Spirulina may reduce oxidative stress

Oxidative stress is intimately associated with many diseases, including chronic obstructive pulmonary disease (COPD). In a study with patients with chronic obstructive pulmonary disease, spirulina intake for 30 and 60 days at (500 × 2) mg dose significantly reduced blood levels of oxidative stress markers as well as cholesterol, while increasing glutathione and Vit C levels (both cellular antioxidants), and the activity of certain enzymes and genes. At the same time, spirulina intake for 30 and 60 days at (500 × 4) mg dose had a significant favourable effect on all targeted blood parameters except for HDL. Antioxidant status and lipid profile of chronic obstructive pulmonary disease patients are proven to be improved through an interventional 2 months course of spirulina. Oxidative stress is shown to be reduced as a result of spirulina intervention.
