Spirulina Supplementation Boosts Immune System, Improves Anemia In People 50+

January 31, 2011: 09:29 AM EST
A supplement of microalgae-based spirulina may improve immune function and reduce anemia in people over 50, a U.S. study has found. Spirulina is a filamentous, multicellular blue-green alga that reduces inflammation and acts as an anitoxidant. The study involved 40 men and women over age 50 with no history of major chronic diseases who took a spirulina supplement daily for 12 weeks. Over the course of the study, researchers noted a steady increase in average values of mean corpuscular hemoglobin in subjects of both sexes. Older women appeared to benefit more rapidly from spirulina supplements. The majority of subjects showed increases in biomarkers indicating a stronger immune system.
