The alga, also known as ‘food of the gods’, is one of the oldest inhabitants of our planet. It is a seaweed called Spirulina for its typical spiral shape, colored between green and blue. Spirulina is considered to be one of the most complete foods for the human organism, so much so that it has also been called ‘twenty-first century supremacy’. It was declared “food of the future” by the FAO in 2008.

1. What is spirulina

Arthrospira Platensis, better known as spirulina, is a bacterium belonging to the cyanobacteria class, more commonly it is defined as a microalgae with a blue-green color and perfect spiral shape. This is why you will also find it under the name "spirulina algae".

From a biological point of view, spirulina is one of the oldest inhabitants of the planet, an evolutionary bridge between bacteria and algae. In nature it is widespread in tropical and subtropical regions, living in warm, brackish water lakes with an alkaline pH. The high nutritional value in terms of concentration of proteins, vitamins, antioxidants, omega 6, omega 3, mineral salts, essential amino acids and other nutrients, the presence of iron and natural pigments such as phycocyanin, beta-carotene and chlorophyll, together with its easy digestibility and assimilation, have made spirulina a fundamental resource for many civilizations, from ancient times to the present day.

2. Spirulina Properties

Spirulina Becagli is grown, harvested and processed in the Grosseto plant, in Tuscany. It is here that it is dried at low temperatures to preserve all its properties. It is a 100% natural product, guaranteed GMO-free, without additives and pesticides, certified BIO and Vegan OK. But what exactly does spirulina contain?

Spirulina algae contains a series of nutritional components that make it a real Superfood and is composed on average of 5% water, 24% carbohydrates, 8 % fat and 60% vegetable proteins, easily assimilable by our body.

Dried spirulina has a high protein value: between 55-77 % of its weight. It also contains phycobiliproteins, in particular Phycocyanin and Allophycocyanin which are also rich in antioxidant properties.

Amino acids are elements that make up the proteins consumed by our body. When we ingest food, our digestive system is able to break down proteins into simple amino acids so that our body can assimilate them. However, among the amino acids, there are some (eight to be exact) that our body is not able to synthesize independently: the essential amino acids. Spirulina is one of the few foods present in nature that contains them all in the same proportions as breast milk, ready to be assimilated.

Acids Unsaturated fats are "healthy" fats, i.e. those capable of lowering the number of triglycerides in the blood and reducing cholesterol.

Among these, in particular, are present in spirulina:
- linoleic acid;
- alpha-linoleic acid;
- gamma-linoleic acid;
- stearidonic acid;
- docodahexaenoic acid;< br/>- arachidonic acid;
- eicosapentaenoic acid

Spirulina is also rich in vitamins useful to the human body for a correct balance of its functions. In particular, the seaweed contains the following:
- vitamin A;
- vitamin D;
- vitamin C;
- vitamins E;
- group vitamins B ( B1, B2, B3, B6, B9)

This blue-green algae also contains many mineral salts and microelements essential for our body: calcium, iron, zinc, potassium, selenium, sodium, copper, phosphorus, magnesium, manganese. We can therefore define it asa food with complete protein content.

Benefical properties

It has many beneficial and therapeutic properties that are useful for our body:

Antioxidants: vitamin E and beta carotene give the seaweed anti-aging effects useful for fighting against the distributive action of free radicals

Anti-inflammatory: the fatty acids present in spirulina exert anti-inflammatory, antiviral and antimicrobial actions, producing substances called prostaglandins

Detoxifying: the algae supports the body in the elimination of heavy metals thanks to the plant pigments that compose it such as chlorophyll and phycocyanin

Vasodilators : xanthophylls (substances belonging to the carotenoid family) regulate blood pressure by acting on the substances responsible for the vasoconstriction of blood groups

Anticoagulants: omega3 fatty acids have anticoagulant properties and promote fluidity of the blood, hindering the formation of clots.

Immunomodulatory: rich in vitamins A, B, D, fundamental for health, spirulina algae guarantees support for our defenses Furthermore, the concentration of mineral salts, calcium and magnesium is fundamental for the bones and the nervous system.

