The human immunodeficiency virus, or HIV, attacks white blood cells known as CD4 cells, making an infected individual more susceptible to potentially life-threatening conditions like cancer and pneumonia. There is no cure for HIV, but antiretroviral drugs help to improve quality of life and prevent the virus from replicating. Spirulina is sometimes used as a complementary treatment for HIV, although there is little evidence that it treats the condition itself. Do not use spirulina in place of HIV medicines and get medical advice before using it.
Properties and Potential Benefits
Spirulina, also known as blue-green algae, found in tropical, subtropical waters and fresh water lakes, might play a role in a number of ailments including diabetes, hay fever, depression, cancer and anxiety. The Memorial Sloan-Kettering Cancer Center notes that it is also used to help prevent viral infections and might play a role in the treatment of HIV and AIDS. It contains an abundance of biological compounds including minerals and vitamins and proteins although its mechanism of action is not understood.
Administration
Spirulina is available in capsules from many health foods stores. Since it is not a proven treatment for HIV, guidance regarding a suitable dose is lacking. In addition, MedlinePlus states an appropriate dose may depend on the patient's age and health. However, your doctor may be able to advise you on a suitable dose.
Effectiveness
Clinical trials evaluating the effects of spirulina on HIV are lacking. However, an article published in "Medical Hypotheses" in 2004 notes that regular consumption of spirulina might help prevent HIV infection and suppress the viral load in individuals already infected with HIV. The results of a study published in the November 2005 issue of the "Annals of Nutrition & Metabolism" indicates that spirulina might also help alleviate anemia and aid weight gain in under-nourished HIV-infected children..
Safety Considerations
Spirulina might cause side effects including nausea, vomiting and insomnia, although these effects are rare. The Memorial Sloan-Kettering Cancer Center warns that some spirulina supplements may be contaminated with microcystin, algae that be have toxic effects on the liver and kidneys. To ensure you choose a high quality supplement ask your pharmacist to guide you. Don't take spirulina if you are pregnant or breastfeeding and avoid using it alongside immunosuppressant drugs.
