Chlorella pyrenoidosa | Chlorella
LATIN NAME: Chlorella pyrenoidosa
COMMON NAME: Chlorella
Species Profile
Chlorella pyrenoidosa is a single-celled green freshwater alga, each cell only a few micrometers across, that multiplies with astonishing speed in sunlit ponds. Discovered under the microscope in the nineteenth century, it became one of the first microorganisms ever farmed specifically as human food.
Its name comes from its intense chlorophyll content: chlorella is one of the greenest substances on Earth, containing more chlorophyll per gram than almost any land plant.
Science & Biotechnology
Chlorella offers around 50 to 60 percent protein by dry weight, plus chlorophyll, carotenoids, iron and a nucleotide-rich fraction known as chlorella growth factor. It has been studied for decades, including research on nutrient density and on its ability to bind certain metals in laboratory settings.
The key processing technology is cell-wall cracking: chlorella’s tough outer wall resists human digestion, so quality products are mechanically cracked or milled to make the nutrients inside accessible. Always look for broken cell wall on the label.
Uses & Benefits
Chlorella is most often taken as small pressed tablets or as powder stirred into water, juice or smoothies. Its taste is grassier and stronger than spirulina, so many newcomers start with tablets before graduating to the powder.
As with spirulina, it works best as a daily whole-food concentrate, a green nutritional foundation rather than a targeted remedy.
Cultivation
Chlorella is cultivated in open freshwater ponds or closed photobioreactors, with plenty of sunlight, carbon dioxide and mineral nutrients. The culture is harvested by centrifuge, washed, cell-wall cracked and gently dried into powder before being pressed into tablets.
Good chlorella is vivid deep green and dissolves into a bright green suspension; yellowish or brownish powder indicates oxidation or age.
Our Take
Chlorella and spirulina are the classic green pair, and they complement each other well. If we had to pick one tip, it is this: only buy broken-cell-wall chlorella, because everything else largely passes through you untouched.
