Chlorella is a type of algae that grows in freshwater. The whole plant can be used to make nutritional supplements and medicine.
Most of the chlorella that is available in the U.S. is grown in Japan or Taiwan. It is processed and made into tablets and liquid extracts. These extracts contain "chlorella growth factor," which is described as a water-soluble extract of chlorella containing chemicals including amino acids, peptides, proteins, vitamins, sugars, and nucleic acids.
Chlorella may help to prevent low levels of iron in women who are pregnant. It is also used for depression, menstrual cramps, fibromyalgia, high cholesterol, and other conditions, but there is no good scientific evidence to support these uses.
How does it work?
Chlorella is a good source of protein, fats, carbohydrates, fiber, chlorophyll, vitamins, and minerals. It may act as an antioxidant and help to decrease cholesterol.
