What is chlorella?

Chlorella is a tiny single-celled green alga that lives in fresh water. It's a plant that is about the same size as a human red blood cell, and has existed on earth for over 3 billion years. Strong sunlight, pure water and clean air enable chlorella to multiply at an incredible rate, and the entire reproduction cycle is complete within 24 hours.

PlantPills chlorella is grown in vast mineral rich fresh water cultivation ponds by the largest and oldest chlorella producer in the world, Taiwan Chlorella, who produce over 400 tons a year, and are acknowledged to be among the very best producers of chlorella in the world.

PlantPills chlorella is the best chlorella in the world, renowned not only for it's high content of chlorophyll, chlorella extract and RNA/DNA, but crucially it is highly digestible and truly rich in vitamins, minerals and protein.

What's in chlorella?

PlantPills chlorella is an extremely nutritious whole food, and is packed with vitamins, minerals, omega 3/6/9 fatty acids, RNA, DNA, CGF and chlorophyll, amongst others.
Chlorella contains the highest amount of any known food for several of these, such as chlorophyll (6 times that of wheatgrass), vitamin D (4 times that of herring), and lutein (6 times that of kale).

Gram for gram...
  • 9 times the beta-carotene of carrots
  • 5 times the iron of duck liver
  • 2 times the protein of beef
  • 2 times the vitamin K of kale
  • 2 times the calcium of whole milk
  • 8 times the RNA of sardines

PlantPills chlorella has extremely high levels of EAAs (essential amino acids) that we must obtain from food, and BCAAs (branched-chain amino acids), which are absorbed directly into the circulatory system, allowing rapid protein synthesis profiles, far superior to other whole foods. BCAAs are often used to improve exercise performance and recovery, and to reduce muscle breakdown.

PlantPills chlorella has a particularly high omega 3/6/9 essential fatty acid content, in amounts comparable to purpose built supplements that use extracts and isolates, and yet chlorella is a vegetarian whole food.

NASA has studied using chlorella as one of the first whole foods in space on the international space station.

What are the benefits?


The Journal Neuroscience Letters published a study in October 2009 which showed how Chlorella supplements decreased cognitive decline in old mice as well as lowering age-related oxidative stress.

It is said that mental exercise exhausts RNA from the brain, and as chlorella is an excellent source of RNA, it could help improve mental alertness and endurance.

Helps fillings/heavy metals

Amalgam or "silver" fillings contain mercury, one of the most potent nerve toxins on the planet, and emit a steady stream of mercury vapour which gets absorbed into the body. Sometimes, parts of these fillings can crack or break off and are accidentally swallowed.

Chlorella can help protect against this mercury by escorting the mercury out of your body before it can do damage.

A three-year double-blind metal detoxification study with over 350 people participating was undertaken at a Russian metal foundry, where more than 20 natural compounds were used in trials to remove heavy metals from people who had been exposed at very high levels to four main metals (antimony, lead, cadmium and arsenic).

The trial used broken cell wall chlorella combined with cilantro, and eliminated all heavy metals including mercury, with no reported side-effects.

Mitigates smoking damage

In a study published in the August 2009 issue of the health journal Nutrition, chlorella was shown to decrease the DNA damage suffered by smokers from the use of tobacco.

Chlorella was also shown to increase systemic antioxidant enzymes levels, and levels of other antioxidants such as vitamins E and A.


A number of components collectively referred to as chlorella growth factor, or CGF, are believed to be one group of compounds in chlorella that give it its health-promoting ability.

CGF has been shown to stimulate the immune system, accelerate healing, repair and maintain healthy tissues, increase energy levels, and revitalize and fortify the entire body at the cellular level.

Treats body odour

Chlorella can significantly reduce or eliminate bad breath and body odour, thanks to its extraordinarily high chlorophyll content.

A study by Dr. Westcott published in a July 1950 Time magazine article found that chlorophyll taken daily could neutralize bad breath, body odour, menstrual odours, and foul-smelling urine and stools.

Nerve tissue

CGF (chlorella growth factor), which is found in the nucleus of the chlorella cell, promotes the body's innate healing ability to grow and repair nerve tissue throughout the body.

People suffering from degenerative nerve disorders typically report positive results from using chlorella.


Chlorella contains the highest amount of lutein (also known as Xanthophyll) of any plant, 6 times that of the next highest, kale.

Lutein is very important for long term eye health, and is especially concentrated in the macula, our true centre of sight at the back of the retina. This aids absorbtion of the damaging blue rays from the light spectrum.

