5 Spirulina Powder Substitutes

Spirulina is a type of blue-green algae that has become popular in recent years as a nutritional supplement and superfood. Known scientifically as Arthrospira platensis, spirulina is rich in protein, vitamins, minerals, and antioxidants like beta-carotene. It has a deep green color and earthy, somewhat seaweed-like taste.

Spirulina Powder Substitutes

Spirulina powder is made by drying spirulina biomass and grinding it into a fine powder. This powder can easily be added to smoothies, juices, baked goods, and other foods and beverages. However, spirulina powder can be expensive and some people find the taste unappealing.

If you're looking for alternatives to spirulina powder that offer similar nutritional benefits, there are several options to consider. Here are some of the top substitutes for spirulina powder:


Like spirulina, chlorella is a type of freshwater algae. However, chlorella is green rather than blue-green. It contains high levels of protein, iron, magnesium, amino acids, and chlorophyll. In fact, chlorella contains more chlorophyll than any other plant, which gives it antioxidant and detoxification properties.

Chlorella and spirulina have similar nutrition profiles, making chlorella an excellent substitute. Chlorella may contain slightly more fat and calories than spirulina, but it also provides more fiber, vitamin A, calcium, and phosphorous.

Chlorella has a stronger flavor than spirulina, with a bit of a grassy or earthy taste. It can be purchased as a powder and added to foods and drinks in the same way as spirulina powder.

Moringa Leaf Powder

Moringa oleifera is a tree native to India that is now grown worldwide in tropical regions. The leaves of the moringa tree are highly nutritious, sometimes referred to as a "miracle tree."

Moringa leaf powder has a similar nutrition profile to spirulina, providing protein, vitamins, minerals, and antioxidants. In particular, moringa is high in compounds like beta-carotene, vitamin C, quercetin, and chlorogenic acid that have antioxidant and anti-inflammatory effects in the body.

Some studies have found that moringa leaf powder contains higher amounts of some nutrients like iron, calcium, and vitamin C compared to spirulina. The taste is mild, resembling green tea. Moringa powder makes a great addition to smoothies, juice blends, oatmeal, and more.


Wheatgrass comes from the young shoots of the wheat plant, harvested before they mature. It can be juiced into wheatgrass juice or dried and ground into a bright green powder.

Wheatgrass is highly nutritious, providing vitamin C, vitamin A, vitamin E, calcium, magnesium, and amino acids. It also contains chlorophyll, flavonoids, and other antioxidants that may help reduce inflammation and oxidative stress.

Compared to spirulina, wheatgrass has less protein but more iron, zinc, and fiber. It has an earthy, bitter taste, so is best combined with fruit juices or sweet ingredients when using the powder.

Barley Grass Powder

Like wheatgrass, barley grass powder is made from the young leaves of the barley plant. It has a long history of use in traditional Chinese medicine.

Barley grass is rich in vitamins, minerals, and antioxidants. It provides vitamin C, iron, and fiber. It also contains chlorophyll, phenolic acids, and flavonoids that may have anti-inflammatory effects in the body.

Barley grass has a taste similar to wheatgrass but is slightly less bitter. The powder can be added to smoothies, juices, and other foods. Barley grass makes a good spirulina substitute, especially for those who want a boost of antioxidants from their supplement.

Blue-Green Algae

There are other types of blue-green algae besides spirulina that can work as substitutes. Two examples are wild blue-green algae (Aphanizomenon flos-aquae) and other Arthrospira species like Arthrospira maxima and Arthrospira platensis.

These types of algae offer very similar nutritional profiles to spirulina, containing complete protein, vitamins, minerals, and antioxidants. They come in powder or tablet form and can replace spirulina in recipes. The taste is similar but may vary slightly by species.

Considerations When Selecting a Substitute

When choosing a spirulina powder substitute, there are a few factors to keep in mind:

  • Nutritional content - Look for an option that offers a similar nutrition profile to spirulina with protein, vitamins, minerals, and antioxidants. Compare amounts of specific nutrients if looking to match spirulina closely.
  • Taste - Some substitutes like wheatgrass and chlorella have stronger flavors, so factor taste into your decision. Taste combos in your recipes.
  • Source - Opt for powders made from organic, reputable sources when possible. With supplements, quality is very important.
  • Price - Spirulina alternatives can vary in cost. Shop around to find one that fits your budget. Buying in bulk quantities can sometimes lower the price per pound.
  • Purpose - Consider why you are using spirulina and choose an alternative that will serve that purpose. For example, if you want antioxidants, moringa or wheatgrass are great choices.

No supplement will be an exact match for spirulina, but the options covered above can provide similar health benefits. Experiment to find one with nutritional value, taste, and cost that works for your needs.

How to Use Spirulina Substitute Powders

Spirulina powder substitutes can be used in much the same way as spirulina - they are simply swapped into recipes in place of spirulina powder. Here are some tips for using these powders:

  • Start with small amounts like 1 tsp per serving to test taste and texture. You can increase the amount as desired.
  • Add powders to smoothies, juice blends, protein shakes, oatmeal, yogurt, and desserts like protein balls.
  • Use substituted powders in baked goods like protein muffins, green pancakes, and bread.
  • Make facial masks, body scrubs, and other DIY beauty recipes using the powders.
  • Mix into hummus, guacamole, salad dressings, soups, and sauces for a boost of nutrients.
  • Combine with nut butter and fresh fruit to make energy bites or bars.
  • Add to popsicles, nice cream, or other chilled treats for refreshment on hot days.
  • Stir powder into homemade granola, cereal, or trail mixes.
  • Whisk into egg scrambles, frittatas, omelets, and other egg dishes.

Get creative and have fun experimenting to find the tastiest ways to use your spirulina substitute! Start with small amounts to get used to the flavor.

Key Takeaway: Spirulina powder substitutes like chlorella, moringa, wheatgrass, and blue-green algae can provide similar nutritional benefits to spirulina with protein, vitamins, minerals, and antioxidants.
