Korean researchers noted significant health benefits in 78 seniors who took a spirulina supplement. The men and women, aged 60-87 years, were randomized to get either spirulina (8 grams per day) or a placebo for 16 weeks. In men, spirulina intake was associated with a significant decrease in plasma cholesterol and a significant increase in plasma interleukin-2 (an immune system responder). In women, researchers also noted significant increases in IL-2levels and superoxide dismutase (SOD) activity, and a significant decrease intotal cholesterol. "The results demonstrate that spirulina has favourable effects on lipid profiles, immune variables, and antioxidant capacity in healthy, elderly male and female subjects," say the authors.
