Sprirulina Powder Analysis and Special Offers

Spirulina Powder, Scientific Evidence and Market Analysis

In the last 25 years Spirulina (and Spirulina Powder as one of the basic forms) was always a hot topic in all the websites and blogs about healthy nutrition. A lot of was written about the health benefits of consuming Spirulina. Some nutrition specialists recommend Spirulina nutrition against difficult diseases like oral cancer, liver disorders, allergic reactions and many more. Although there are some objections about the specific role of Spirulina nutrition in the therapy of clinical conditions, almost all researchers agree that the nutritional benefits from this blue-green algae are extraordinary. Some of them indicate Spirulina as one of the most complete foods in the planet.

One of the most complete foods in the planet

This claim is also supported by both National Aeronautics and Space Administration (NASA) and the European Space Agency (ESA) which are researching Spirulina as one of the primary foods during long-term space missions or in case of colonization of other planets (you can find all the references for Spirulina in the NASA website here). That's why a lot of nutritionists recommend consuming Spirulina in a daily basis, not just under bad health conditions.

Spirulina Powder, Spirulina Tablets and other forms

Spirulina Powder is the most common form of Spirulina in the market and it has, as all the supplements in powder form, the best and the faster absorption rates. Also the price rate is one of the best from all the available forms. Another advantage is that Spirulina Powder is less processed than other forms because it is the basic and the first producing form from Spirulina cultures.

Spirulina Tablets and Spirulina Capsules are the other two common forms of Spirulina in the market which are best if you can't habituate the taste of the powder form. Also we have to mention that Spirulina Capsules have faster absorption rates than Spirulina Tablets because they contain powder in capsule so it is easier to digest them.

Spirulina. Supplement or Food?

This is a very interesting question because it queries our perspective on some new foods in our nutrition.

In South Africa and in Mexico where Spirulina grows naturally in some lakes, the locals are handling Spirulina as a normal food from nature. All the rest of us we have to go to a store and buy Spirulina in a package. Specially for Spirulina Powder, which we can use in everyday cooking like flour, salt or sugar (only much more healthy), we have to rethink it and consider it not as an extra supplement but like a normal food we buy from a grocery shop. The only main difference is that this food is one of the most complete and healthy foods from mother nature.

What exactly is Spirulina? Spirulina History.

Spirulina is a drum-dried cyanobacterium (blue-green algae) that can be consumed by humans and other animals and is made primarily from two species of cyanobacteria: Arthrospira platensis and Arthrospira maxima (old species name are Spirulina platensis and Spirulina maxima, and there are also other related species with the same features). Once classified as the blue-green algae, it does not strictly speaking belong to the algae, even though for convenience it continues to be referred too in that way. It grows naturally in the alkaline waters of lakes in warm regions. Measuring about 0.1 mm across, it takes the form of tiny green filaments coiled in spirals of varying tightness and number, depending on the strain.

It has been used as food for centuries by different populations and only rediscovered in recent years.

Two populations a) Massakory, Lake Chad at Republic of Chad and b) Lake Texcoco, Mexico City), approximately 10,000 km apart, discovered independently and exploited the nutritional properties of Spirulina. Perhaps this is the only record of traditional use of a microbial biomass as a food for human consumption.

Evaluation of the nutritional characteristics confirmed that drum-dried Spirulina (species Spirulina platensis or Spirulina maxima) represents a valuable source of alimentary protein.

Careful evaluation of several parameters let to the conclusion that Spirulina represent protein sources as good as legumes, including soybeans.

The benefits of Spirulina as a low-calorie, high-protein, mineral and vitamin food supplement are now well established and recognized worldwide. Studies have shown that spirulina can lower cholesterol levels, stimulate the immune system and be effective in the treatment of obesity, heartdisease, premenstrual stress, arthritis, anaemia and osteoporosis.

Spirulina is also a rich source of betacarotene, a natural antioxidant, which the body converts to vitamin A and which plays a protective role in the human organism. Recent studies have concluded that a diet rich in vitamin A and provitamin A can lower the risk of cancer. Betacarotene is considered a more effective antioxidant than synthetic trans betacarotene. Positive results have also been seen in performance and stamina levels when Spirulina is taken as a sports supplement; the blue-green alga has a high level of biotin, which is an inhibitor of lactic acid in muscles.

Scientific reference from: A typical analysis of Spirulina product. Based on sample of dried Spirulina powder of Turkish Algae Company analyzed by Republic of Turkey Ministry of Agriculture and Rural Affairs Izmir Province Control Laboratory and Ege University (Koru et al., 2008)

In 1970’s, Spirulina underwent extensive safety studies with animals and fish. Independent feeding tests in France, Mexico and Japan showed no undesirable results and no toxic side effects on humans, rats, pigs, chickens, fish and oysters. Many independent rat feeding trials were conducted in Japan and no negative effects at all were found for acute or chronic toxicity or reproduction

Spirulina as a medicine. Scientific evidence.

1) Nutritional and Therapeutic Potential of Spirulina. Khan et al. Current Pharmaceutical Biotechnology, 2005, 6 373-379.

The Spirulina species contain significant amount of valuable proteins, indispensable amino acids, vitamins, beta-carotene, mineral substances, essential fatty acids, polysaccharides, glycolipids and sulpholipids.

