Chlorella is a type of freshwater algae commonly sourced in and near Japan. Chlorella is often associated with another algae similar in appearance known as spirulina. Although similar to spirulina, chlorella is a single-cell organism, while spirulina is multi-cell. Unlike spirulina, the outer cell wall of chlorella is hard; unable to be processed by the human digestive tract, therefore, chlorella must be consumed in supplement form after undergoing a special process to "crack" the cell walls. Chlorella is a popular supplement worldwide, but is the most popular supplement sold in Japan!
Chlorella is believed to be the oldest species of algae on the planet, present for three billion years, and reproduces quickly, making it a highly sustainable nutrient source. Chlorella is tiny, unable to be seen without a microscope and as such, as not discovered until 1890 by the Dutch microbiologist, Dr. Beijerinck. It was well-documented that chlorella was nutrient-dense, even in previous decades. During the first world war, chlorella was cultivated in mass amounts to serve as a protein source. In modern-day. NASA studied chlorella as potential space food, due to the high amounts of nutrients even in tiny quantities.
Chlorella is also known as; Algue Verte d’Eau Douce, Bulgarian Chlorella, Bulgarian Green Algae, Chinese Chlorella, Chlorella Algae, Chlorella pyrenoidosa, Chlorella vulgaris, Chlorelle, Clorela, Freshwater Green Algae, Freshwater Seaweed, Green Alga, Green Algae, Japanese Chlorella, Seaweed, Yaeyama Chlorella.
