What is The Difference Between Chlorella and Spirulina?

Maybe you enjoy the health benefits of smoothies, or you are just a very healthy person. Either way, two commonly utilized superfoods are spirulina and chlorella, and it can be very confusing to know what the benefits are of these types of green algae and how they differ from one another.

Chlorella and spirulina are both types of freshwater algae that are rich in chlorophyll, loaded with nutrients and a ton of health benefits. It can be difficult to know what is the difference between chlorella and spirulina but we discuss those differences below.


What is Chlorella?

This alga has been around for approximately 2 billion years when it emerged as the first plant form that featured a clearly defined nucleus. This micro-organism is single-celled, spherically shaped and contains a nucleus. It grows in fresh water, is very small, being between eight and two microns in width, but despite its tiny size has a massive nutritional impact.

What is Spirulina?

This micro-algae is also single-celled and has a spiral shape. It naturally grows in fresh water lakes that are warm, saltwater and natural springs. It is an ancient food, dating back to the 16th century when Aztecs used it for an important food source. It is a complete food that contains protein, minerals, and plenty of vitamins.

What are the Health Benefits of Spirulina and Chlorella?

When it comes to health benefits, Spirulina and Chlorella have many. 


First, Spirulina is considered to be a nutritionally complete food and is rich with beta-carotene, containing ten times the amount of beta-carotene of a single serving of carrots.

  • This complete protein contains between 55 and 77 percent protein and every essential amino acid that the body needs.
  • Spirulina also provides fatty acids through gamma linoleum acid.
  • Spirulina contains copper, calcium, potassium, magnesium, chromium, and iron and is rich in vitamins K, C, E, B and A.

If you need any more reasons to add spirulina to your diet, it also contains phytonutrients including glycolipids, polysaccharides, sulfolipids, and chlorophyll.

Since Spirulina contains all of these nutrients, it can help the body to fight allergic reactions and infection, and it can help to lower bad cholesterol and provide protection against cancer. It can also help to increase good cholesterol and assist with weight loss.


Although Chlorella isn't as ancient as Spirulina, it has many similar nutritional benefits. This is a green alga that contains the highest level of chlorophyll of any plant known to man.

It is also a rich source of lutein, alpha-carotene, beta-carotene, and carotenoids as well as a great source of vitamins K, B, D, E and C and the minerals zinc, iron, magnesium, calcium and phosphorous.

What are the Health Benefits of Chlorella?

It is, similar to spirulina, rich in protein, containing more in a single serving that a serving of steak. It also contains the healthy fat oleic acid and supports the normal function of hormones as well as better cardiovascular health.

Chlorella can reverse the side effects of radiation and chemotherapy, lower bad cholesterol and blood pressure and remove toxins from the body.

What are the Differences Between Spirulina and Chlorella?

Although these two superfoods appear very similar, there are some distinctive differences. First of all, Chlorella is a green alga which means it has more chlorophyll than spirulina which is blue-green in color.

Chlorella contains what is known as chlorella growth factor which is a unique complex which is a result of the rapid rate at which it reproduces itself. Chlorella can quadruple itself every 24 hours, and it can repair damage sustained to nerve tissue and also aid with the production of cells.



Spirulina is more ancient than Chlorella by thousands of years and is also 100 times larger. It is richer in healthy fats as well as protein, and this is necessary for the maintenance of heart health and a sharp mind. It also contains high concentrations of cancer-preventing phytochemicals which detoxify the body, boost the immune system and fight allergy symptoms.

It has the power to detox the body from heavy metals and in particular, arsenic. Worldwide arsenic toxicity is problematic, particularly in India, Chile, Taiwan, Bangladesh, and India because people are consuming high concentrations of arsenic through their drinking water. There is no specific treatment for people who have arsenic poisoning, so alternatives such as spirulina extract are effective in decreasing arsenic levels in the body.

Spirulina can eliminate candida. Candida is part of the normal microbiota found in the gastrointestinal tract, vagina, and oral cavity and without a healthy balance of microflora, we become more susceptible to disease and sickness.

Improper digestion and leaky gut syndrome are connected directly to the imbalance of microflora and candidiasis is a leading cause of autoimmune diseases. Due to the fact that today's diet is full of sugar and ingredients that are anything but natural, our bodies are susceptible to yeast infections and Spirulina can assist.

This substance is an effective anti-microbial agent against many microbiotas including candida. Spirulina can promote the healthy growth of intestinal flora and strengthen the immune system while eliminating candida overgrowth.

Can you Take Spirulina and Chlorella Together?

Both Spirulina and Chlorella are extremely effective detoxifiers, so one must begin with a small dose and then increase it as the body responds and adjusts.

These two can be taken together, but the intense effects may be a bit disturbing at first if you take too much at once. You may experience dark green waste, a low-grade fever, restlessness, excessive gas, sleepiness or itchy skin with break outs.

These symptoms will not last forever and are evidence that your body is responding to the superfoods that you are consuming. Chlorella needs to be mechanically processed before it can be consumed because it has a cellulose wall that is not digestible. Due to the costly processing, chlorella can be more expensive than spirulina. Spirulina's cellulose wall is, on the other hand, completely and easily digestible.

Even though both Spirulina and Chlorella are superfoods, they both have different nutritional content. If you take them together, you can enjoy the benefits of both in one powerful cocktail.
