What exactly is Spirulina?
The blue-green powder made from photosynthetic cyanobacteria.
Spirulina is the familiar commercial name used for dried biomass produced from photosynthetic cyanobacteria belonging to the group historically associated with Arthrospira. It is widely described to customers as blue-green algae powder.
Customers may search for Spirulina Powder, blue-green algae powder, algae powder or Arthrospira powder in the UK. These terms describe the same broad ingredient category supplied here in a focused loose-powder format.
The Crown Supplements formula keeps Pure Spirulina Powder clearly identified instead of burying the ingredient inside an undefined green blend or extending the pouch with production-focused additions.
The familiar ingredient name
Spirulina is the direct customer-facing name used for the deep green powder supplied inside the pouch.
The name is widely used across powder, capsule and food-supplement products containing dried Spirulina biomass.
The recognised category name
Blue-green algae is the familiar descriptive term commonly used for Spirulina, although the ingredient belongs scientifically to a group of photosynthetic cyanobacteria.
Both terms help customers identify the same distinctive powder category without turning the product into a vague multi-green blend.
The Spirulina can disappear
Broad green-powder blends can leave customers guessing how much Spirulina actually forms the finished product.
One named ingredient kept in focus
The formula is centred directly on Pure Spirulina Powder rather than an undefined collection of green ingredients.

Why choose this Spirulina Powder?
The Spirulina should lead the formula.
British shoppers choosing Pure Spirulina Powder are paying for the named blue-green algae ingredient. Crown Supplements keeps the pouch centred on that powder instead of turning the formula into a production checklist.

Recognisable identity
Spirulina and blue-green algae identify the powder category directly.
Loose powder format
The ingredient is supplied directly as powder in a practical resealable pouch.

The Crown Supplements formula standard
Built around Spirulina—not manufacturing convenience.
When a powder includes filler padding, bulking materials, binders, anti-caking agents or machine flow agents, part of the pouch is being built around production instead of the Spirulina customers came to buy.
They may help the machine. They are not the reason the customer buys the powder.
Choose the powder quantity
Four quantities. One focused Spirulina formula.
Customers across Great Britain can select 100g, 250g, 500g or 1kg of Pure Spirulina Powder. Every pouch contains the same focused single-ingredient formula.
