What is spirulina?



Spirulina is a tiny single-celled blue-green alga that lives in fresh water. It's a plant that has existed on earth for over 3 billion years, is about half a millimetre in length, and appears under a microscope as long, thin, blue-green spiral threads. Strong sunlight, pure water and clean air enable spirulina to thrive, but it is highly adaptable, and is known to survive in extremely harsh conditions.

Spirulina is said to have been consumed in Mexico City as the primary source of protein for 5,000 years. Today, millions of people worldwide use spirulina daily, but it is most commonly consumed in the far east; Japan is the world's largest consumer.

Spirulina is considered one of the most nutritious foods on Earth, and NASA has used spirulina for astronauts in space. In the 1974 United Nations World Food Conference, it was announced that spirulina is “the most ideal food for mankind”. The World Health Organisation considers it "a very suitable food” and “able to be administered to children without any risk”, while The United Nations has said “there is a need for both national governments and inter-governmental organizations to re-evaluate the potential of spirulina to fulfil both their own food security needs as well as a tool for their overseas development emergency response efforts”.

What's in spirulina?



PlantPills spirulina is an extremely nutritious whole food, and is packed with vitamins, minerals, omega 6/9 fatty acids, RNA, DNA, polysaccharides, the age-fighting antioxidant enzyme superoxide dismutase (SOD), and chlorophyll, amongst others.
Spirulina has a particularly high Oxygen Radical Absorbance Capacity (ORAC) level, and is one of the highest sources of phytopigments such as beta-carotene and zeaxanthin, but is the only known source of phycocyanin, which makes up about 16% of spirulina’s weight and is known to have antioxidant, anti-inflammatory, neuro/hepto-protective, and anti-tumour properties.

Gram for gram...
  • 22 times the beta-carotene of carrots
  • 2 times the vitamin B2 of lamb liver
  • 12 times digestible protein of beef
  • 3 times the vitamin K of kale
  • Highest food source of GLA
  • Only known source of phycocyanin

PlantPills spirulina is between 60 and 70% protein, and this protein is in a pre-digested form, meaning that it is extraordinarily easy to digest, resulting in an unmatched digestibility coefficient of 95%. Unlike most foods, spirulina's cell walls are a very thin complex of natural sugars which practically dissolve upon contact with moisture and digestive enzymes.

Within moments, it is absorbed by the body, without the loss of time and energy incurred in the digestion of ordinary foods.

Spirulina has extremely high levels of EAAs (essential amino acids) that we must obtain from food, and BCAAs (branched-chain amino acids), and because the amino acids in spirulina are delivered in an essentially “free-form” state, there is almost instantaneous assimilation, allowing rapid protein synthesis.

BCAAs are often used to improve exercise performance and recovery, and to reduce muscle breakdown. It is no surprise that these are some of the benefits observed in studies involving athletes.

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

What are the benefits?



Age-fighting antioxidants

Spirulina is a potent mixture of antioxidants and most of Spirulina’s health benefits are associated with its antioxidant pigments. These are carotenoids (mixture of carotenes and xanthophylls), chlorophyll and the unique blue pigment phycocyanin. Among these pigments, the xanthophyll zeaxanthin is rare in nature, and 3 g Spirulina can provide adequate quantities of this very valuable xanthophyll. Phycocyanin is even rarer in our diet and 3 g Spirulina can provide adequate quantities of this highly beneficial pigment.

Tissue preservation

Spirulina is the world's best source of the anti-oxidant superoxide dismutase (SOD). The superoxide molecule is one of the most tissue damaging substances within the body. SOD is a biological adaptation specifically designed to destroy the superoxide radical and to protect against any subsequent tissue damage. Inadequate superoxide dismutase formation leads to accelerated aging and tissue degeneration.

Eye health

Spirulina is very rich in carotenoid anti-oxidants. It has 22 times the amount of beta carotene (a form of vitamin A) per volume of carrots. Spirulina also contains high levels of zeaxanthin and lutein. These antioxidants are very important for good vision and overall eye health.

