Spirulina (Arthrospira platensis) is a cyanobacteria that has existed for over three billion years, one of the most nutrient-dense foods known. It contains 60–70% complete protein — all eight essential amino acids — plus bioavailable iron, beta-carotene, B vitamins, vitamin E, minerals (zinc, manganese, copper) and GLA.

Phycocyanin is spirulina’s characteristic blue pigment, a phycobiliprotein playing a fundamental role in photosynthesis and one of the most studied natural antioxidants. Dynveo’s spirulina reaches a minimum 25% phycocyanin, up to 35% depending on batch, thanks to drying below 40°C — versus 5–15% for many industrial, high-heat dried spirulinas.

Grown in southern France with favourable climate and recognised expertise, under strict EU food-safety standards, with organic certification guaranteeing no synthetic pesticides, herbicides or fertilisers, and full traceability from pond to packaging.

Drying is the most critical step in spirulina production. Dynveo dries below 40°C, preserving heat-sensitive phycocyanin, vitamins and enzymes — slower and costlier than conventional drying, but yielding a visibly deeper green colour, evidence of preserved pigments and actives, verified by independent lab analysis on each batch.

Take 4 to 6 tablets a day with a large glass of water, with meals. Beginners should start with 2 tablets a day in the first week, then increase gradually. Can be taken year-round, with more intensive courses in winter, at seasonal changes, or during intense training or fatigue.

Does not replace a varied, balanced diet or healthy lifestyle.

Tablets vs. strands — what’s the difference?

Tablets are compressed spirulina powder with no chemical binders at Dynveo; strands keep the natural dried shape uncompressed. Both offer the same nutritional quality — tablets are easier to dose and carry, strands blend easily into smoothies and juices.

Can children take spirulina?

From age 5, with adjusted dosing (generally half the adult dose) — consult a paediatrician or healthcare professional before supplementing a child.

How long does a 200-tablet pot last?

At 6 tablets a day (optimal dose), about 33 days; at 4 tablets a day, about 50 days — ideal for a first try before moving to the larger 500-tablet format.
