
Blend Blue spirulina with banana and yogurt or a milk of your choice for a simple smoothie. Pale-colored ingredients show off the blue more clearly, while acidic fruits can shift the color toward purple.
Yes, high heat can fade the blue color because phycocyanin is sensitive to heat. Add Blue spirulina after a drink or dish has cooled a little, and avoid boiling it if you want to keep its bright color.
Blue spirulina can be used daily as a food ingredient when you follow the product’s serving guidance. Products vary in concentration, and there is no single established daily dose that applies to every Blue spirulina powder.
Ask your obstetrician or dietitian before using Blue spirulina during pregnancy. Product purity and ingredients vary, and whether a concentrated algae-derived product is appropriate depends on your individual health and pregnancy.
Keep Blue spirulina tightly sealed in a cool, dry place away from direct light. Moisture and sunlight can affect its color and quality, so use a dry spoon and close the package promptly after each use.

Blue spirulina is a vivid blue powder made from phycocyanin, the pigment extracted from blue-green spirulina algae. Unlike whole green spirulina, it is usually chosen for its colour and has a comparatively mild, unobtrusive taste. Stir it into smoothies, yoghurt, porridge or dessert mixtures; it is used around the world to give drinks and bowls a bright blue hue.
It is protein-rich by weight, but a typical serving is only about 3 g, so it contributes much less protein than the per-100-g figure might suggest. Pair it with banana, berries or yoghurt, and begin with a small amount if you want colour without changing the flavour much.
Very high
How many vitamins, minerals and how much fiber this food carries per calorie. A high score means a lot of nutrition for few calories.
Medium
An EatBetter score computed from fiber, protein and calorie density. A high score means staying full longer on the same calories.
Both scores are calculated per 100 g and do not change with the selected portion. The satiety score is EatBetter's own calculation, not a clinical measure.