According to a study by Orient Medical Science University of Japan, dietotherapy with spirulina had an 80% effectiveness on 480 cases of senile cataracts, diabetic retinopathies, and hypertensive retinopathies.

Blood

Spirulina is a powerful blood cleanser due to its rich source of chlorophyll. It contains roughly ten times the amount of chlorophyll in green vegetables per volume. Chlorophyll helps build red blood cells in the body and provides an easily absorbable form of magnesium. This combination helps oxygenate the blood stream and removes organic toxins.

Phycocyanin and allophycocyanin, which help to form the blue colour within spirulina (along with anthocyanins), have been shown to increase white blood cell counts.

Anti-inflammatory

A second 2002 study at Havana’s Ozone International Center showed that phycocyanin from spirulina acted as an anti-inflammatory in protecting live mice which had been injected with arthritis-inducing Zymosan. The mice showed no cartilage damage and an inhibited inflammatory response after receiving spirulina for eight days following their Zymosan injections. The animal nutritionals maker Pharma Chemie of Syracuse, NY has since gone on to patent a compound containing phycocyanin, which gives spirulina its blue-green color, as an anti-inflammatory for use in animals.

Skin health

The combination of SOD and carotenoids within spirulina make it very good for skin care. It is renowned for improving ageing spots, eczema, acne, & rashes.

Gut health

Spirulina has strong anti-microbial effects that help create balance in the gut flora. It does this by controlling the growth of pathogenic bacterialike e-coli and yeasts in the digestive system. This is critical for optimal digestion and nutritional absorption because healthy flora increase absorption of nutrients from the foods we eat, and protect against infection.

Brain health

A study published in the May 2005 issue of the journal Experimental Neurology found that the brains of aged rats fed spirulina supplements maintained their neuron function much better, and showed far less free radical damage than those of rats fed cucumbers. The research is significant because it indicates that spirulina may be helpful in warding off the free radical damage related to aging diseases like Parkinson’s and Huntington’s Disease.

Spirulina is a rich source of the tough to find essential omega-6 fat GLA. The human brain is around 80% fat, and tissues in the brain require fatty acids such as GLA for brain function and growth. Human breast milk contains high quantities of GLA because infants need to build brain mass quickly in order to boost their chances of survival. A bigger, better brain improves a child's ability to comprehend language, and helps with social interactions, environmental cues, and interpreting sensory input.

Gene preservation

Several studies involving mice and dogs have shown that spirulina provides protection against genetoxicity induced by cisplatin, urethane, cyclophosphamide and mitomycin-C, and consistently increased the level of red cells, white cells, and haemoglobin in blood and nucleated cells/DNA in bone marrow. Polysaccharide from spirulina reduced hematopoietic damage induced by cyclophosphamide and Cobalt-60 irradiation.

Stem cell protection

In a study published in 2010 by PLoS One, spirulina appeared to enhance stem cell proliferation in rats.

Testosterone preservation

In a study published in 2013 by PLoS One, spirulina preserved testosterone levels in rats exposed to oxidative toxins known to reduce testosterone levels. It is also noteworthy that the group given spirulina without being exposed to the toxin did not experience an increase in testosterone levels.

This suggests that spirulina is able to maintain normal testosterone levels when a toxin is present, and if no toxin is present, it does not affect testosterone levels.

Who can benefit?



Children

A study in 1995 by Universidad Centro Americano found an 81 percent improvement in academic scores when children took just one gram of spirulina every day for six months.

A study published in the December 2000 issue of Acta Psychiatrica Scandinavica, in which 109 children took one gram of blue-green algae daily for 10 weeks, found most of the children showed significant improvement in their ability to focus, concentrate, and follow directions.

Athletes

A study published in Ibnosina Journal of Medicine and Biomedical Sciences in 2010, found that supplementing with 2 g spirulina per day for 8 weeks was able to increase muscle size and strength of subjects compared to those receiving a placebo.

