Spirulina (Spirulina platensis) is a blue-green microalgae that grows naturally in alkaline lakes of tropical and subtropical regions. Andes spirulina stands out for its exceptional growing conditions: cultivated at altitude, above 2,500 metres in Ecuador, it benefits from intense sunlight, pure volcanic spring water and air free from industrial pollution. These unique geographic conditions allow the spirulina to develop a particularly high content of phycocyanin, the blue pigment that gives it its characteristic colour and antioxidant properties. Unlike some spirulina grown in artificial ponds at low altitude, Andes spirulina retains a dense, authentic nutritional profile. It is Ecocert-certified, guaranteeing an environmentally responsible production method free of pesticides or synthetic chemical fertilisers.

Spirulina has been recognised for decades as a leading food supplement. Its richness in complete protein makes it a valuable ally for athletes, vegetarians, vegans and anyone wishing to naturally increase their protein intake. Its iron content contributes to reducing tiredness and to normal energy metabolism, of particular interest for menstruating women or anyone with higher iron needs. Phycocyanin, the unique blue pigment of spirulina, is a powerful antioxidant that helps protect cells from oxidative stress. B vitamins, particularly B12, play a key role in normal nervous system function and in reducing tiredness. Beta-carotene, a precursor of vitamin A, contributes to the maintenance of normal skin and normal vision, while selenium contributes to normal immune system function.

The 500-tablet format is the most cost-effective for regular spirulina users. At 6 tablets a day (the recommended daily dose), this bottle provides around 83 days of use — nearly three months of continuous supplementation, at a noticeably lower price per gram than smaller 100 or 200-tablet formats. Tablets are easy to carry, require no preparation and offer precise dosing, avoiding the strong taste and intense green colour that can put some people off spirulina powder. It’s best to start gradually — 2 tablets a day the first week, then increasing progressively to 4-6 tablets a day — taken with morning or midday meals for optimal nutrient absorption.

At 6 tablets a day, a 500-tablet bottle lasts around 83 days. Spirulina combines well with vitamin C, which supports the absorption of its iron content, and can also be taken alongside magnesium, omega-3 or probiotics.

Not recommended for people with phenylketonuria, due to its phenylalanine content. Food supplement. Not a substitute for a varied, balanced diet and a healthy lifestyle. Do not exceed the recommended daily dose. Keep out of reach of children. If in doubt or if you are on medical treatment, seek advice from a healthcare professional.

How do I choose a good-quality spirulina?

Not all spirulina is equal. Geographic origin matters: spirulina grown at altitude, in pure water and strong sunlight, develops a superior nutritional profile. Organic certification (Ecocert for Andes spirulina) guarantees the absence of pesticides and chemical fertilisers. Phycocyanin titration is a key quality indicator — the higher it is, the richer the spirulina in antioxidants. Low-temperature drying also matters, as it preserves fragile nutrients like vitamins and enzymes. Finally, the ingredient list should be as short as possible: ideally, just pure spirulina and an anti-caking agent.

Is Andes spirulina suitable for vegans?

Yes, Blue-Green Andes Spirulina is perfectly suited to vegan diets. It contains no animal-derived ingredient, and provides complete protein with all essential amino acids, vitamin B12 and iron — three nutrients often critical in a vegan diet. The tablet itself contains no gelatine.