The consumption of spirulina algae is recommended for anyone who wants a good nutritional balance and stay healthy . The foods we eat today are poor from a nutritional point of view and it is very important to supplement our diet with natural, non-synthetic products: spirulina makes up for the lack of vitamins, mineral salts, proteins and other nutrients.

3. Spirulina benefits: what is it for

If after reading all its properties, you are still wondering what spirulina is actually used for, you should know that this algae has countless beneficial effects for health. The main benefits, which everyone knows by now and it is almost superfluous to remember, are three: spirulina gives useful energy to better face long days of work and study, it helps and supports the immune system and it is perfect for integrating a slimming diet, as it activates the metabolism, gives a sense of satiety and allows you to eat less.

Let's see what the other benefits of spirulina algae:


Among the benefits of spirulina there are certainly those on the skin. For example, spirulina regulates sebaceous secretion, allows you to promote the production of collagen by the tissues and therefore have plumper and firm skin, furthermore, being rich in beta-carotene, it promotes a healthy and long-lasting tan. Learn more about the topic in our blog, read the article spirulina for the skin.


There are also numerous benefits on the hair, try using it in powder form, with a compress or by mixing it with a natural shampoo. The use of this algae helps to restore brittle and dull hair . Spirulina algae is an effective natural product for the well-being of hair, it makes it robust, strong, soft, shiny and deeply nourished. It also helps to reconstruct the entire structure of the hair thanks to the essential amino acids, which promote the synthesis of keratin, the supporting structure of the hair. Learn more about the topic in our article spirulina for hair.


Moreover, among the beneficial effects of spirulina we find those for diabetes. FOR ANEMIA

Thanks to the presence of iron and provitamin B12, spirulina is able to help those suffering from anemia. The iron present in spirulina is also very suitable for those who follow vegetarian and vegan diets and need to integrate it into their diet in a natural way.


Spirulina also has beneficial effects against anxiety, improving memory and concentration. We talked about how spirulina helps you concentrate in more depth in our article, you can read it here.


< p>The high quantity of antioxidants in spirulina allows you to prevent free radicals and carry out an anti-aging action and prevention against premature aging of the organism, strengthening the immune system .


It has energizing, anti-inflammatory, antioxidant and detoxifying properties, that's why it is highly recommended for those who practice sports.


Spirulina can also help in choosing to adopt a healthy diet. Both in cases of malnutrition and overweight spirulina proves to be a very valid natural supplement to support a healthy and nutrient-rich diet. In cases of malnutrition it helps prevent the onset of anemia and helps to provide a source of vitamins, fats, proteins and amino acids easily assimilated by the body. Taken before meals in cases of overweight, however, it accelerates the onset of a sense of satiety thanks to the abundance of nutrients and their effect on the secretion of cholecystokinin and can in this sense find space in dietary-behavioral therapies aimed at reducing body weight.Learn more about the topic in our article: spirulina for weight loss.


The intake of Spirulina algae reduces triglycerides in the blood, stimulating the increase in the so-called 'good cholesterol' (HDL) and instead reducing the bad one.


Spirulina algae, if taken daily and in correct doses, even helps prevent cardiovascular diseases, thanks to the important presence of omega-3 and omega-6, and to control blood sugar levels in type 2 diabetics, helping to reduce blood sugar spikes.

4. spirulina contraindications

The use of spirulina algae, if of quality and produced in a controlled environment and in compliance with regulations, has no particular contraindications. However, there are some cases in which its use may not be recommended.

Contraindications are highlighted for people who use anticoagulant drugs because the vitamin K contained in it could counteract the effect of the drug


Even people suffering from phenylketonuria, who are unable due to a congenital defect to break down the amino acid phenylalanine, should pay attention to the use of spirulina since the phenylalanine itself contained in inside the alga could accumulate in the body in toxic quantities, also creating serious damage.

Furthermore, given that spirulina stimulates the immune system, people suffering from autoimmune diseases should pay attention to its use.