Another study, published in Medicine & Science in Sports & Exercise in 2009, found that supplementing with 6 g of spirulina per day for 4 weeks was able to increase exercise performance, fat oxidation, and reduce oxidative damage by free radicals.

The men ran on a treadmill for two hours every day, running at 70-75% of their VO2 max and 95% of their VO2 max to exhaustion. Both exercise performance and respiratory function were measured. Blood samples were drawn at regular intervals during the study. The time to fatigue after the two hour run was significantly longer among the men who took spirulina. The carbohydrate oxidation rate was decreased by over 10% and the fat burning rate was increased by almost 11% over the placebo group. The study concluded that spirulina really does enhance exercise performance.

A 1998 study published in XXIV FIMS World Congress of Sports Medicine in June 1998, found that supplementing with spirulina tablets resulted in an improvement in iron reserves, which can optimize athletes' health and physical capacity. Clinical symptoms such as exhaustion, muscle fatigue and somnolence, which can be a result of depleted iron reserves, were reduced after supplementation with spirulina, and the resulting correction of the iron deficiency.

A 2006 study published in the journal Applied Physiology found that ingestion of spirulina in addition to normal diet showed a preventive effect of the skeletal muscle damage following exercise, and that probably led to postponement of the time of exhaustion during the all-out exercise.

Nutritional Rehabilitation

Spirulina has been used as a health food supplement for malnourished children and adults in clinical studies since the early 1970s.

In 1993, India had a one year feeding program of 1 gram per day of spirulina with 5,000 preschool children for at least 150 days, and found that the spirulina supplemented diet reduced the occurrence of "Bitot's spot", a symptom of vitamin A deficiency, from 80% to 10%

Radiation exposure

Spirulina works so well at mitigating the damage caused by radiation that it was actually awarded a Russian patent in 1995 for improving the immunity of children affected by radiation from the Chernobyl disaster. Many children became stricken with chronic radiation sickness and elevated Immunoglobulin E (IgE) levels, and they also tested positive for high allergy sensitivity. But upon consuming roughly five grams (g) of Spirulina a day for 45 days, the children's IgE levels and allergic sensitivities were restored back to normal.

A 2001 study conducted by researchers from the Medical and Pharmaceutical Academe of Yangzhou University in China found that Spirulina extracts effectively protect against both the damage caused by chemotherapy drugs and the damaging effects of gamma radiation exposure.

People with poor diet

A study published in the Life Sciences journal in 1993 found that increases in hepatic triglyceride levels in rats fed fructose were reduced significantly by supplementation with spirulina.

Hypochronic anaemia

A study in 1987 by Tokyo Medical and Dental University found that hypochronic anaemia was successfully treated (haemoglobin content increased 21% from 10.9 to 13.2) after subjects took 4 grams of spirulina after each meal for 30 days.

Elderly

A 2011 study suggests that spirulina may help boost a weakened immune system and reduce the risk of anaemia in the elderly. Forty adults, aged 50 and over, with no chronic diseases, took 3g of spirulina daily for 12 weeks.

After 6 and 12 weeks of therapy, the researchers performed complete blood cell counts, and found that spirulina led to increases in IDO activity and haemoglobin. The authors concluded that "spirulina may ameliorate anaemia and immunosenescence in older subjects".

Recovery from stroke

A study published in Experimental Neurology in 2005 found that after a stroke, rats fed a spirulina enriched diet had stroke lesions that were 75% smaller than those in the control group. The rats fed spirulina also recovered mobility to a greater extent.

Allergy and hay fever

A randomized, double-blind clinical study published in the Spring 2005 isssue of the Journal of Medicinal Food indicated that allergic rhinitis (nasal allergy) sufferers given a daily 2 g dose of spirulina for twelve weeks, made a significant improvement in their allergy symptoms. There was no improvement for the participants taking the placebo.

Why PlantPills spirulina?



PlantPills spirulina is grown in vast mineral rich fresh water “raceway” type ponds by Parry Nutraceuticals in India, the only spirulina producer in the world to be certified by the U.S. Pharmacopeial Convention (USP) under their Dietary Ingredient Verification Program. Parry have been cultivating spirulina for over 30 years, and are acknowledged to be among the very best producers of spirulina in the world.

