Few foods have a legacy as fascinating as spirulina. This ancient blue-green algae has nourished Aztec warriors, fueled space missions for NASA, and earned its place as one of the most nutrient-packed foods on Earth. 

Spirulina has a pretty impressive nutrient profile. Per gram, it’s one of the richest sources of plant-based protein, containing all nine essential amino acids. It’s also packed with vitamins (like B1, B2, and B3), iron, magnesium, potassium, beta-carotene,and antioxidants such as phycocyanin, which gives spirulina its vibrant blue-green colour. For anyone looking to boost their intake of essential nutrients—especially vegetarians, vegans, or those with restrictive diets—spirulina is a valuable option.

What is spirulina:

It's a type of blue green algae, a cynobacteria, that grows naturally in both fresh and saltwater environments. 

With China being the largest producer of spirulina globally. Our spirulina is pretty special though, it's grown right here in Australia, using pure clean water. Grown in a controlled environment to prevent contamination from heavy metals, bacteria, or toxins (such as microcystins).

Spirulina in Space

Spirulina gained global recognition when NASA included it in astronaut diets during space missions. Its nutrient density along with its compact size and long shelf life, made it a perfect food for space travel. 

And this is why….

Nutrient-Dense: High in protein (60-70%), all essential amino acids, vitamins (B1, B2, B3), iron, magnesium, and antioxidants like phycocyanin.

Complete Plant-Based Protein: An excellent protein source for vegans and vegetarians.

Rich in Antioxidants: Phycocyanin and beta-carotene combat oxidative stress.

Boosts Energy Levels: High levels of B vitamins and iron help reduce fatigue and support energy metabolism.

Improves Gut Health: Promotes the growth of beneficial gut bacteria.

Good for Skin and Hair: Rich in antioxidants and vitamins that promote healthy skin and hair.

If you were to ask me what is one superfood that everyone- adults and children, should have - its spirulina. The United Nations agrees,  recognising spirulina as a "food of the future." for its potential to combat malnutrition and food insecurity.  Do yourself a favour and add spirulina to your life.
