TraditionWARNING: DISCLAIMER: The below uses are based on tradition, scientific theories, or limited research. They often have not been thoroughly tested in humans, and safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider. There may be other proposed uses that are not listed below.

Adults (18 years and older)
Spirulina has typically been taken by mouth two to three times daily with meals in doses of 1-1.4 grams for diabetes mellitus (type 2), high cholesterol, or oral leukoplakia (pre-cancerous mouth lesions). For weight loss, 200 milligrams of spirulina tablets by mouth three times daily, taken just before eating, has been studied. Two grams of spirulina has been used for nasal allergies. For arsenic poisoning, twice daily doses of 250 milligrams of spirulina extract plus 2 milligrams of zinc may be helpful.
Children (under 18 years old)
Not enough scientific information is available to advise the safe use of spirulina in children.
SafetyDISCLAIMER: Many complementary techniques are practiced by healthcare professionals with formal training, in accordance with the standards of national organizations. However, this is not universally the case, and adverse effects are possible. Due to limited research, in some cases only limited safety information is available.
Avoid use in individuals with known allergy to spirulina, blue-green algae species, or any of their constituents.
Side Effects and Warnings
Few side effects have been reported with spirulina use. The most frequently reported adverse effects are headache, muscle pain, flushing of the face, sweating, and difficulty concentrating. These have been described in people taking 1 gram of spirulina by mouth daily. Skin reactions have also been reported.
Blue-green algae, especially types that are usually harvested in uncontrolled settings (Anabaena spp., Aphanizomenon spp., and Microcystis spp.), may be contaminated with heavy metals. Liver damage, diarrhea, and vomiting have been reported.
Pregnancy and Breastfeeding
There is not enough information to recommend the safe use of spirulina during pregnancy or breastfeeding. In mice, diets containing up to 30% spirulina are not reported to cause harmful effects to either the mother or the offspring. However, reliable human studies addressing safety during pregnancy or breastfeeding are not available.
