Fans of blue-green algae call it a "super food" because it is rich in protein, calcium, iron, chlorophyll, vitamins and other nutrients. Blue-green algae products, such as spirulina, can be purchased in a fresh dried form, and in tablets, capsules, extract, flakes and powder. Blue-green algae also can be grown at home.
Immune System Booster
Phycocyanin, the blue pigment in this algae, is a powerful antioxidant for free radical scavenging, according to a 2004 review of studies in "Life Sciences" journal (see link in Resources). This makes blue-green algae a great immune system booster.
A study in a Biochemical and Biophysical Research Communications issue from 2000 (also cited in the "Life Sciences" review)also noted that phycocyanin inhibits the growth of certain cancer cells.
Additionally, free radicals are indicated to be partially responsible for negative effects of aging, according to the Mayo Clinic (see link in Resources). The action of blue-green algae against free radicals is of benefit here also.
Phycocyanin reduces inflammation, according to a study published in a 2007 issue of "Life Sciences." Other anti-inflammatory substances in blue-green algae include beta carotene, lycopene and lutein.
Blue-green algae are a concentrated source of chlorophyll, the green pigment, which is recognized for its regenerating and immune-enhancing properties.
