What is spirulina ?

Spirulina is an alga, which due to its success is now produced in a controlled way around the world, wherever the climate allows it. Low in calories, it contains a great richness of nutrients. This seaweed has many nutritional benefits, and can, in particular, help cover the need for vitamin B12. 

It also offers less well known environmental benefits. Spirulina is actually able to produce oxygen and capture CO2. As far as its production is concerned, it is quite simple and environmentally friendly.

In other words, this microorganism does not contribute to the soil erosion and pollution for which modern agriculture is responsible. No pesticides, herbicides or fungicides are used in the production of spirulina, which is grown above ground. It then uses 30 times less water than, for example, soya cultivation. And the water used for its cultivation can also be reused after filtration.

It is mainly for these reasons that I decided to tell you about this superfood, which is one of the few products to fill all our daily nutritional needs.

Benefits and properties of spirulina

This type of cyanobacteria (also called blue-green algae) can improve blood lipid levels, suppress oxidation, lower blood pressure and lower blood sugar levels. Although further research is needed before solid claims can be made, this microorganism may be one of the few superfoods that really deserves this title.

Spirulina is a nutrient concentrate. It is extremely rich in beta-carotene, iron, vitamin B12, vitamin E, proteins, minerals and trace elements (calcium, phosphorus, magnesium, zinc, copper). It also contains chlorophyll and phyocyanine, a pigment with antioxidant properties.

In a number of countries, to combat malnutrition, its richness in nutrients and its local culture are presented as assets. Several studies have also shown that this seaweed helps reduce total cholesterol and LDL (bad cholesterol) levels. Similarly, an increase in good cholesterol, HDL, was also observed.

However, it is advisable to prefer dry and cold pressed spirulina in order to preserve all its nutritional qualities.

How to consume ?

The two most commonly used forms are powder and tablets. Spirulina is also used in the composition of certain protein mixtures and energy powders. You can mix a teaspoonful of powder in a glass of water or juice and drink it directly, or you can add it to a shake. Caution: A small amount will change the color of your drink to a deep greenish blue, almost black.

The recommended daily dose is 1 to 3 grams, but doses of up to 10 grams per day have already been used effectively. However, start with 1 tablet a day and gradually increase the amount. Too high initial doses can cause headaches and digestive problems due to its detoxifying properties.

Nutraceuticals: what is it ?

A nutraceutical is any food that has a beneficial effect on the body. Most functional foods naturally contain bioactive components. Grapes, for example, contain polyphenols, natural antioxidants that play a role in cancer prevention. 

When we talk about functional foods, we sometimes use the term nutraceutical. In this case, the word refers to the active ingredient in the food, which is extracted and made available as capsules or tablets.

What is the danger of spirulina ?

There are no contraindications for spirulina and the consumption of reasonable doses is without risk to health.

Spirulina, however, may contain several contaminants. On the one hand, cyanobacteria of other genera and their toxins have been found in some batches. On the other hand, the presence of metallic traces has been mentioned in wild or cultivated spirulina.

In this context, consumers are recommended to favour the best controlled supply channels (compliance with regulations, traceability, manufacturer identification).
