You’ve probably seen a scoop of intensely green powder added to a smoothie and wondered: What exactly is spirulina?
Spirulina is commonly called a blue-green algae, although technically it is a type of cyanobacteria. Once dried and ground, it becomes the distinctive dark green powder you'll find in smoothies, smoothie bowls and all kinds of creative recipes.
It also has a flavor all its own.
If you've been curious about spirulina powder, here's what to know before you try it.
What Is Spirulina Powder?
Spirulina is the common name for types of cyanobacteria commonly referred to as blue-green algae.
After spirulina is harvested and dried, it can be ground into the fine green powder commonly sold for culinary use.
Our organic spirulina powder at Life Essentials Refillery is Spirulina platensis. It is organic, kosher certified and non-irradiated.
What Does Spirulina Powder Taste Like?
We're not going to tell you it tastes like nothing.
Spirulina has a strong, grassy, earthy flavor with noticeable marine notes.
That's one reason it's commonly mixed with other flavorful ingredients instead of eaten by itself.
If you're trying spirulina for the first time, start with a small amount. You can always add more after you know how much of the flavor you enjoy.
How Do You Use Spirulina Powder?
Smoothies may be the most familiar use for spirulina, but they're definitely not the only option.
You can experiment with spirulina powder in smoothies, smoothie bowls, hummus, dips, green sauces, dressings, seasoning blends, energy bites and even baked goods.
Its dramatic green color also makes it a fun ingredient when you want to experiment in the kitchen.
How Do You Use Spirulina Powder in a Smoothie?
This is probably the easiest place to start.
Add a small amount of spirulina powder to your usual smoothie and blend it with the other ingredients.
Because spirulina has a noticeable earthy flavor, pairing it with flavorful fruits and other ingredients can make it more approachable for someone trying it for the first time.
There's no reason to dump a huge scoop into your first smoothie. Start small and see what you actually like.
Can You Cook With Spirulina?
Spirulina isn't limited to drinks.
Try experimenting with small amounts in hummus, sauces, dips, seasoning blends and baked goods.
Just remember that both the flavor and color can be noticeable, so a little experimentation goes a long way.
Is Spirulina Naturally Green?
Yes—and its color is one of the things that makes spirulina so recognizable.
Spirulina contains naturally occurring pigments, including chlorophyll and phycocyanin. Phycocyanin contributes to the characteristic blue-green appearance associated with spirulina.
So that striking color isn't there just to make your smoothie look interesting.
Is Spirulina the Same as Chlorella?
No. Although you'll often see spirulina and chlorella sold alongside one another, they aren't the same thing.
Both are green ingredients used in powders and food products, but they are biologically different.
If a recipe specifically calls for spirulina, don't assume every other green powder will behave or taste exactly the same.
Is Spirulina Powder Gluten-Free?
Spirulina itself does not naturally contain gluten.
However, someone who needs to strictly avoid gluten for celiac disease or another medical reason should always consider how a particular product has been processed and handled and whether cross-contact is possible.
Is Organic Spirulina Different?
If buying organic ingredients is important to you, look specifically for a product identified as organic spirulina powder.
The spirulina we carry at Life Essentials Refillery is organic, kosher certified and non-irradiated.
It's also sold by the ounce, which is particularly handy if you've never tried spirulina before.

The Bottom Line
Spirulina is one of those ingredients that can look a little intimidating the first time you encounter it.
It's intensely green. It has a distinct flavor. And you might have absolutely no idea what you're supposed to do with it.
But that's also what makes exploring new bulk ingredients fun.
Start with a little. Toss some into a smoothie. Experiment with a sauce or hummus. Find out whether it's something you enjoy before buying a giant container.
That's exactly what shopping by the ounce is for.
