Chlorella Chlorella


Benefits of Nature's Best Detoxifier

History of Chlorella

Chlorella is quickly becoming well known (along with spirulina) as one of the world’s healthiest foods. With so many reasons to take it, including detox, immune support, and better athletic performance, chlorella will soon be in green smoothies across the country! While the issues concerning our agriculture and environment seem to be growing more alarming, there is one simple way to help your body in its battle with toxins – chlorella algae.

Studied for Decades (But Still Unknown!)

Chlorella has been around for hundreds of millions of years. However, awareness of its nutritional properties started less than 100 years ago. Following World War 2, there was a global food shortage. As the population of the world continued to rise exponentially, economists feared that global food production could not meet the demands of the growing population. Food scientists, hard at work searching for sustainable means of nutrition, came across chlorella.

Could Chlorella Catch On?

Chlorella’s cheer section in the 1950s was huge, including highly reputable organizations such as:

  • The Carnegie Institution
  • The Rockefeller Foundation
  • The National Institutes of Health
  • The Atomic Energy Commission
  • The Food and Agriculture Organization (FAO)
  • The American Chemical Society
  • The American Association for the Advancement of Science (AAAS)
  • Scientific American
  • Scientific Monthly
  • Science
  • Stanford University
  • The University of California at Berkeley
  • The Massachusetts Institute of Technology
  • Harvard University
  • The University of Wisconsin

All of these organizations saw the potential of chlorella as a sustainable food source. There were just two problems. The first was that the technology to grow chlorella on a large enough scale did not exist (yet). While that problem could have been surpassed there was a much larger issue for chlorella as a mainstream food product – it didn’t taste like ice cream.

Nutritious, But Not Nutella

Researchers were concerned that chlorella’s lack of conventional flavor would prevent it from catching on as a source of nutrition. So, while chlorella had all of the nutritional properties researchers looked for, it was ultimately sidelined for lack of mainstream appeal. [1]

NASA and Chlorella's Comeback

Fortunately, not everyone was looking to bring chlorella into the mainstream. As concerns over food shortages died down in the 1960s, NASA began studying chlorella as a means of sustainable food and oxygen production in space. This research was very promising and continues even in recent years.

Despite the promising research that’s shown how incredible chlorella is as a source of nutrition, it remains relatively unknown due to its lack of mainstream flavor. However, the algae food market has been making a slow and steady comeback. As more and more people begin to pay closer attention to their dietary habits, chlorella is set to burst into the mainstream. After all, while its not a delicious dairy treat, chlorella doesn’t taste all that bad. In fact, many people love its earthy flavor!

Difference Between Chlorella and Spirulina

The two most studied and promising types of algae for human consumption are spirulina and chlorella. While they are often mentioned in the same breath, what they do in your body is night and day. Spirulina is particularly good for energy because it has no cell wall. It takes little time to digest, making it an instant source of vitamins and protein. Chlorella, on the other hand, has one of the strongest cell walls in the plant kingdom. It digests very slowly, allowing its high chlorophyll content to detoxify your body.

5 Amazing Health Benefits of Chlorella

Studies on chlorella did not stop with the research on world hunger and oxygen in space. Chlorella continues to be a well-researched food with most studies currently focusing on its health benefits. Here are some of the most impressive findings in research focused exclusively on chlorella algae:

1. Removes Toxins

Chlorella has the unique ability to bind to and remove heavy metals from the body. Studies show that chlorella is effective at removing several harmful compounds from the body, including heavy metals like lead.

When lead-exposed research mice were given a dose of chlorella at the time of lead exposure, their blood lead levels dropped an incredible 66%! The researchers attributed this to chlorella’s strong chelation properties. The researchers also found that chlorella was able to reduce blood lead levels in mice previously exposed to lead due to its ability to strengthen the immune system. [2]

One study found that chlorella counteracted heavy metal poisoning and prevented tissue damage by reducing the absorption of cadmium into the body. [3] Heavy metal toxicity, including cadmium and lead toxicity, is a problem facing many developed countries. [4]

We are exposed to these pollutants in our air, our water, our food, and the consumer products we purchase. It’s important to give your body the resources it needs to prevent pollutants for harming your health. Chlorella is a fantastic food for fortifying your body’s immune system and preventing heavy metal-related illnesses.

While not a toxin that most people try to avoid, chlorella has also been found to promote the metabolism of alcohol in humans. A study performed with 6 human subjects found that consuming chlorella before drinking alcohol reduced ethanol in the blood and breath along with reducing acetaldehyde, a contributing cause of hangovers, in the blood.[5]

2. Supports Immune System

Chlorella has been found to stimulate the production of several cell types critical to the immune system. This research was done on the short-term benefits of chlorella rather than long term, which means after just 2 months, human test subjects saw improvements in their immune system. [6] A similar study’s human subjects saw results in just 1 month. This study tested chlorella’s ability to stimulate immune function in humans. [7]

For mothers, chlorella can be a great food for helping to make sure dioxins are not transferred to infants while breast feeding. Dioxins are a group of toxic compounds that can find their way into breast milk due to poor environmental conditions. Chlorella has been found to stimulate antibodies in breast milk that eliminate dioxins. [8]

3. Lowers Cholesterol

Chlorella has multiple studies demonstrating its efficacy in improving lipid-related biomarkers. It has been found to reduce cholesterol along with triglycerides in patients with slightly above average cholesterol levels. [9] The researchers attributed these health benefits to the high levels of carotenoids α-carotene and lutein/zeaxanthin in chlorella. There have also been studies indicating chlorella can help reduce total body fat as well as blood glucose levels. [10]

4. Improves Blood Pressure

Chlorella is loaded with micronutrients and antioxidants that are important for maintaining healthy arteries, which, in turn, improve blood pressure. [11] These nutrients help reduce arterial stiffness – a problem commonly associated with high blood pressure. Some research suggests that chlorella improves arterial health byincreasing nitric oxide levels. [12] Research has used both younger and older individuals, meaning anyone can benefit from chlorella.

