Organic Spirulina Powder - 500 g images
Organic spirulina powder 500 g - 12.3% phycocyanin
Organic spirulina powder needs no introduction: this micro-alga has been at the forefront of vegetarian and vegan eating for many years, particularly for its plant protein content (66.3 g per 100 g).
🟢 What is organic spirulina powder?
Spirulina is actually a micro-alga, more precisely a microbial organism (cyanobacterium) with no distinct nucleus. If you look more closely, it has a spiral shape, which is where its name comes from. It appeared on Earth 3.5 billion years ago - and it has developed extraordinary resistance to survive the profound climate changes that separate us from that time.
It contains 66.3 g of protein per 100 g, with an amino acid profile found in very few plants - we have detailed it in our feature on the complete plant proteins of seaweed. It also provides iron: 81.4 mg per 100 g, i.e. 2.4 mg per 3 g daily dose (17% of the nutrient reference values). Iron contributes to normal formation of red blood cells and haemoglobin.
🟢 Why our spirulina powder is spray-dried
Convection drying methods on trays, commonly practised in small artisanal operations in France and elsewhere, have drawbacks related to the length of the drying process. The work of Hélène Desmorieux, doctoral student and researcher at LAGEP, a laboratory jointly run by Université Claude Bernard 1 in Lyon and the CNRS, shows that the best drying method for optimal preservation of spirulina's nutrients is spray drying, recognised by Ecocert.
> This nebulisation method allows rapid dehydration of the algae and preservation of their nutritional qualities. The spirulina is sprayed into a hot chamber where it comes into contact with hot air. The temperature is generally kept below 50 °C to avoid degrading heat-sensitive nutrients and enzymes.
🟢 How to take spirulina powder: dose and timing
Spirulina powder can be taken at any time of day. We advise against taking it in the evening, as it may have a slightly stimulating effect in some sensitive people.
Recommended daily dose: 3 g - the equivalent of one teaspoon diluted in a fruit or vegetable juice, a smoothie, plant milk, a yoghurt...
The gradual dose increase we recommend:
- Days 1 to 7: 1 g per day.
- Days 8 to 14: 2 g per day.
- From day 15: 3 g per day, the maintenance dose.
Why so gradually? Because the body needs a few days to get used to such a dense food. Everyone at their own pace.
Combine it with a dash of lemon juice. Using spirulina in cooking is in fact the best way to enjoy it all year round - there is no shortage of recipe ideas, and its intense green colour gives an immediate wow effect!
> Our organic spirulina is fat-soluble, meaning that it dissolves easily in a fatty preparation or liquid, and forms lumps in a liquid made up mostly of water. Many people eat it alternately with organic chlorella powder.
🟢 How to eat spirulina powder every day
Spirulina forms lumps in water. This is not a flaw. It is proof that it is fat-soluble - and the key to all the recipes that follow: give it a fat, and it dissolves on its own.
- The morning smoothie : 3 g in a banana-mango smoothie, with a dash of lemon juice. It is the simplest way to start.
- The green vinaigrette : 1 g whisked into olive oil before adding the vinegar. The spirulina dissolves in the fat, never any lumps. Frankly, it is my favourite - and nobody guesses what is in it.
- The plant-based yoghurt : 3 g in a soya or coconut yoghurt, with a spoonful of almond butter. The fat from the nuts does all the work.
And for the very first days, follow the protocol above: 1 g, then 2 g, then 3 g. That's it. Nothing more complicated.

🟢 Frequently asked questions about spirulina powder
How much spirulina powder per day?
The recommended daily dose is 3 g (about 1 teaspoon), not to be exceeded. Start with 1 g/day and increase gradually to let the body get used to it.
Can you take spirulina every day?
Yes, spirulina can be eaten daily as part of a varied and balanced diet, at 3 g per day. For prolonged use, it is advisable to choose a certified spirulina and to seek the advice of a healthcare professional.
Is spirulina dangerous?
Spirulina is generally very well tolerated. The main points to watch concern the quality of the product (uncertified spirulina may contain microcystins or other contaminants) and certain particular situations: autoimmune conditions, phenylketonuria, anticoagulant treatment. If in doubt, ask your doctor and refer to the assessment by the ANSES.
When should you take spirulina powder?
In the morning or during the day, preferably before a meal. Avoid taking it in the evening - spirulina may have a slightly stimulating effect in some sensitive people, which can disturb sleep.
How to mask the taste of spirulina powder?
Its pronounced sea taste is very easily hidden in a banana-mango smoothie, an orange juice or a soya yoghurt. Its intense green colour, on the other hand, is hard to hide! Find our 12 tips for masking the taste of spirulina on our blog.
Who should not take spirulina?
Four situations call for prior medical advice, or even abstaining:
- Phenylketonuria : absolute contraindication (spirulina contains phenylalanine).
- Autoimmune conditions : multiple sclerosis, lupus, rheumatoid arthritis.
- Anticoagulant treatment : because of the vitamin K content.
- Haemochromatosis or iron overload: spirulina contains iron (2.4 mg per 3 g dose).
For full information, refer to the assessment by the ANSES.
Can spirulina make you dizzy?
The side effects reported at the start of a course - mild headaches, digestive upsets, a feeling of light-headedness - are generally linked to an initial dose that is too high. This is exactly the reason for the gradual increase protocol: 1 g, then 2 g, then 3 g per day. If a symptom persists, stop taking it and consult a healthcare professional.
