Who would have thought the green slime on stagnant water ponds would make for health supplements? But the spiral-shaped microscopic blue-green algae (Arthrospira) packed with 70 per cent protein, vitamins and phytochemicals has been bottled as remedy for everything from weight-loss to diabetes in the form of spirulina. So what makes spirulina a superfood?Powerful antioxidant
Spirulina contains antioxidant vitamins C and E, beta carotene, and minerals selenium, manganese, zinc, copper, iron and chromium. Its antioxidant capabilities reduce the toxic effects of cadmium and of free radicals generated by inflammatory processes.
Combats cancer
Animal studies have shown that spirulina produces tumor regression. In one human trial, where the effects of spirulina on oral carcinogenesis were studied, researchers found that 45 per cent of their subjects showed complete regression of leukoplakia, after taking spirulina supplements for one year.
Lowers cholesterol
Studies in Japan and India showed that several grams of spirulina daily can reduce serum LDL (bad cholesterol) and raise HDL (good cholesterol). In a 2007 study, 36 human subjects ingested 4.5 grams of spirulina daily for six weeks without making any other modifications in their diets or lifestyles. After the six week period, total cholesterol concentrations and levels of body fat were lowered. Systolic and diastolic blood pressure was reduced.
Fights off fatigue
Spirulina restores the body to a state of high energy probably because of its high levels of polysaccharides and essential fatty acids. It is one of the few sources of gamma linolenic acid (GLA), providing 30 mg per serving. Spirulina may also boost energy through the lactobacilli in the intestinal tract, which aid in the release of nutrients from food, and enabling energy production for promoting Vitamin B6.
People with a metabolic condition called phenylketonuria (PKU), who can’t metabolise phenylalanine amino acid, should avoid taking spirulina which is rich in all amino acids, including phenylalanine. If you have an autoimmune disease, e.g. multiple sclerosis, rheumatoid arthritis, or lupus, you should avoid spirulina as it could stimulate your immune system, making your condition worse.
Consult a health care provider before taking the supplement.