Studies published in American Journal of Epidemiology, Ophthalmology and Archives of Ophthalmology found that higher levels of lutein and zeaxanthin in the diet are associated with a lower incidence of age-related macular degeneration.

Stomach conditions

Effective treatment of peptic ulcers using chlorella is now well established in Japan, as well as treatment of duodenal ulcers and gastritis.

Chlorella has been shown to offset the stress of high levels of bile in a study involving rats. The condition normally causes excessive bacterial overgrowth with consequent translocation of large amounts of bacterial toxins into the bloodstream. Chlorella removes the bacterial toxins from the circulation, prevents the free radical damage that would otherwise be caused by the jaundiced condition, and prevents atrophy/damage of the digestive lining.

This study is important because millions of humans have stagnant and inappropriate bile flow and excess unconjugated bile buildup.


Chlorella contains the highest percentage of chlorophyll in the known plant world.

The chlorophyll molecule is very similar to the haemoglobin molecule in blood, and it can act as an effective cleanser in the bowel, kidneys, liver and bloodstream.

A study in Taiwan showed that Chlorella was as effective as milk thistle in terms of protecting the liver of lab rats against damage caused by chemicals. This is significant because milk thistle was hitherto considered to be the best remedy for supporting liver health.

A Japanese study found that taking 4-5 grams of chlorella before drinking alcohol can prevent a hangover 96% of the time, even after a night of excessive drinking.


One of the benefits of chlorella's ability to strengthen and detoxify the liver is clearer skin, because there are lower levels of toxins in the blood to irritate or come to the surface of the skin.

In addition, chlorella also contains high levels of beta carotene, vitamins A and E, iron, zinc and omega-3 fatty acids. All of these nutrients contribute to healthier skin and reduced inflammation, resulting in fewer breakouts.

Beta carotene can provide you with protection from harmful sun rays, and omega-3 fatty acids help nourish cell membranes which act as a barrier to harmful substances, but also are the passageway for nutrients and waste products to effectively pass in and out of the cell.

There is a case study from Japan which documented a patient with a severe skin wound. Three weeks of conventional treatment failed, and it was only after chlorella was administered, that accelerated skin healing and reduced infection were observed, resulting in the complete healing of the wound.

Intestinal health

Chlorella stimulates the growth of friendly bacteria, which in turn has the probiotic effect of strengthening gut flora and resisting disease.

A Japanese study in 1957 found that chlorella promoted rapid growth of lactobacillus, one of the bacteria that promotes colon health. The chlorophyll in chlorella helps to keep the bowel clean, and the tough cellulose membrane binds to cadmium, lead and other heavy metals and carries them out of the body.

Chlorella is uniquely designed not to bind to the minerals which your body naturally needs to function optimally. It does not bind to beneficial minerals like calcium, magnesium, or zinc.

Chlorella can help to restore bowel regularity, normalise beneficial bowel flora, assist in detoxifying the bowel and stimulate repair of damaged, broken down tissue.


Chlorella can help you age-proof your body because it contains the richest source of age-fighting RNA and DNA found in any food.

DNA is a chemical blueprint for new cells and sends out RNA molecules like a team of well-trained workers, which make it possible for your cells to reproduce themselves.

RNA and DNA are the key nutritional factors for longevity, allowing you to stay young, healthy and vibrant. In addition to improving the inner workings of your body, RNA and DNA have been shown to have considerable beauty benefits. As we age, both the quality and quantity of RNA and DNA diminish. Cell construction suffers, cells become vulnerable to all sorts of problems, and you look and feel older than your years. This is why replenishment of your body’s supply of RNA and DNA is so important.

As you fuel your body with these nucleic acids, you may find your skin will look younger and your energy levels will rise to where they were years ago.

Preserve telomere length

Telomers cover the ends of DNA, and shorter telomere length has been associated with aging.

In a study published in the January 2010 issue of The Journal of the American Medical Association, 608 people were tested over a 5 year period for omega 3 fat levels, and telomere length.

The study found that the people with the slowest rate of telomere length shortening had the highest amount of omega 3 fatty acids.

PlantPills chlorella is particularly rich in omega 3 fatty acid, but most other chlorella is not.

Who can benefit?

Alcohol consumers

People who drink alcohol can benefit due to chlorella's remarkable liver nourishing properties.

One study found that taking 4-5 grams of chlorella before drinking alcohol can prevent a hangover 96% of the time.

Anecdotal reports suggest that the best results for avoiding a hangover are achieved by taking 5-10 grams a few hours before alcohol, and then again first thing in the following morning with water.

It has also been said that chlorella can reduce the urge to drink alcohol in alcoholics.


