What it is

Chlorella, a type of green, freshwater algae, is packed with protein, B vitamins, antioxidants (including vitamin C and carotenoids), and chlorophyll.


Chlorella has a fibrous outer shell that detoxifies the bloodstream by binding to pesticides and heavy metals, eliminating them from the body. Some research suggests that chlorella may be effective in reducing chemotherapy side effects such as fatigue. Chlorella may also improve digestion.

How to take it*

Chlorella is available in tablet, powder, and liquid extract form. The average recommended dose is 2–3 grams per day, although some experts suggest more for detoxification. Powdered chlorella has a mild green tea flavor and can be added to soup, baked goods, smoothies, stir fries, and tea; 1 rounded teaspoon equals 5 grams.

Side effects

Some people may experience gas, cramping, constipation, or diarrhea when they begin taking chlorella, so it’s a good idea to supplement gradually. Chlorella use has also been associated with increased uric acid in the bloodstream, which is linked to gout and kidney stones.
