Phycocyanine is the blue pigment-protein of spirulina (Arthrospira platensis), known for its antioxidant and immune-supportive properties. The exclusive Phyco-Lyo process uses cold freeze-drying that preserves the molecular integrity of phycocyanine and ensures exceptional bioavailability. Each Phyco-500 capsule delivers 500 mg of pure, 100% natural phycocyanine, with a pharmaceutical-grade purity index of 2.82.

Phycocyanine is one of the most powerful natural immune-system stimulants, helping strengthen the body’s defences against external stressors — particularly valued during seasonal changes or fatigue. Its strong antioxidant action neutralises free radicals and helps protect cells from oxidative stress. Phyco-500 is also recognised for supporting overall vitality and energy, making it a valuable ally for active people, athletes or those in convalescence.

Phycocyanine naturally stimulates red blood cell production, improving oxygen transport in the body — a property of particular interest to athletes seeking better endurance and faster post-exercise recovery. It is also known for its role in lactate recycling, reducing the feeling of muscle fatigue after training.

The recommended dose is 1 to 2 Phyco-500 capsules per day, ideally taken before breakfast or lunch. A minimum three-month course is recommended to let phycocyanine act durably across several cell cycles. Tip: open the capsule into a glass of water before taking it to enjoy phycocyanine’s striking blue colour and optimise assimilation. Beginners should start with one capsule a day for the first week, then increase gradually.

Phyco-500 is manufactured to a rigorous methodology in partnership with a specialist laboratory, with full analysis transparency. The product is DGAL-labelled under no. 2024-1-1264. The capsule shell is made from plant-based pullulan, making Phyco-500 100% vegan. The 30-capsule bottle is packed in fully recyclable packaging by workers with disabilities at a French ESAT (sheltered workshop).

How long should a phycocyanine course last?

To feel the full benefits of phycocyanine, a minimum three-month course is recommended. The 30-capsule Phyco-500 bottle covers one month at one capsule a day, so a full three-month course needs three bottles. First effects on vitality and immunity are usually felt after 2-3 weeks of regular use.

What’s the difference between phycocyanine and spirulina?

Spirulina is the whole algae, rich in protein, vitamins and minerals. Phycocyanine is spirulina’s active blue pigment, extracted and concentrated. One Phyco-500 capsule contains 500 mg of pure phycocyanine, equivalent to the active content of several grams of spirulina, giving a more targeted action on immunity and antioxidant support.

Why might phycocyanine cause a slight detox effect at first?

Phycocyanine stimulates cellular functions and can trigger a mild detoxification reaction in the first few days — a sign the product is working. To limit this, start with one capsule a day in the first week and increase the dose gradually.