Children may be able to benefit from taking chlorella. One study in Japan showed that when a group of healthy 10 year olds were given just two grams of chlorella a day for nearly 4 months, dramatic increases in growth were recorded when compared to the control group.

This has also been replicated in a study on young rats, rabbits, chicks and pigs. Adding 5 to 10 percent of chlorella to their regular feed resulted in dramatic increases in growth of between 10 and 47 percent over control groups.

Common cold sufferers

People who are susceptible to colds may be able to benefit from taking chlorella. A Japanese study conducted on sailors of the marine defence fleet during a three month voyage found that sailors who did not take chlorella daily suffered 41% more cold viruses than those that took 2 grams per day.

It also found those taking chlorella were much more resistant to weight loss, with the sailors not taking chlorella losing more than double that of the chlorella group.

People with poor diet

People with poor diet can benefit in a variety of ways. A trial was published in the Journal of Medicinal Food in October 2009 which reported that the addition of chlorella to a poor diet “may prevent insulin resistance” in diabetes-prone rats.

The average person does not get enough green vegetables in their diet, and chlorella helps compensate for that.

Chlorella is the highest known source of RNA. Insufficient nucleic acid (RNA/DNA) causes premature ageing as well as weakened immunity, and is depleted by lack of exercise, stress, pollution, and poor diet.

People following a diet high in processed, animal and junk food are in greatest need of detoxifying and cleansing. Chlorella is the highest known food source of chlorophyll, which exceeds at cleansing and detoxifying the body.


Smokers may be able to benefit from taking chlorella. Chlorella has been shown to decrease the DNA damage suffered by smokers from the use of tobacco in one study. Chlorella was also shown to increase systemic antioxidant enzymes levels, and levels of other antioxidants such as vitamins E and A in the smokers.

Radiation exposure

Chlorella is able to both prevent and heal radioactive damage. A study in Japan found that 8 grams of chlorella given to animals daily resulted in seven times more cadmium eliminated in urine, and three times more in faeces.

Other studies have confirmed this, finding that chlorella protects from, and mitigates the damage caused by both acute and chronic radioactive damage, and it greatly improved survival rates among mice irradiated with lethal doses of radioactive gamma rays.

Chlorella also has detoxification potential for similar compounds, such as dioxin and PCBs (chemical compounds used in plastics, insulation, and flame retardants, with potential to cause cancer and liver damage).

Stimulant consumers

People who drink tea, coffee or energy drinks may be able to benefit. Although it might not be as tasty, trendy, or sociable, anecdotal reports suggest that taking chlorella in place of a morning coffee or sugary drink can provide a similar boost in energy and alertness, without the lows that are associated with caffeine and sugar. This may be due to chlorella being such a rich source of B vitamins.


Athletes, sportsmen and sportswomen may be able to benefit from taking chlorella.

One study found that mice fed chlorella could swim for twice as long as the control group after just 14 days. In this same study, blood levels of lactic acid in the chlorella intake mice were higher than that of the control group, suggesting that chlorella may be able to help diffuse lactic acid out of the muscle cell into the blood more efficiently.

Studies have also shown chlorella to have anti-inflammatory properties in both humans and rats. This is useful for recovery after performance in athletes, but also during treatment of injuries.

Ruben Tabares, a strength & conditioning coach and nutritionist, recommends chlorella to everyone that he trains. Ruben has worked with Premiership footballers, P Diddy, and boxers David Haye and Amir Khan. He finds chlorella helps reduce inflammation and dissipate lactic acid.


Chlorella may be beneficial to people who are elderly, sick or injured. Chlorella has been shown to decrease cognitive decline in old mice as well as lowering age-related oxidative stress. Chlorella also contains an extraordinarily high content of age fighting RNA and DNA.

Chlorella could be helpful for people with anaemia (chlorophyll stimulates the production of red blood cells), arthritis (chlorella is excellent for reducing acidity in the body, and since acidity can worsen joint pain, balancing the body's pH level by making it more alkaline could help relieve arthritis pain), cardiovascular disorders (chlorella is rich in magnesium and omega-3 oil which are known for maintaining heart function and protecting against heard disease), digestive problems and weak digestive absorption (chlorella contains digestive enzymes and causes the friendly lactic bacteria in the intestine to multiply more rapidly than usual, improving digestion and the absorption of nutrients).

Daily dietary supplementation with chlorella may reduce high blood pressure, lower serum cholesterol levels, accelerate wound healing, and enhance immune functions. The addition of chlorella to a poor diet “may prevent insulin resistance” in diabetes-prone rats.

