Blue spirulina powder provides phycocyanin, the pigment responsible for its vivid color, and some products also contain protein. Phycocyanin has antioxidant activity in research, but blue spirulina powder has not been shown to prevent or treat disease.
Yes, you can stir blue spirulina powder into coffee, but the drink may turn an unusual color and heat can dull the blue pigment. For a brighter result, let the coffee cool a little before mixing it in.
Usually not as strongly: blue spirulina powder tends to taste milder than whole green spirulina, which often has an earthy, seaweed-like flavor. Taste varies by product, and adding it to fruit, yogurt, or a smoothie can mask it.
Yes, blue spirulina powder can be mixed into batters and frostings, but baking heat may fade its blue color. For a more vivid finish, add it to an unheated topping or stir it into a recipe after cooking.
Not exactly. Blue spirulina powder is generally made from the blue phycocyanin pigment extracted from spirulina, a type of blue-green algae; it is not necessarily the same as whole dried spirulina or other algae powders.
Blue spirulina powder can temporarily tint the tongue or the surface of foods because its pigment is strong. The color generally washes away with water or brushing, but mixing the powder carefully can help avoid splashes and stains on clothing.
To prevent clumps, first blend blue spirulina powder with a small splash of liquid to make a smooth paste, then add the rest. A small whisk or blender works better than sprinkling the powder into a full glass at once.
No, blue spirulina powder is not a natural source of caffeine. If you add it to coffee, tea, or an energy drink, any caffeine comes from that beverage rather than from the spirulina powder.
Blue spirulina powder keeps best when tightly sealed and stored in a cool, dry, dark place. Follow the package date and instructions, and discard it if moisture gets inside or you notice an unusual smell, texture, or appearance.
There is not enough reliable evidence to establish that every blue spirulina powder product is safe during pregnancy. Product purity can vary, so ask your prenatal clinician before using it regularly, especially if the source or testing information is unclear.

Blue spirulina powder is made from spirulina algae and gets its vivid blue colour from the pigment phycocyanin. It is not a traditional staple, but is used in smoothies, yoghurt, drinks and smoothie bowls for colour, with a subtle algae-derived flavour.
Its taste is usually mild, earthy and slightly sea-like; berries, banana and citrus can balance it in a drink or bowl. Stir a little into cold liquids or yoghurt, since it can clump if added all at once. The powder contains 58 g of protein per 100 g, but a typical teaspoon is only about 3 g, so a usual serving contributes relatively little protein. Start with a small amount and adjust to taste, especially if you prefer a less pronounced earthy note.
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.
