3 Types Of Blue-Green Algae You Need To Know About

What’s the first thing that comes to mind when you think about the word “algae”? Is it seaweed? Maybe it’s pond scum. Well, you are technically correct as these are some of the most recognizable forms of algae in the wild. However, there is a whole other side of this group of organisms with more to offer than you could ever have imagined.

Algae is among the few groups of foods that actually deserve the title of superfood. As you will see shortly, certain species of algae cover all the bases from offering micronutrients and macronutrients to serving as great sources for rare compounds like phenylethylamine (PEA) and chlorophyll.

There are an estimated 30,000 to 1 million different species of algae in the world. However, when it comes to the superfood or even edible status, they are not all created equal. A few strains stand out for their nutritional and health benefits. These species of blue-green algae include Spirulina, Chlorella, and Aphanizomenon flos-aquae (AFA).

In the sections below, we’ll take a closer look at these three blue-green algae superstars and what they have to offer. But first, let’s explore a few common benefits of edible superfood algae. 

Rich Nutrient Profile

Certain types of algae have a good amount of macro and micronutrients including carbohydrates, fiber, minerals, vitamins, and essential amino acids. 

Contains Antioxidants

Antioxidants help your body clean up free radicals produced during everyday metabolic activities. You will notice the effects everywhere from improved cognition with better memory and concentration levels to healthier skin.

Good Source of Omega 3 and 6 Fatty Acids

Some algae are a great source of omega 3 and 6 fatty acids. These are useful in a number of functions in your body including brain development and function as well as skin and hair health.

Contains Important Phytopigments

Certain types of blue-green algae contain phytopigments which are the compounds that give them their colors. Some of the most common of these are chlorophyll, phycocyanin, and beta-carotene. These have antioxidant properties among many other perks that you have to look forward to by including blue-green algae in your diet.

The Great Trio

As mentioned, certain edible strains of algae are simply superior to others. Let’s explore what makes them so special. 


Spirulina is one of the oldest superfoods that was actively used as a food source for specific health and medicinal benefits. It can be traced back to the 16th century where the Aztecs harvested it from freshwater lakes for use as culinary ingredients.

Today, it is farmed in freshwater ponds and is used not only as a food but also as a supplement for its numerous health benefits.

Spirulina is known for its high protein content. It contains 60% protein which makes it a great addition to vegan and vegetarian diets.

Spirulina is also a great source of pigments like chlorophyll and phycocyanin as well as vitamins including vitamins A, C, D, and E. It also includes important B complex vitamins like B1, B2, B3, B5, B6, AND B9.


Chlorella was once considered a potential solution to the world hunger crisis in the mid-20th century. It was widely respected for its abundance of both micronutrients and macronutrients.

Chlorella consists of 45% protein, 20% fat, 20% carbohydrate, and 5% fiber. It’s a great source of vitamins, minerals, omega fatty acids, and free-radical fighting antioxidants. 

Aphanizomenon flos-aquae (AFA)

Aphanizomenon flos-aquae (AFA), also known as organic Wild Microalgae® is a rare strain of blue-green algae. In fact, it’s harvested in only one place in the world, Klamath Lake in Southern Oregon. Unlike these other algae superfoods, AFA is 100% wild-crafted. Meaning, it grows naturally in the lake without human intervention, is harvested non-invasively, and processed naturally for the best, unhindered benefits.

Based on its rich nutrient profile alone, AFA stands out from all other superfoods including other forms of algae.

Aphanizomenon flos-aquae (AFA), is a near-perfect superfood that contains all 20 standard amino acids, making it a complete source of protein. It also contains 13 necessary vitamins (including several B vitamins), over 60 trace minerals, essential fatty acids, antioxidant pigments phycocyanin and chlorophyll, and the mental energy activator phenylethylamine (PEA).
