The Worlds Healthiest Foods : Chlorella

Updated on April 23, 2011

Chlorella is a single cell micro-algae containing green photosynthetic pigments chlorophyll -a and –b in its chloroplast, also giving chlorella its emerald-green pigment color and seaweed-like smell. Through the process of photosynthesis it can multiply at a rapid rate while only requiring a minimum of carbon dioxide, water, sunlight and a small amount of minerals to reproduce. It dates back 500 million years and was the first simplest form of life with a true nucleus.

Now let’s move on to why this single cell algae is so fascinating…

Chlorella is an algae with a very dense amount of nutritional elements: vitamins, macro minerals, trace minerals, essential fatty acids, protein, nucleic acids (RNA and DNA), very high amounts of chlorophyll, and other phytochemicals. Chlorella is considered one of the most complete foods and you could probably live off it. Depending on the brand of chlorella, digestible rate can be anywhere from 85% to 95%.


There are 20 essential amino acids required by the body and are the building blocks for protein and muscle tissue. Amino acids help all kinds of physiological processes including recover, muscle and strength gains and fat loss as well as mood and brain function. Chlorella contains roughly 60% to 70% protein and per ounce contains 3 three more protein than beef.

Chlorella provides 19 of the 22 amino acids, including the 8 essential ones, making it a complete protein.


The nutrients present in chlorella are:

  • All known B vitamins including B12.
  • Vitamin C
  • Vitamin E
  • Macro minerals: iron, magnesium, zinc, calcium, potassium and many more.
  • Trace Minerals
  • Omega-3 fatty acids including GLA
  • Mucopolysaccharides
  • Beta-Carotene
  • Nucleic acids (RNA and DNA)
  • Chlorophyll

Chlorella may help, prevent and even reverse

  • Cancer
  • Obesity
  • Diabetes
  • Hypoglycemia
  • Depression
  • Arthritis
  • Liver disorders
  • Intestinal ulcers
  • Hemorrhoids
  • Asthma
  • High blood pressure
  • Constipation
  • Bleeding gums
  • Infections
  • Inflammation of joints and tissues
  • Body odor / breath odor
  • Fatty acid, mineral and vitamin deficiencies

When taking chlorella don’t expect all or any of these to take place. Each person is different and each person will have a different experience.

When I take chlorella, for example, I definitely notice the difference with my bowel movements and digestion.

Chlorella Growth Factor (CGF)

A growth factor in health and nutrition simply refers to a substance that builds the immune system. Chlorella has the ability, through photosynthesis, to quadruple every 20 hours, and it’s because of this process that the Chlorella Growth Factor is produced. CGF comprises roughly 3% of the chlorella cell but remains 100% water soluble which makes it easily accessible by the body.

Chlorella Growth Factor is a “nucleotide-peptide complex” of substances found only in chlorella, thus the CGF. It has been proven to cause children and young animals to grow at an accelerate rate increase the healing rate of damaged tissue.


Chlorella contains the largest amount of chlorophyll per gram than any other plant. Chlorophyll is what gives plants their green color but also shares a similar molecular structure as the hemoglobin of the human blood.

Chlorophyll helps our bodies detox themselves, fight infection, help heal wounds and promote the health of our circulatory, digestive, and immune systems. It also increases the number of red blood cells and therefore increases oxygen utilization by the body.


Chlorella is an excellent way to detox oneself. It has been shown to remove heavy metals such as mercury, lead, pesticides, such as PCB’s; and dioxins that are accumulate in our bodies.

The detoxification of heavy metals and other chemicals in the blood can take several months depending on how much chlorella is being taken. Gradual increases of chlorella are recommended and up to 5-7 grams seem to be a healthy range.

Chlorella is comprised of a fibrous, indigestible outer shell and its inner nutrients. This fibrous material has been proven to bind with heavy metals and pesticides and excrete them.

What you need to know

Which brand of chlorella

Choosing the right brand of chlorella is crucial to getting as much from this algae as possible. Make sure you check the labels and always check to see if the “cell wall” has been broken. However, this still isn’t enough; depending on the method that the cell wall has been broken and the environment and culture method the chlorella has been grown in, results can vary significantly.

My suggestion is to choose a brand/product that is as organic and pure as possible and experiment. Try different products and see which one yields the best results. Check reviews as well for consistency.

Best store to buy chlorella

You can find chlorella at just about any health food store but I suggest online buying.

The two top rated vitamin online stores are :

Swanson Vitamins.

Chlorella roughly sells for about 12 cents per gram.


Chlorella roughly sells for about 12.5 cents per gram.
