Chlorella is a type of single-cell green algae. Within chlorella are high levels of chlorophyll, protein, iron, vitamins C and B₁₂, beta carotene, and 19 amino acids.

Several studies show that chlorella may be effective in treating some types of cancer, high cholesterol, hypertension (high blood pressure) and fibromyalgia syndrome. It is also an immune system enhancer and it can aid the body in detoxifying itself.

Several scientific studies have shown chlorella's ability to combat cancer cells. The method in which it does so however, still remains a mystery. One theory among experts is that chlorella stimulates the activity of T-cells, which play a key role in antibody immunity as well as large cells called macrophages which shield the body from infection by removing waste products, harmful microorganisms, and other toxins from the bloodstream. Interferon is a protein produced by the body that performs antiviral and antitumor activities. When T-cell and macrophage production is increased, interferon levels in the body are also increased. This process enhances the immune system's ability to combat harmful substances like viruses and bacteria.

Studies in laboratory animals suggest some substances in chlorella may reduce bone marrow suppression in patients taking the anticancer drug fluorouracil. As a result, white blood cell and platelet counts are increased which reduces the risk of infection and bleeding.

Other studies have shown chlorella to reduce cholesterol levels significantly in laboratory animals. Studies are currently taking place to see if the same is true in humans.

A study reported in the March 2003 issue of Original Internist showed that treatment with 10 grams of chlorella every day daily for three months significantly improved blood pressure in 25% of the patients involved in the study.

A study in the year 2000 showed chlorella to be beneficial in treating patients with fibromyalgia after just two months of taking it.

You can find chlorella in a number of different forms including capsule, softgel, powder, tablet and liquid. It is available by itself or combined with other green food extracts such as wheat grass, barley grass, and spirulina which are all great as well.

Since chlorella products can vary considerably, be sure to do your due diligence first prior to purchasing a chlorella supplement.

* Important note: The recommended doses are for those over age 18. Always check herb and vitamin use with your child’s health care practitioner prior to administering them.
