I often make spirulina smoothies for an energy boost. Whether you use blue or green spirulina, adding a teaspoon to a fruit smoothie is an easy way to increase antioxidants and nutrients while keeping the flavor pleasant.
Ingredients
- Blue spirulina powder (1 teaspoon)
- Frozen banana (½ banana)
- Frozen pineapple (1 cup)
- Frozen blueberries (⅓ cup)
- Almond milk or other plant-based milk (1 cup)

How to make the blue spirulina smoothie
Add all ingredients to a blender. Blend on high until smooth. If your blender struggles with frozen fruit, pause and stir, use a spoon to break up larger pieces, or add a splash more almond milk to help the blades catch. Once evenly blended, pour into a tall glass and serve immediately.


Serve right away for the best texture and color.


What is blue spirulina?
Blue spirulina is a powdered extract of blue-green algae made by isolating phycocyanin, the pigment that gives it a vivid blue color. It’s often used in small amounts to add antioxidants and color to smoothies, lattes, and desserts. As with any supplement, consult a healthcare professional if you have questions about adding it to your diet.

Blue vs. green spirulina
Blue spirulina is an extracted form of green spirulina that emphasizes the blue pigment phycocyanin. Green spirulina contains chlorophyll and more of the algae’s natural nutrients; it can have a stronger, more seaweed-like taste and aroma. Both varieties offer nutritional benefits and can be added to smoothies; blue spirulina is primarily chosen for its vibrant color and milder flavor.
General guidance suggests limiting spirulina to about 1 teaspoon (roughly 4 grams) per day. If you have health concerns or take medications, check with your doctor before using spirulina regularly.

Customization ideas
- Add hemp seeds, chia seeds, ground flaxseed, or a scoop of protein powder for extra nutrition.
- Swap pineapple or banana for frozen mango for a different tropical flavor.
- Stir in a handful of baby spinach or kale for added greens (this may affect the color).
Recipe tips
- Stick to about 1 teaspoon (4 grams) of spirulina daily—more won’t necessarily be better and can alter taste.
- If your blender struggles with frozen fruit, stop and stir, add a little extra liquid, or let the fruit thaw briefly before continuing.