PlantPills spirulina contains more gamma linolenic acid (GLA), vitamin K, vitamin B2, chlorophyll and crude phycocyanin than any other known source in the world.

A concern for anyone who consumes spirulina is the potential contamination of spirulina with blue green algae strains of AFA (Aphanizomenon flos-aquae), some of which produce microcystins, which are known to be hepatoxic (toxic to the liver) and carcinogenic (cancer causing).

PlantPills Spirulina Pouch and Tablets

PlantPills spirulina tests negative for microcystins, at a stringent detection limit of half a part per billion. It also tests negative for the neurotoxin BMAA. Frankly, if every batch of spirulina is not tested to this level, it cannot be deemed certain to be safe for human consumption.

PlantPills spirulina is cultivated using vegetarian organic nutrients (no animal products or Chilean Nitrate are added), is suitable for vegans, is non-GMO, is gluten free, herbicide and pesticide free, and although Parry have obtained organic certifications from USDA and OCIA (USA), Ecocert (France), and Naturland (Germany), PlantPills has not yet applied for organic certification in the UK, so we can not yet claim that our spirulina is organic, and do not sell it as organic.

PlantPills spirulina comes in powder or 200 mg tablets, significantly smaller and easier to take than the larger 500mg supplied by the majority of producers.

Every batch of PlantPills Spirulina 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.

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

PlantPills spirulina is supplied in our unique PillFresh™ packaging, which keeps the spirulina sealed in an environment with an oxygen content of less than 0.1%. After you open your PlantPills spirulina, 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 spirulina fresh.

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

Other vendors package spirulina tablets in plastic tubs, or "vacuum sealed" aluminium pouches. Plastic tubs are permeable to oxygen, so are no use for keeping spirulina 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 spirulina 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 spirulina is the same



Unfortunately, not all spirulina is the same. It is very important to know the source of the spirulina 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 spirulina comes from reputable companies which have been producing spirulina for decades. Such companies have vast experience and knowledge of growing, harvesting and processing good quality spirulina. They will provide Certificate of Analysis' (COAs), completed by third party testing labs. This ensures the spirulina is of a high quality and is safe.

If the vendor or retailer of the spirulina 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 spirulina.

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



Spirulina 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.

Spirulina 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, spirulina from China (or anywhere else for that matter) is not a verifiable, reliable, good quality source of safe spirulina.

Dosage and guidelines



It is sensible for anyone who is new to taking spirulina, 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.

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

Human studies have shown that spirulina is safe for human consumption and daily consumption of approximately 4 g per kg of body weight did not result in any adverse effects, even in infants and young children. No member of the genus spirulina is known to be toxic.

Spirulina 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 spirulina. These changes are temporary, and things should be back to normal within a number of days.

Recommended dosage: Build up to 5 grams (25 tablets/2x level 5ml teaspoons of powder) per day, with water.

Upper dosage: 30 grams (150 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 (75-150 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. Vigorous stirring with a fork may be required, as spirulina can be prone to clumping.

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

Some people like to take spirulina 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 spirulina in combination with chlorella.

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

To compare our spirulina 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 Spirulina Tablets below.

PlantPills Spirulina Tablets Label

Tablets or powder?



PlantPills Spirulina comes in two versions, the powder form and the tablet form. The tablets are 100% spirulina 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.

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

Spirulina 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.

Warnings



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

Most people will experience detox symptoms when first taking spirulina.

Spirulina contains iodine, to which some may be allergic.

Spirulina contains phenylalanine. The genetic disorder phenylketonuria (PKU) is the inability to metabolize phenylalanine. Individuals with this disorder are known as "phenylketonurics" and must regulate their intake of phenylalanine.

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

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

It is easier on the digestive system to take spirulina 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 spirulina, or use caution and follow the advice of their healthcare professional because spirulina contains high amounts of vitamin K that may affect the inhibition of blood clots.

Spirulina 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 spirulina.

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