Several scientific findings suggested that Spirulina proved to be a potential and ideal candidate for conjugative therapy due to the possible synergetic effect of many phytochemicals in whole cell. It has demonstrated that the use of Spirulina and its extracts may reduce cancer and viral diseases.

2) Effects of a Spirulina-Based Supplement on Cytokine Production from Allergic Rhinitis Patients. Mao et al. Journal of Medicinal Food 8 (1) 2005, 27-30

Allergic patients consuming 2,000 mg of Spirulina daily can reduce the production of IL-4 from PHA-stimulated PBMCs by 32%.

3) Protective effect of aqueous extract from Spirulina platensis against cell death induced by free radicals. Chu et al. BMC Complementary and Alternative Medicine 2010, 10:53

The potential of incorporating Spirulina extract as a functional ingredient in food products and beverages to enhance their antioxidant capacity is worth exploring.

5) A Review On Culture, Production And Use Of Spirulina As Food For Humans And Feeds For Domestic Animals And Fish. Food and Agriculture Organization of the United Nations, Rome, 2008

Spirulina appears to have considerable potential for development, especially as a small-scale crop for nutritional enhancement, livelihood development and environmental mitigation. In particular, the production and use of spirulina has the following advantages:

  • it provides an easily digestible high (c. 60 percent) protein product with high levels of β-carotene, vitamin B12, iron and trace minerals and the rare essential fatty acid γ-linolenic acid (GLA). In addition, it has no obvious negative cultural or religious issues associated with its consumption;
  • its production occupies only a small environmental footprint, with considerable efficiencies in terms of water use, land occupation and energy consumption when compared to traditional terrestrial crops;
  • its production is especially suitable to saline and alkaline conditions that are often unfavourable to traditional crops and are frequently occupied by disadvantaged people suffering from, or vulnerable to, natural disasters;
  • its production can be conducted at a number of different scales, from household “pot culture” to intensive commercial development over large areas;
  • it has the potential for integration with rural organic waste treatment processes to improve both environmental conditions and improve energy transfer efficiencies;

6) Spirulina paltensis: Food and Function. Hoseeini et al. Current Nutrition & Food Science, 2013, Vol 9, No. 2

Research results show that using Spirulina platensis powder in food products is very practical and functional. Increased demand for healthy food, more global acceptance of fortified foods by Spirulina platensis, low production cost and its high nutritional content enhance its application in food industry.

Spirulina and Bodybuilding. Scientific evidence.

Despite being around for ages, the effect of spirulina on enhancing exercise performance is a relatively new area of study. Nevertheless, there are some studies that support Spirulina as an ergogenic aid. One study found that supplementing with 2 g spirulina per day for 8 weeks was able to increase quadriceps peak and average isometric force of subjects compared to those receiving a placebo (Sandhu et al, 2010). A similarly positive effect on muscle endurance can also be found with spirulina supplementation, in which 6 g/day of spirulina per day for 4 weeks increased endurance exercise performance, fat oxidation, and reduced oxidative damage by free radicals (Kalafati et al, 2009). The effect of spirulina on providing antioxidative protection against muscle damage has been supported by other studies (Lu et al, 2006). This protective mechanism may be the reason for spirulina being able to extend endurance, and possibly speed up recovery.

Spirulina Powder Side effects and Syptoms

A few side effects and contraindications have been reported with Spirulina use. This is natural for almost all foods under specific environmental circumstances or for peoples with specific health conditions like allergies etc. The most frequently reported adverse effects are headache, muscle pain, flushing of the face, sweating, and difficulty concentrating. In case of repeatedly showing those symptoms stop talking Spirulina and consult with your doctor.

Spirulina should be avoided by people who have the metabolic disorder phenylketonuria as all the protein rich foods that affects this dicease..

Spirulina is not recommended for people who have allergies to seaweed or seafood.

Not a lot is known about its effects during pregnancy and breast feeding. With that in mind, make an informed decision to consume it if you are pregnant or breast feeding or ask you physician’s advice.

Blue-green algae harvested in uncontrolled culture conditions may be contaminated with heavy metals that can lead to liver damage, diarrhea and vomiting. One approach to circumvent this is to grow spirulina in an 'organic' way. USFDA's National Organic Standard Boards have guidelines to produce spirulina as 'organic' and also certifies the same. Such organic certifications will alleviate the concerns about spirulina being a safe vegetarian nutritional and dietary supplement.

To minimize any possible side effects, it is important to source the supplement from reputed organic stores. This will help ensure that the spirulina you are consuming is free of dangerous contaminants such as microcystins, harmful bacteria and toxic metals. This is not exactly a problem of the spirulina but of the water in which it grew. If the water was contaminated then so too could be the spirulina, hence always ask for organic, responsibly sourced product.

How to be secure against negative effects of Spirulina in two simple steps

  • To make sure your spirulina is safe, research well about your brand, and find out where and how if it produced. If you are not provided with clear information – avoid it, and it is as simple as that. Here we try to give you all the information you need to evaluate your supplier.

  • When you first start eating Spirulina in any form, start small and see if there is any side effects before you increase your dosage. The body need some time to adapt, and does not know how to react to the cyanobacteria (the blue-green algae) at first.
