A Nutrient-Packed Guide: 5 BEST Substitutes for Spirulina

Have you ever heard about Spirulina, the mother of all superfoods?

This nutrient-rich blue-green algae found in various parts of the world is fast becoming a popular addition to many diets, but what happens when you can’t find Spirulina and need a substitute?

With so many different alternatives available out there, from Chlorella to Wheatgrass powder, you may be feeling bewildered on where to start.

Here’s everything you need to know about how to use these substitutes for Spirulina and the 5 best alternatives available today.

The 5 BEST Substitutes for Spirulina

Because of its high nutrient profile, spirulina is a popular supplement among athletes and health-conscious individuals.

However, some people may not be able to take spirulina due to certain allergies or dietary restrictions.

In this article, we will discuss five of the best substitutes for spirulina.

1 – Chlorella


Chlorella is a single-celled green algae that grows in fresh water.

It’s a complete protein, which means it provides all essential amino acids that cannot be produced by the body.

It’s an excellent source of B vitamins, iron and magnesium, as well as omega-3 fatty acids.

A number of studies have linked its health benefits to reduced cholesterol levels, improved gut health and general immune system support.

Unlike spirulina, which is known for its blue-green color, chlorella has a distinctly green hue.

When purchasing chlorella supplements, be sure to look for ones that have been grown in purified water to help reduce the risk of contamination from heavy metals and other pollutants found in some freshwater sources.

2 – Moringa


Moringa is an incredibly nutritious and health-supportive green superfood.

It’s slightly different from spirulina in that it grows on trees, but it still contains a high concentration of beneficial nutrients.

Like spirulina, Moringa is rich in vitamin A, iron, magnesium, and amino acids and is known to boost energy levels, immune health and overall vitality.

Additionally, Moringa also contains significant doses of calcium and Vitamin C—along with all nine essential amino acids—making it one of the most nutrient-dense foods on the planet.

It has a mild taste that works well when added to smoothies or incorporated into other dishes such as stir fries or curries.

To create its powder form, the leaves are dried at low temperatures to retain their active enzymes before being ground into a fine powder.

3 – Barley Grass Powder

Barley grass powder is another substitute for spirulina, as it is packed full of nutritional benefits and can be used in a variety of recipes.

Barley grass powder contains high concentrations of potent antioxidants, essential amino acids, essential vitamins such as B1, B2, B12 and C.

As a substitute for spirulina, barley grass powder can provide the same health benefits and can even help improve digestion.

Barley grass powder also has anti-inflammatory properties so it can help reduce inflammation throughout the body.

It can be enjoyed as a dietary supplement or added to smoothies, shakes and other recipes.

4 – Wheatgrass


Wheatgrass is a nutrient-dense grass that grows in the early stages of wheat, and it contains 70% chlorophyll – which is beneficial for cell structure.

It has high concentrations of vitamins A, C and E, as well as minerals such as iron and calcium, and it also boosts immune health.

In addition to this, wheatgrass contains protein and enzymes that can improve digestion.

When used as a spirulina substitute in recipes or smoothies, wheatgrass adds a mild flavor with notes of herbs or hay.

Its flavor is more subtle than spirulina’s deep green taste.

To use it in recipes such as smoothies, juices or dressings they can be blended together with other ingredients until completely dissolved.

Alternatively you can buy wheatgrass powder which blends much faster into liquids.

Like spirulina, wheatgrass should be stored correctly – away from light or heat sources – but unlike spirulina it won’t last quite so long after opening when refrigerated; its shelf life is around one month if sealed properly in an airtight container kept in dry conditions away from direct sunlight or heat sources.

5 – Hemp Seeds

Hemp seeds are one of the best substitutes for spirulina since they are high in protein and other nutrients.

These small seeds offer a pleasant nutty flavor and are rich in omega-3 and omega-6 fatty acids.

Hemp seeds can be used as a topping on salads, soups, and yogurts, or added to smoothies.

Clinical studies have also indicated that they may have beneficial benefits in reducing bad cholesterol levels as well as improving symptoms of certain skin conditions.

A quarter cup of hemp seeds contains 11 grams of plant-based protein and 9 grams of fiber.

In addition, hemp seeds are high in magnesium, potassium, iron, zinc, B-vitamins, and vitamins E and K.
