Is Spirulina Good For the Immune System?

Western medical science has now begun to examine possible health benefits of using spirulina to address certain medical concerns. One of the largest areas of investigation is how spirulina affects the immune system. Some experts are researching whether the nutrients found in spirulina can boost the body's natural defenses, which could make it more capable of fighting off illnesses and disease. A very small study at the Division of Rheumatology, Allergy and Clinical Immunology at the University of California at Davis found that elderly patients who took spirulina for 12 weeks experienced an increase in white blood cells, which are essential to the functioning of the immune system.

Is Spirulina Safe?

While many people can safely take spirulina, this supplement may not be right for everyone. Spirulina supplements may interact with other medications or herbal supplements.
