A single-celled algae, chlorella is a rich source of the antioxidants vitamin C and carotenoids, B vitamins, protein, iron and chlorophyll. This "superfood" has many purported uses, including the treatment of cancer and bacterial and viral infections, enhancement of the immune system, promotion of friendly bacteria in the digestive tract, reduction of blood pressure and cholesterol, and detoxification of the blood, liver and digestive system. According to the American Cancer Society, however, there is little evidence to support these claims. If you're going to use chlorella, first discuss it with your doctor.
-
Meet with your doctor to discuss proper dosage for your needs. According to the American Cancer Society, dosage ranges from 2 grams to 15 grams per day, depending on why you are using it. Higher doses may be used for detoxification, reports the ACS. A 3-gram serving is about 1 teaspoon.
-
Mix your dosage with plain water or fruit juice. You can also add it to smoothies and green juices, suggests author and nutrition expert Jess Ainscough. If you don't like the taste of chlorella, Ainscough says it can easily be masked by adding a banana or apple to the drink. The American Cancer society reports that you can also mix chlorella powder into baked goods, such as bread or cookies.
-
Increase your dosage gradually, recommends Ainscough, especially if you are taking higher doses for detoxification purposes, as you may experience symptoms of detox. Begin with a dose of 1.5 grams for the first week, then increase it to 3 grams. Stop there or gradually increase it up to the dosage you and your doctor have decided upon.
Tip
If you're taking chlorella for detoxification purposes, Ainscough recommends drinking plenty of water -- 1 to 2 liters -- daily to aid the body in getting rid of toxins.
Warnings
The University of Maryland Medical Center reports that chlorella is high in vitamin K, a nutrient that is responsible for blood clotting. As a result, it may interfere with blood-clotting medications.
If you experience a rash or hives after taking chlorella, the American Cancer Society advises that you seek immediate medical attention.