4. Better Aerobic Endurance

Interestingly, chlorella’s ability to increase oxygen uptake capacity was studied in both young men and women. Even more interesting, chlorella was found to significantly improve peak oxygen. [13] These findings suggests that consuming chlorella could be beneficial to athletes who participate in sports or exercise requiring significant aerobic endurance.

Ways to Take Chlorella

Most people find chlorella algae more palatable than its cousin algae, spirulina. Some people even love the taste! It has a very "green" flavor but is easier to chew than spirulina and is much less bitter. You may find chlorella to be an acquired taste, but if you don’t feel like getting used to it, you can always just swallow chlorella with some water.

Chlorella can get a bit stuck in your teeth, but hey, so does popcorn! In fact, some people like to use it as a popcorn substitute. Instead of reaching for the bag of popcorn to snack on during the movie, just grab the chlorella bag and chow down. No microwave required! It also goes well in smoothies, in trail mix, and pretty much anywhere else you’d put greens like kale or spinach.

For other people, however, chlorella’s earthy taste will just not be your thing. That can really be a problem if you opt to get powdered chlorella since you won’t be able to hide the flavor. The best foods for your health are always the ones that you will eat regularly. So, if you think you might not like the taste of “green,” then we highly recommend you try chlorella tablets so you can swallow them without tasting. It’s easy to crush tablets into a powder. It’s a little bit harder to put powder back into tablet form!

Most companies who sell chlorella use 500mg and all the way up to 1-gram tablets. We recommend 250mg chlorella tablets as they are much easier to swallow – especially if you want to give them to children.

While cooking with chlorella can be a fun way to get green colors into your foods, it’s important to know that excessive heat can damage chlorella’s nutrients. Keeping your chlorella in the refrigerator can help maintain the flavor, but you don’t have to worry about leaving it at room temperature – even on an especially hot day.

Not Just Another Supplement or Extract

It’s important to know that chlorella isn’t just another mass-produced extract from China with a few studies showing vague health benefits. Chlorella is a bona fide superfood with decades of research to back it up. It is a food crop, and just like the greens you buy at the grocery store, quality matters. Chlorella growing techniques vary, but the best chlorella is grown naturally in outdoor tanks monitored for purity.

While we cannot speak for the entire chlorella industry, the ENERGYbits chlorella growing method is all-natural. We use no artificial chemicals or pesticides. We grow the chlorella in pristine, freshwater tanks, harvest it, dry it, and press it into tablets. Our chlorella is tested three times for purity (and is consistently 100% pure) before you receive it. That means all you are getting is pure chlorella, just as nature intended!

How to Know if Your Chlorella is High-Quality

Chlorella must go through a longer process to maximize its nutrition than other crops. This leaves more room for error as a grower and for that reason, it is crucial to select a chlorella product that is grown the right way.

Many of the requirements for high quality chlorella are the same as spirulina (which you can read about on our spirulina page). These factors include growing location (Taiwan is best), whether it is grown indoors or outdoors (outdoors is best), in tanks or pools (pools are best), contaminant testing (must be 3rd-party tested), and ocean water vs. freshwater (freshwater is best) among others. There are also two other questions that you should always ask before buying:

1. What strain is this Chlorella?

There are two main strains of chlorella that are used for their health benefits - Chlorella Pyrenoidosa and Chlorella Vulgaris. There have been no studies directly comparing the nutritional benefits of these two chlorella. With that said, Chlorella Vulgaris is far more common and suspect in quality.

Many mass producers choose this chlorella for its ability to grow in less than pristine conditions, meaning the chlorella does not properly develop its most important nutrients. If chlorella is grown indoors, it will not properly develop chlorophyll, a key nutrient for detox. If the chlorella is grown in less than pristine water or without the proper nutrients, the chlorella will not contain as much protein.

As Chlorella Pyrenoidosa is more common for higher quality growers (especially in Taiwan, as this strain is native there), it often contains more protein and micronutrients. So, while some manufactures may take great care in growing high quality Chlorella VulgarisChlorella Pyrenoidosa is the safer option in our opinion.

2. How is this Chlorella's cell wall processed?

One of the most important things to know when you are looking for the best chlorella algae on the market is how the chlorella’s cell wall is processed. Chlorella has one of the hardest cell walls in the plant kingdom. In order to make its nutrients bioavailable, that cell wall must be opened.

There are many ways manufacturers process chlorella. The best chlorella has its cell wall broken by sound vibrations. The chlorella is passed through a sound chamber, cracking the cell walls without high heat or excessive grinding. This method allows the nutrition in chlorella to remain intact yet bioavailable.

Some manufacturers use chemicals or extreme heat to make chlorella digestible; however, these methods severely harm chlorella’s nutrition. More common methods include milling and pressurizing the chlorella. While using a pressure-release chamber prevents oxidization and nutrient degradation, milling chlorella can negatively affect its nutrient content and digestibility.

We highly recommend knowing how your chlorella is cracked before buying. If you cannot find out how a company processes their chlorella (or if they do not mention the chlorella’s cell wall is broken), purchasing it is very risky.


Chlorella algae is a game changer for health. Many foods are good for getting your body the nutrients it needs, but only a handful are good at removing the toxins it doesn’t. Chlorella can help cleanse your body of environmental toxins, leaving you feeling healthier than ever. If you’d like to try our soundwave cracked, chlorella (Chlorella Pyrenoidosa), then be sure to check out ourRECOVERYbits® Chlorella. It is the highest quality chlorella available and is grown using the highest quality growing conditions in the industry.
