Chlorella / Chlorella pyrenoidosa
A unicellular green alga belonging to the genus Chlorella, it is grown via photosynthesis in open freshwater habitats. It’s a close cousin to the saltwater-sourced Spirulina. There are more than a hundred Chlorella species and known for its nutrient rich properties and as a plant-derived source of iron.

Marine Algae
Algae are almost ubiquitous, between microscopic and macroscopic species, and can be found in either fresh water or in oceans. Marine macroalgae, commonly known as seaweed, are plant-like organisms that can be seen by the naked eye and come in many varieties ranging from a few millimetres or centimetres in size, while the largest grow to a length of 30 to 50 meters.[1]
Botanically, macroalgae are classified as green, brown, or red and is estimated to be at least 30,000 known species of macroalgae found in the marine environment.[2]
Given that all the substances that seaweeds need in order to survive are dissolved in the water, macroalgae, unlike plants, have no need of roots, stems, or real leaves. Nutrients and gases are exchanged directly across the surface of the seaweed by diffusion and active transport.
Marine algae draw from the sea a wealth of mineral elements, and also known as a source of vitamins.
More information
Marine algae is used as a natural source of vitamin D to:
- Support healthy immune system and muscle function
- Support bone strength and bone mineralisation
- Support calcium absorption. A diet deficient in calcium can lead to osteoporosis in later life.
- Support muscle function
Traditionally
For several centuries there has been a traditional use of seaweeds as food in China, Japan and the Republic of Korea.

Spirulina / Arthrospira platensis
Is a type of microscopic bacteria called cyanobacterium grown in both fresh and salt water and is often referred to as blue-green algae. The name originates from the Latin word for ‘helix’, or ‘spiral’, referring to the spiral nature of its filaments. Coined a green superfood, it is packed with a high concentration of vitamins, minerals and antioxidants.

With a history of human consumption dating back to the Aztec period, Spirulina is one of the oldest life forms on Earth. In fact, this simple life – form is partly responsible for the Great Oxidation Event, where scientists believe it was producing oxygen in the planet’s atmosphere billions of years ago, which triggered the evolution of complex life. Its oxygen production allowed the planet’s originating life forms to begin and develop.