Chlorella has also been shown to decrease weight loss and reduce colds.

However, it is important to remember that chlorella is a whole food, not a medicine, and we are not advising chlorella to diagnose, treat, cure or prevent illness or disease.

Why PlantPills chlorella?

PlantPills Chlorella Pouch and Tablets

PlantPills Chlorella comes from Taiwan Chlorella Manufacturing Company, who have been making premium grade chlorella for nearly 60 years. They are the world's largest, oldest, and most technically advanced producer of chlorella, and are considered to be among the very top producers in the world in terms of purity and bioavailability.

The cell wall of chlorella must be cracked or broken to enable humans to digest it. To crack the cell wall of PlantPills chlorella, the pressure is raised in the holding tank where the chlorella is stored, and then the pressure is suddenly released.

This advanced pressure method is patented, and much superior to older, cheaper methods such as milling, which often result in problems with lower digestibility and reduced nutritional value.

PlantPills chlorella (cracked cell wall, strain: Chlorella Pyrenoidosa) comes in powder or 250 mg tablets, significantly smaller and easier to take than the larger 500mg supplied by the majority of producers.

Every batch of PlantPills Chlorella is independently verified by third-party laboratories to have no dangerous levels of heavy metals or micro-organisms. The certifications for the current batch are viewable below. Every single batch is thoroughly tested in-house to confirm the absence of BMAA/microcystin.

Pack sizes are 250 grams, 500 grams, 1 kilogram, 2 kilograms and 10 kilograms (selectable in the basket).

Our PillFresh™ packaging

It is imperative that chlorella is transported and stored in an oxygen-free environment, even after opening. If chlorella is exposed to oxygen, the nutritional value quickly starts to diminish, because vitamins, enzymes and antioxidants are particularly sensitive to oxygen.

PlantPills chlorella is supplied in our unique PillFresh™ packaging, which keeps the chlorella sealed in an environment with an oxygen content of less than 0.1%. After you open your PlantPills chlorella, just seal it back up, and incredibly, our unique PillFresh™ packaging will again reduce the oxygen content to less than 0.1%, continuing to keep the chlorella fresh.

This packaging will continue to do this time and time again, for 40 openings.

Other vendors package chlorella tablets in plastic tubs, or "vacuum sealed" aluminium pouches. Plastic tubs are permeable to oxygen, so are no use for keeping chlorella fresh. Tablets in aluminium pouches are difficult to vacuum seal, and this type of vacuum sealing typically contains at least 2% oxygen. This is enough oxygen to start diminishing the nutritional value, and considering mould can grow in air with a 0.3% oxygen content, this really isn't acceptable.

It is therefore pretty certain that a significant amount of nutrition is lost before a typical package of chlorella is even opened by the consumer. Then, after opening, the exposure to oxygen quickly starts to diminish the nutritional value further. While our PillFresh packaging maintains 100% (or very close to 100%) of the nutrients, typical packaging will result in a 37% loss in beta carotene content after four weeks, and an 85% loss in chlorophyll content after 8 weeks.

PillFresh™ packaging is truly innovative, and exclusive to PlantPills.

Not all chlorella is the same

Unfortunately, not all chlorella is the same. It is very important to know the source of the chlorella you eat, as it has a huge bearing on whether it is as nutritious as it should be, and if it is even safe to consume.

The best quality chlorella comes from reputable companies which have been producing chlorella for decades. Such companies have vast experience and knowledge of growing, harvesting and processing good quality chlorella. They will provide Certificate of Analysis' (COAs), completed by third party testing labs. This ensures the chlorella is of a high quality and is safe.

If the vendor or retailer of the chlorella for sale can not or will not provide you with the name of the producer, and a COA from a third party (a document from the testing lab, NOT the producer or vendor), do not buy the chlorella.

With no producer or valid COA (not just numbers typed into a website or an email from the vendor), you really don’t know what you are buying. It doesn’t matter if it’s even labelled as organic, from “pristine waters of Hainan, China”, or have impressive looking claims on their website, you really don’t know what you are buying.

China is not a reliable source

Chlorella from China can be animal feed grade (not safe for humans), cut with fillers, roasted for a long time at very high temperatures in an attempt to kill harmful bacteria (the roasted, nutty smell is obvious), have high levels of heavy metals, or could even be contaminated.

An analysis of contaminated algae product for sale (by the FDA in America) found adult flies and adult fly fragments, maggots and maggot fragments, ants and ant fragments, cicada and cicada fragments, hundreds of other insect fragments, ticks, mites, ostracods, rat or mouse hairs, bird feathers, and water fleas.

