What exactly are Chlorella and Spirulina?

Chlorella and Spirulina are considered to be two of the most nutrient-dense algae available.

Chlorella is a bright green, aquatic plant known as an algae that has been known to exist for 2 billion years, but it was discovered much later, in 1890, by Dutch microbiologist Dr. Beijerinck. It grows in lake structures in areas such as Japan and Taiwan, where it feeds on the natural light to generate a pool of nutrients. The tough cell walls are cracked by most producers to soften its structure and make it easier for us to consume the enclosed nutrients, which come in a powdered form and pack the body with energy.

Spirulina, which is a blue-green algae, has been used by the Aztecs for many centuries. It is found that it has the versatility to grow in both freshwater and saltwater. Despite the bitter taste, Spirulina delivers on the promise of protein and essential nutrients that are beneficial for anyone on a plant-based diet. It is commonly dried to retain its nutritional value and can be found in powders and capsules.

Chlorella and Spirulina are two such products that are known to have numerous health benefits vested in them. They are known to enhance immunity, may support detoxification, and give omega-3 fatty acids and complete proteins. Apart from that, they contain antioxidants, which tackle oxidative stress.

They can be added to the super greens powder smoothie recipes, used for garnishing energy bars, or taken in the form of tablets. In whichever manner you decide to consume Chlorella and Spirulina food products, they are valuable additions to your wellness lifestyle.
