Anemia is a disease in which one has a low number of red blood cells to carry oxygen to the body. This can cause extreme fatigue and weakness.
Anemia is caused by a lack of iron in the diet. Spirulina helps with iron deficiency because it contains a large percentage of iron compared to most other foods.
Several independent research studies have shown that spirulina has a positive effect on anemia. Spirulina can increase the hemoglobin in red blood cells to improve the immune function and bring oxygen to tissues in the body. On average most people need to take spirulina for 6-12 weeks to help improve their anemia symptoms (1).