In 2008, a Chinese milk scandal was exposed in which 6 babies died and hundreds of thousands of others became ill after melamine was added to raw milk to make it appear higher in protein. This further damaged China’s reputation for producing safe and reliable food products.

Chlorella from China is the cheapest available, and is often classified as organic. However, the "organic" classification has no relevance to nutritional content, purity, or contamination.

The fact is that without even knowing the producer, and without having regular nutritional and safety analysis from a reputable third party laboratory, chlorella from China (or anywhere else for that matter) is not a verifiable, reliable, good quality source of safe chlorella.

Dosage and guidelines

It is sensible for anyone who is new to taking chlorella, to take just half of one tablet and monitor themselves for any adverse reactions for 24 hours. If there is no reaction, increase the dose to one tablet the following day, and gradually build the dose up day after day.

Chlorella is a whole food, not a medicine, so there is no upper dose. Many people who supplement their diet with chlorella do not take enough for it to be effective.

In 2001 Dr. R. E. Merchant, professor of anatomy and neurosurgery at the Medical College of Virginia, stated in his study: "No toxic effects have ever been observed in laboratory animals or humans who have consumed chlorella, regardless of whether the cell wall was intact or broken."

Chlorella is a natural cleanser and helps to eliminate toxins from the body, especially when it is first taken. Some people may experience changes in their digestive systems for the first few days of taking chlorella. These changes are temporary, and things should be back to normal within a number of days.

Recommended dosage: Build up to 5 grams (20 tablets/2x level 5ml teaspoons of powder) per day, with water.

Upper dosage: 30 grams (120 tablets/12x level 5ml teaspoons of powder) per day, with water, for a healthy, active adult.

Normal maintenance dose for a healthy, active adult can be 15-30 grams (60-120 tablets) per day, split at different times of the day.

To consume the powder, place 40ml (1.5oz) of water per 5ml teaspoon of powder into a cup, add powder, stir, and drink.

Some people like to take chlorella in one go, and some like to split their dosage up between 2-3 times during the day.

Some people like to take chlorella before eating, some with their meals, and some between meals. It doesn't really matter; whichever is most convenient and effective.

It is common, and perfectly fine to take chlorella in combination with spirulina.

All information relates to PlantPills chlorella only (not chlorella in general - other chlorella is generally far less nutritious). The testing and analysis has been independently carried out by Japan Food Research Laboratories, and the raw reports can be viewed in the Why PlantPills chlorella? section above.

To compare our chlorella to that from a different supplier or producer, a similarly detailed independent report would be required.

Please see the label from our 250 gram pack of Chlorella Tablets below.

PlantPills Chlorella Tablets Label

Tablets or powder?

PlantPills Chlorella comes in two versions, the powder form and the tablet form. The tablets are 100% chlorella powder (never any excipients, anti-caking agents, binders or fillers) pressed into tablets, and are in a form that some people may find more convenient to consume.

Chlorella tablets are more suited to those that do not like the taste of chlorella powder, or those who take it on the move, and can’t easily measure and mix powder into water.

Chlorella powder is more suited to those that have difficulty swallowing tablets, or otherwise find it more convenient to consume as a drink.

From a scientific perspective, powder offers a much higher surface area available immediately higher up in the digestive tract, which may result in increased or more efficient absorption of some nutrients.


Anyone who has a seafood allergy may be particularly sensitive to chlorella.

Most people will experience detox symptoms when first taking chlorella.

Individuals lacking the digestive enzyme cellulase may not be able to tolerate chlorella. In such cases it is advisable to take a digestive enzyme supplement that contains cellulase to help digest foods such as chlorella.

PlantPills chlorella is amongst the most nutritious in the world, so if you are switching from using a different brand of chlorella, it would be sensible to take half your normal dose to begin with and adjust the dosage from there.

Chlorella contains B vitamins which are linked to increased energy. Some people may experience difficulty in sleeping if taking a large dose of chlorella just before bed.

It is easier on the digestive system to take chlorella separately from milk or other dairy products such as yoghurt or cheese.

Persons taking the blood-thinning drug known as Coumadin (generic warfarin) are advised to completely avoid chlorella, or use caution and follow the advice of their healthcare professional because chlorella contains high amounts of vitamin K that may affect the inhibition of blood clots.

Chlorella may cause the immune system to become more active, and this could increase the symptoms of autoimmune diseases. If you have one of these conditions, it’s best to avoid using chlorella.

It is never advisable to start taking a new food supplement such as chlorella during pregnancy.