Among the most common contraindications relating to the use of spirulina, we then find people with thyroid-related problems, even if in reality this is a false myth, as spirulina is grown in fresh water, without iodine.

It is always advisable to consult your doctor in the most thorny cases.< /strong>

5. Types of spirulina

Becagli Spirulina is a natural, organic food and preserves the integrity of the original nutritional principles in all the formats in which it is processed. Our spirulina is available online in all its forms:

*Organic spirulina supplements are registered to the Ministry of Health, they are naturally gluten-free and VeganOkcertified.

6. How to take Spirulina

Spirulina can be taken in various ways, depending on the format in which you choose to use it, in general it is recommended to take from 2 to 5 grams of dried spirulina per day.

If you choose to use spirulina powder or spirulina in sticks, the suggestion is to mix 3 grams of product with a yogurt, a fruit juice or a centrifuge in order to mix the powder as best as possible. A tasty idea? Try mixing a glass of vegetable coconut milk with a banana and a 3g sachet of Spiruday!

If you choose spirulina supplements, the recommended daily dose is 6 capsules or tablets of 500 mg per day to be swallowed with water. 6 capsules/tablets, in fact, correspond to 3 grams of dried spirulina.

It can be taken at any time of the day: at breakfast or lunch for those following a normal diet; in the morning and/or before or after training for those who practice intense sporting activity.

The quantity of dried spirulina to be taken can be higher or lower, depending on needs and depends on several factors such as eating habits, lifestyle, metabolism and set objectives, which vary depending on the subject. For those who practice intense physical activity, the daily dose can be higher, up to 10-15 grams, but be careful to increase your water intake during the day.

Important: food supplements, such as spirulina, are not intended as meal replacements, but serve to integrate a varied and balanced diet, within a healthy lifestyle.

Becagli spirulina is continuously monitored and controlled, in order to guarantee a safe, certified organic product, without additives, pesticides, preservatives and dyes.

It is important to choose a product of agriculture and Italian and certified organic supply chain. Spirulina, if not carefully cultivated and dried, risks losing its beneficial properties, even in some cases becoming harmful to the body. This happens because spirulina, growing in water, absorbs everything it comes into contact with, so if the water is not filtered and purified it may contain heavy metals which will then be assimilated by the body when you take low quality spirulina.

7. Spirulina side effects

Spirulina, as reported by various sources, including the FDA (the American government body that deals with the regulation of foods, drugs and supplements), is generally considered safe. However, it is important to ensure that it is not contaminated with microcystins or anatoxins, toxic substances that can trigger adverse effects such as stomach pain, nausea, vomiting, liver damage, weakness, thirst, rapid heartbeat, shock.

It is also good to remember that spirulina can absorb heavy metals. For this reason it is essential to purchase only safe products, grown in protected environments, without contact and contamination with the external environment as occurs in Becagli Spirulina plants.

Being in fact a food, intake of spirulina does not appear to have negative interactions with the use of drugs.

8. Why choose Spirulina Becagli

Spirulina Becagli grows in a natural environment, but controlled and protected. It is grown in open tanks inside automated greenhouses which allow control of temperature, sun exposure and ventilation. All this without the risk of external contamination. The harvest takes place via an automated system, without contact with the personnel in charge and finally the drying takes place which takes place at a low temperature (at 40° for approximately 6-8 hours) in order to keep the nutritional characteristics unchanged.

The large spirulina producers often use the spray-dry drying method which consists of burning the spirulina at over 100°, a method that is certainly faster, but which does not preserve the organoleptic qualities, protein and vitamin characteristics of spirulina.

Becagli spirulina is continuously monitored and controlled, in order to guarantee a safe product, good to eat, certified organic, without additives, pesticides, preservatives and colourants.

It is important to choose a product from Italian agriculture and supply chain and certified organicsince spirulina, if not cultivated and dried carefully, risks losing its beneficial properties , even becoming harmful to the organism in some cases.

This happens because, growing in water, the algae absorbs everything it comes into contact with, so if the water is not filtered and purified it may contain heavy metals which will then be assimilated by the body when low quality spirulina is taken.
