Spirulina Boosts Immunity
and Clears Bacterial Infections
The 44th Western Poultry Disease Conference
Sacramento, CA, March 5, 1995
Scientists announced the natural food spirulina dramatically strengthens
the immune system. Immunologist and Professor M.A. Qureshi, PhD, released
a study sponsored by Earthrise Company of California. "Immunomodulary
Effects of Spirulina Supplementation in Chickens"1,2 shows
small daily doses of spirulina in a poultry diet (less than 1%) greatly
improve T-cell and thymus function. Spirulina especially boosts cells
called macrophages, the first line of body defense. These cells communicate
with T-cells to coordinate the fight against infections.
Spirulina caused the cells to increase in number, be more active and
display more effective microbial killing. The whole immune system array
of killer cells, helper cells and antibody production is supercharged.
This means spirulina fed birds are much more resistant to infection,
with no undesirable side effects.
Researchers are testing the theory that spirulina acts like a broad
spectrum vaccine against bacteria. It may also protect against other
disease causing microbes and cancer. Because it is a safe natural food,
it has created a sensation among animal scientists. They are scrambling
to replace ineffective antibiotics with probiotics like spirulina that
strengthen immune systems and prevent disease.
Scientists in China and Japan independently reported spirulina and its
extracts fed to mice increase macrophage function, antibody production
and infection-fighting T-cells. 3,4,5 One study found spirulina
extracts inhibited cancer by boosting the immune system.6 The
active phytonutrients are a polysaccharide (a complex sugar molecule)
unique to spirulina and phycocyanin (the blue pigment found only in blue-green
algae). In 1979, Russian scientists published initial research on the
immune stimulating effects on rabbits from lipopolysaccharides in spirulina.7
These discoveries are significant for human health. Overused antibiotics
have created highly resistant bacteria. Most antibiotics are no longer
effective. Now scientists want to identify probiotics that strengthen
the immune system to prevent disease and cancer. Based on this animal
research, as little as 3 grams per day of spirulina may be effective
for humans. It seems to turbocharge the immune system to seek out and
destroy disease causing microorganisms and cancer cells.
Spirulina, blue-green algae, is 60% all-vegetable protein, easy-to-digest,
with the highest food concentration of the antioxidant beta carotene,
iron, vitamin B-12, and the rare gamma-linolenic acid (GLA). Its dark
green color comes from the combination of the phytonutrients carotene,
chlorophyll and phycocyanin. It is also a source of polysaccharides and
sulfoglycolipids. In the past 15 years, this nutritious microscopic aquatic
plant has gained worldwide acceptance.
Spirulina is a safe whole food consumed by traditional people for centuries.
It has been enjoyed by millions of people as a natural food in the USA,
Japan and Europe. Earthrise Farms, the world's largest spirulina farm
located in the sunny California desert, produces over 300 tons per year.
The immune enhancement study with chickens used spirulina ecologically
grown at Earthrise Farms free of pesticides.
