Chlorella (Chlorella pyrenoidosa) Chlorella is a single-cell, fresh-water green algae. Its name is derived from the fact that it contains pound for pound, the highest concentration of chlorophyll of any known plant. Chlorella contains all the B vitamins, vitamin C, E, and many minerals. It contains a “controlled growth factor,’ which taken on a regular basis, brings a noticeable increase in sustained energy and immune health. It’s been shown to be an excellent detoxifier of such heavy metals as cadmium, lead, mercury and copper. The chlorophyll in Chlorella has been shown to tighten the teeth, thus contributing to healthy gums, aids new tissue growth and prevents gums from bleeding.
